Description
Maurice Willemyns, Grenoble (Isère, France), est mentionné comme étant l'inventeur La présente invention a pour objet un procédé de fabrication d'un produit de blanchiment à chlore actif ayant des propriétés bactéricides.
Il est connu d'utiliser des composés à chlore actif comme produit de blanchiment ou de désinfection. On entend par composés à chlore actif, les produits contenant au moins un atome de chlore fixé soit à un atome d'oxygène, soit à un atome d'azote et pou vant agir dans des opérations d'oxydation.
De tels produits sont, par exemple, les chloramines, les chlor- amides, les chlorimides et les chloranilides. Les hypo- chlorites minéraux, tels que, par exemple, l'hypochlo- rite de sodium ou l'hypochlorite de calcium, sont éga lement des sources bien connues de chlore actif.
Toutefois, tous ces composés connus présentent l'inconvénient de ne pas être stables lorsqu'ils sont incorporés à des préparations commerciales ou sim plement lorsqu'ils sont stockés, de sorte que leur em ploi en tant que produit de blanchiment est très limité.
Le but du procédé faisant l'objet de la présente invention est d'obtenir un nouveau composé à chlore actif stable, pouvant être utilisé comme produit de blanchiment et possédant, en outre, un fort pouvoir bactéricide.
Ce procédé est caractérisé par le fait que l'on fait réagir un agent chlorurant sur un composé d'ammonium quaternaire, de formule
EMI0001.0033
de manière à obtenir un composé de formule
EMI0001.0035
formules dans lesquelles A- est un anion et dans lesquelles Rl, R2, R3 et R4 représentent des restes aliphatiques, hétérocycliques ou aromatiques, ou dans lesquelles trois au plus de ces restes forment avec l'atome d'azote quaternaire un hétérocycle.
Comme on le sait, les agents tensioactifs du type ammonium quaternaire présentent des propriétés bac téricides ; ils sont utilisés couramment pour le lavage et la désinfection dans les domaines médical et ali mentaire.
Or, nous avons constaté que le composé à chlore actif obtenu par le procédé suivant l'invention, pos sède une grande efficacité comme agent de blanchi ment. De plus, les propriétés bactéricides propres à l'ammonium quaternaire mentionnées ci-dessus, sont conservées. Ainsi un tel produit peut être avantageu sement utilisé comme agent de blanchiment bactéri cide. Enfin, un tel produit est très stable.
Comme agent chlorurant, on peut utiliser, par exemple, un hypochlorite minéral ou encore le chlore pur. Quant au composé d'ammonium quaternaire, ce peut être un sel d'ammonium quaternaire ou encore un hydroxyde d'ammonium quaternaire.
Le produit obtenu par le procédé suivant l'inven tion se présente sous forme solide, pàteuse ou liquide suivant le composé d'ammonium quaternaire utilisé. Il peut être séparé du milieu réactionnel par filtration ou simplement par décantation.
Les exemples suivants indiquent quelques-unes des manières de mettre en oeuvre le procédé suivant l'invention <I>Exemple 1</I> On dissout 37,6 g (0,1 mole) de bromure de tétra- décyl-triméthyl-ammonium dans 200 cm3 d'eau.
La solution est ensuite refroidie à 5o C, puis elle est addi tionnée d'une solution d'hypochlorite de sodium con tenant 0,12 équivalent d'ions hypochlorite. Un solide blanc précipite ; il est filtré, lavé à l'eau puis séché sous pression réduite.
L'hypochlorite obtenu contient environ 11 % de chlore actif. Cette teneur est mesurée par oxydimétrie. On opère avec l'anhydride arsénieux, en présence de bicarbonate de sodium ;
l'excès d'anhydride est en suite déterminé volumétriquement à l'aide d'une solu tion de bromate de potassium, en présence d7indigo- carmin. Il est à remarquer que la méthode de titrage habituelle du chlore actif, par iodométrie ne s'appli que pas à ces analyses ; en effet, il a été observé que la présence de l'agent tensioactif empêchait la colo ration de l'empois d'amidon par l'iode.
<I>Exemple 2</I> On prépare une solution contenant 32,8 g (0,1 mole) de bromure de lauryl-pyridinium dans 250 em3 d'eau. L'hypochlorite d'ammonium quaternaire pré cipite par l'action d'une solution d'hypochlorite de calcium contenant 0,15 équivalent d'ions hypochlo- rite.
<I>Exemple 3</I> On prépare une solution de 50g d'un mélange de bromure d'alkyl-triméthyl-ammonium dans 250cmg de NaOH n/1, que l'on sature ensuite de chlore entre 0o et 10o C. Le mélange d'hypochlorites précipite au fur et à mesure de l'introduction.
<I>Exemple 4</I> On prépare une solution d'hydroxydes d'alkyl-tri- méthyl-ammonium en faisant passer une solution aqueuse du mélange des bromures sur un échangeur d'anions. On sature ensuite cette solution de chlore jusqu'à précipitation complète du mélange d7hypo- chlorites.
Maurice Willemyns, Grenoble (Isère, France), is mentioned as being the inventor. The present invention relates to a process for manufacturing an active chlorine bleach product having bactericidal properties.
It is known to use compounds containing active chlorine as a bleach or disinfect product. The term “active chlorine compounds” means products containing at least one chlorine atom attached either to an oxygen atom or to a nitrogen atom and able to act in oxidation operations.
Such products are, for example, chloramines, chloramides, chlorimides and chloranilides. Inorganic hypochlorites, such as, for example, sodium hypochlorite or calcium hypochlorite, are also well known sources of active chlorine.
However, all these known compounds have the drawback of not being stable when they are incorporated into commercial preparations or simply when they are stored, so that their use as a bleach product is very limited.
The aim of the process forming the subject of the present invention is to obtain a new compound with stable active chlorine, which can be used as a bleaching product and which also has a strong bactericidal power.
This process is characterized by the fact that a chlorinating agent is reacted with a quaternary ammonium compound, of formula
EMI0001.0033
so as to obtain a compound of formula
EMI0001.0035
formulas in which A- is an anion and in which Rl, R2, R3 and R4 represent aliphatic, heterocyclic or aromatic residues, or in which three at most of these residues together with the quaternary nitrogen atom form a heterocycle.
As is known, surfactants of the quaternary ammonium type exhibit bac tericidal properties; they are commonly used for washing and disinfection in the medical and food fields.
Now, we have found that the active chlorine compound obtained by the process according to the invention has great effectiveness as a bleaching agent. In addition, the bactericidal properties specific to quaternary ammonium mentioned above are preserved. Thus, such a product can be advantageously used as a bacterial bleaching agent. Finally, such a product is very stable.
As chlorinating agent, it is possible to use, for example, an inorganic hypochlorite or else pure chlorine. As for the quaternary ammonium compound, it can be a quaternary ammonium salt or else a quaternary ammonium hydroxide.
The product obtained by the process according to the invention is in solid, pasty or liquid form depending on the quaternary ammonium compound used. It can be separated from the reaction medium by filtration or simply by decantation.
The following examples indicate some of the ways of carrying out the process according to the invention <I> Example 1 </I> 37.6 g (0.1 mole) of tetradecyl-trimethyl-ammonium bromide are dissolved. in 200 cm3 of water.
The solution is then cooled to 5 ° C., then it is added to a solution of sodium hypochlorite containing 0.12 equivalent of hypochlorite ions. A white solid precipitates; it is filtered, washed with water and then dried under reduced pressure.
The hypochlorite obtained contains approximately 11% of active chlorine. This content is measured by oxidimetry. The operation is carried out with arsenious anhydride in the presence of sodium bicarbonate;
the excess anhydride is subsequently determined volumetrically using a solution of potassium bromate, in the presence of indigo-carmine. It should be noted that the usual titration method of active chlorine, by iodometry does not apply to these analyzes; in fact, it has been observed that the presence of the surfactant prevents the colouration of the starch paste by iodine.
<I> Example 2 </I> A solution is prepared containing 32.8 g (0.1 mol) of lauryl-pyridinium bromide in 250 em3 of water. Quaternary ammonium hypochlorite precipitates by the action of a solution of calcium hypochlorite containing 0.15 equivalent of hypochlorite ions.
<I> Example 3 </I> A solution of 50g of a mixture of alkyl-trimethyl-ammonium bromide in 250cmg of n / 1 NaOH is prepared, which is then saturated with chlorine between 0o and 10o C. The mixture of hypochlorites precipitates as the introduction progresses.
<I> Example 4 </I> A solution of alkyl-tri-methyl-ammonium hydroxides is prepared by passing an aqueous solution of the mixture of bromides through an anion exchanger. This solution is then saturated with chlorine until complete precipitation of the hypochlorite mixture.
