Procédé pour produire des préparations intéressantes.
On a trouvé qu'on peut produire des préparations intéressantes avantageusement utilisables en particulièr dans l'industrie textile en mélangeant des esters issus d'acides dicarboxyliques renfermant des groupes sulfoniques et d'alcools aliphatiques à poids moléculaire 'élever ou des esters sulfuriques issus d'alcools aliphatiques secondaires à poids moléculaire élever ou les sels, solubles dans l'eau de ces esters, avec d'autres substances ayant un pouvoir dispersif, solvant ou détersif et le cas échéant avec d'autres substances.
<Desc/Clms Page number 2>
Des esters carboxyliques convenables pour la production de ces préparations sont par exemple ceux des acides sulfomalonique , sulfo-succinique, sulfo-adipique ou sulfo-phtalique avec les alcools hexylique, octylique, dodécylique ou undécylique, ainsi qu'avec l'alcool iso-octylique, le -éthyl-hexanol, ou des alcools secondaires comme l'hexylheptyl-carbinol, le dioctyl-carbinol, le dodécyl-undécyl- carbinol, etc. Les esters en question peuvent s'obtenir par exemple par sulfonation des esters carboxyliques exempts de groupes sulfoniques ou par estérification des acides carboxyliques renfermant des groupes sulfoniques au moyen des dits alcools, par exemple par le procédé décrit au Brevet belge du 6 mai 1931 N 379.608.
On envisagera également les esters sulfuriques d'alcools aliphatiques secondaires à poids moléculaire élevé, comme l'heptyl-octyl-carbinol, le dodécyl-undécyl-carbinol, puis ceux d'alcools qui se forment par cétonisation d'acides carboxyliques aliphatiques, par exemple même de ceux qu'on peut obtenir en oxydant des paraffines, et par hydrogénation subséquente. Les dits composés renfermant des groupes sulfoniques peuvent s'employer d'une façon particulièrement avantageuse sous forme de Leurs sels, par exemple de sodium, de potassium, d'ammonium, d'amines ou d'oxalcoylamines.
Comme substances convenables ayant un pouvoir dispersif, solvant ou détersif destinées à être mélangées avec les dits esters sulfo-carboxyliques ou sulfuriques on envisagera par exemple les acides sulfoniques d'hydrocarbures aromatiques alcoylés, par exemple les acides naphtalènesulfoniques propylés ou butylés, puis les acides sulfoniques aliphatiques à poids moléculaire élevé, par exemple l'acide oxy-octodécane-sulfonique, l'acide sulfo-palmitique, ainsi
<Desc/Clms Page number 3>
que les produits de condensation d'acides à poids moléculaire élevé provenant d'huiles ou de graisses avec des acides aminoalcoyl-sulfoniques ou-carboxyliques, enfin les huiles pour rouge turc ou les savons ordinaires.
Comme second constituant dans le cas présent on peut aussi employer des esters sulfuriques d'alcools gras, par exemple ceux des alcools laurique ou oléique.
Des substances ayant une action dispersive, solvante ou détersive qui conviennent souvent aussi sont des produits de l'action de fortes quantités d'oxyde d'sthylène, par exemple de 3, 4,10 molécules-gramme ou plus d'oxyde d'éthylène sur des composés présentant un atome d'hydrogène susceptible de réagir, par exemple dans un groupe oxhydrile, carboxyle, aminogène ou mercaptique, comme'les alcools gras, les alcoyl-phénols, l'abiétinol, etc. On peut aussi employer des mélanges de plusieurs des substances précitées ayant un pouvoir dispersif ou autre.
Aux mélanges comprenant les constituants susindiqués on peut en outre ajouter des substances auxiliaires classiques, par exemple des sels, comme le sel de Glauber, du borax, du verre soluble, des ortho-, pyro- ou métaphosphates, etc., ainsi que des solvants, comme le cyclohexanol, le trichloréthylène, les éthers glycoliques, l'aminotriacétate de sodium, etc.
Les mélanges décrits se révèlent comme particulièrement avantageux lorsqu'il s'agit de produire des préparations à base de substances insolubles dans l'eau présentant un très fort pouvoir mouillant. Il en est ainsi par exemple lorsqu'on prépare des émulsions ou des solutions de phénols chlores ou non, d'extrait de pyrèthre, etc., comme on en utilise pour
<Desc/Clms Page number 4>
combattre les parasites. Les mélanges décrits sont aussi avantageusement utilisables pour d'autres usages, par exemple dans les industries des textiles, du cuir, du papier et du caoutchouc.
EXEMPLE 1.
A une solution de 1, 5 partie en poids du sel sodique de l'ester sulfurique acide de l'hexyl-heptyl-carbinol dans 30 parties en poids d'eau ajouter une solution de 4 parties en poids de parachloro-métacrésol dans 30 parties en poids d'une solution aqueuse à 10% de dibutyl-naphtalènesulfonate de sodium et 8 parties en poids de l'éther éthylique du polyéthylène-glycol, puis compléter le mélange à un total de 100 parties par adjonction d'eau. On obtient une préparation transparente qu'on peut diluer d'eau et qui, encore plus diluée au moyen d'eau, convient bien pour la conservation des textiles.
EXEMPLE 2.
Dans 100 parties en poids d'eau dissoudre 5 parties en poids du sel sodique de l'ester di-iso-octylique de l'acide sulfo-succinique, 10 parties en poids du sel sodique de l'oléyl-sarcosine, 3 parties en poids de trichloro-phénol et 8 parties en poids de butylène-glycol. La préparation obtenue convient très bien comme agent désinfectant sous forme de ses solutions aqueuses qui possèdent un très grand pouvoir mouillant.
EXEMPLE 3.
Mélanger ensemble 5 parties en poids du sel ammonique de l'ester di-iso-octylique de l'acide sulfo-succinique, 20 parties en poids du sel ammonique de l'acide dibutylnaphtalène-sulfonique, 2 parties en poids d'extrait de pyrè- thre, 2 parties en poids de polyéthylène-glycol, 20 parties en poids d'éther dibutylique et 1 partie en poids d'eau. La préparation obtenue peut être facilement diluée d'eau ;

Process for producing interesting preparations.
It has been found that interesting preparations can be produced which are advantageously useful in particular in the textile industry by mixing esters derived from dicarboxylic acids containing sulfonic groups and high molecular weight aliphatic alcohols or sulfuric esters derived from dicarboxylic acids. high molecular weight secondary aliphatic alcohols or the water-soluble salts of these esters, with other substances having a dispersive, solvent or detersive power and where appropriate with other substances.
<Desc / Clms Page number 2>
Suitable carboxylic esters for the production of these preparations are, for example, those of sulfomalonic, sulfo-succinic, sulfo-adipic or sulfo-phthalic acids with hexyl, octyl, dodecyl or undecyl alcohols, as well as with iso-octyl alcohol. , -ethyl-hexanol, or secondary alcohols such as hexylheptyl-carbinol, dioctyl-carbinol, dodecyl-undecyl-carbinol, etc. The esters in question can be obtained, for example, by sulfonation of carboxylic esters free of sulfonic groups or by esterification of carboxylic acids containing sulfonic groups by means of said alcohols, for example by the process described in Belgian Patent of May 6, 1931 N 379.608 .
Sulfuric esters of secondary aliphatic alcohols with high molecular weight, such as heptyl-octyl-carbinol, dodecyl-undecyl-carbinol, then those of alcohols which are formed by ketonization of aliphatic carboxylic acids, for example. even those which can be obtained by oxidizing paraffins, and by subsequent hydrogenation. Said compounds containing sulfonic groups can be employed in a particularly advantageous manner in the form of their salts, for example sodium, potassium, ammonium, amines or oxalkylamines.
Suitable substances having a dispersive, solvent or detersive power intended to be mixed with the said sulfo-carboxylic or sulfuric esters, for example sulfonic acids of alkylated aromatic hydrocarbons, for example propylated or butylated naphthalenesulfonic acids, then sulfonic acids high molecular weight aliphatics, for example oxy-octodecanesulfonic acid, sulfo-palmitic acid, as well
<Desc / Clms Page number 3>
as the condensation products of high molecular weight acids from oils or fats with aminoalkylsulphonic or carboxylic acids, finally turkish red oils or ordinary soaps.
As a second constituent in the present case, it is also possible to use sulfuric esters of fatty alcohols, for example those of lauric or oleic alcohols.
Substances with dispersive, solvent or detersive action which are often also suitable are products of the action of large quantities of ethylene oxide, for example of 3, 4.10 gram molecules or more of ethylene oxide on compounds having a hydrogen atom capable of reacting, for example in an oxhydril, carboxyl, aminogen or mercaptic group, such as fatty alcohols, alkyl-phenols, abietinol, etc. It is also possible to use mixtures of several of the aforementioned substances having dispersive or other power.
To the mixtures comprising the above-mentioned constituents it is also possible to add conventional auxiliary substances, for example salts, such as Glauber's salt, borax, water glass, ortho-, pyro- or metaphosphates, etc., as well as solvents. , such as cyclohexanol, trichlorethylene, glycol ethers, sodium aminotriacetate, etc.
The mixtures described prove to be particularly advantageous when it comes to producing preparations based on substances insoluble in water having a very high wetting power. This is the case, for example, when preparing emulsions or solutions of chlorinated or non-chlorinated phenols, of pyrethrum extract, etc., as used for
<Desc / Clms Page number 4>
fight parasites. The mixtures described can also advantageously be used for other uses, for example in the textile, leather, paper and rubber industries.
EXAMPLE 1.
To a solution of 1.5 parts by weight of the sodium salt of the acid sulfuric ester of hexyl-heptyl-carbinol in 30 parts by weight of water add a solution of 4 parts by weight of parachlorometacresol in 30 parts by weight of a 10% aqueous solution of sodium dibutylnaphthalenesulphonate and 8 parts by weight of polyethylene glycol ethyl ether, then make up the mixture to a total of 100 parts by adding water. A transparent preparation is obtained which can be diluted with water and which, further diluted with water, is well suited for the preservation of textiles.
EXAMPLE 2.
In 100 parts by weight of water dissolve 5 parts by weight of the sodium salt of the di-iso-octyl ester of sulfo-succinic acid, 10 parts by weight of the sodium salt of oleyl-sarcosine, 3 parts in weight of trichloro-phenol and 8 parts by weight of butylene glycol. The preparation obtained is very suitable as a disinfecting agent in the form of its aqueous solutions which have a very high wetting power.
EXAMPLE 3.
Mix together 5 parts by weight of the ammonium salt of the di-iso-octyl ester of sulfo-succinic acid, 20 parts by weight of the ammonium salt of dibutylnaphthalene-sulfonic acid, 2 parts by weight of pyre extract. - tea, 2 parts by weight of polyethylene glycol, 20 parts by weight of dibutyl ether and 1 part by weight of water. The preparation obtained can be easily diluted with water;
<Desc / Clms Page number 5>
aqueous solutions are very advantageously suitable as an agent for combating parasites.
