"PROCEDE DE FABRICATION D'ACIDE FORMIQUE LIBRE AVEC
FORMATION DE COMPOSES COMPLEXES NOUVEAUX.
L'invention concerne un procédé de fabri- cation d'acide fermique libre dans lequel sont fermés également des composés complexes nouveaux des matières de départ utilisées.
L'invention consiste, en principe, à humi difier des mélanges de boroformiates, en particulier
<Desc/Clms Page number 2>
de boroformiate de soude, et exacides, par exemple l'acide salicylique. Il se dégage alers lentement et, d'une manière continue, de l'acide formique libre avec formation simulta- née de boroxyborates, par exemple de borodisalicylates de soude,
On sait que l'acide fermique peut être libéré des formiates par l'addition d'acides d'une farce appropriée.
Mais, comme l'acide formique est lui-même un acide relative¯ ment fort, environ 12 fois plus fort que l'acide acétique, il faut empleyer des acides déjà très forts, par exemple des acides minéraux, pour mettre en liberté l'acide formique, à la température ordinaire. En tout cas, l'acide salicilyque, par exemple, n'agit pas ou n'agit pas d'une manière sensible sur le formiate de soude, à la température ordinaire, avec dégagemant d'acide formique.
Les conditions se présentent autrement, quand il y a possibilité de formation de composés complexes.
L'acide fermique (voir le brevet allemand Nr.
282809 du 21 Novembre 1913) est libéré des boroformiates, déjà à la température ordinaire, sous l'action d'exacides organiques, d'acides oxypolycarboxyliques etc..., avec for- mation de borates intra-complexes, sans qu'il soit néces- saire d'ajouter des acides minéraux.
Les exacides d'une teneur élevée en eau de cris- tallisation (par exemple l'acide tartrique et l'acide ci- trique) dégagent immédiatement, dans le mélange avec le bo- roformiate de soude, de l'acide formique libre, avec forma- tion des composés complexes correspondants. Si l'en emploie, au contraire, des exacides exempts d'eau de cristallisation (par exemple de l'acide salicylique), il se produit des mé- langes qui sont d'abord stables par eux-mêmes et qui dégagent seulement par humectation, par exemple déjà au seul contact de l'humidité de la peau, de l'acide fermique libre, avec
<Desc/Clms Page number 3>
formation simultanée des composés complexes correspondants, par exemple du borodisalicylate de soude.
D'après l'équation:
2 C6 H4 (OH) COOH plus HCOONa. B03 H3, 2H20 (acide salicylique)plus (boroformiate de seude) on obtient
EMI3.1
(borodisalicylate de soude)plus(acide formique)plus(malécules d'eau)
276 grs. d'acide salicylique et 166 grs. de boro- formiate de soude donnent 46 grs = 10,44% d'acide formique.
D'une manière correspondante, en obtient, par exemple, avec 1 molécule,d'acide salicylique et 1 molécule de borodormiate de soude, 7,56% d'acide formique ; avec1 molécule d'acide salicylique et 1 molécule de boroformiate de soude, on ob- tient 5,94% d'acide formique; \avec 1 molécule d'acide sali- cylique et 2 molécules de boroformiate de soude, on obtient 4,89% d'acide formique.
Au lieu de l'acide salicylique, on peut aussi empleyer d'autres exacides, par exemple l'acide p-oxybenzoique
Comme, d'après le nouveau procédé, l'acide fer- mique est dégagé en quantités réglables, et d'une manière con- tinue, sans addition d'acides minéraux, cet acide peut être empleyé dans tous les cas où 1 'on veut obtenir une action désinfectante, conservatrice, caustique, légèrement stimulan- te ou une action réductrice. On peut, par exemple, empleyer le mélange de boroformiate de soude et d'oxacide aux fins indiqués, sous forme de poudre à saupoudrer, et on fait en - suite agir de l'humidité (eau, vapeur d'eau, humidité de l'ai etc...) sur le mélange.

"PROCESS FOR MANUFACTURING FREE FORMIC ACID WITH
FORMATION OF NEW COMPLEX COMPOUNDS.
The invention relates to a process for the production of free fermic acid in which also novel complex compounds of the starting materials used are closed.
The invention consists, in principle, in moistening mixtures of boroformates, in particular
<Desc / Clms Page number 2>
of sodium boroformate, and exacids, for example salicylic acid. It is released slowly and continuously from free formic acid with simultaneous formation of boroxyborates, for example sodium borodisalicylates,
It is known that fermic acid can be liberated from formates by the addition of acids of a suitable filling.
But, since formic acid itself is a relatively strong acid, about 12 times stronger than acetic acid, it is necessary to use already very strong acids, for example mineral acids, to set free the formic acid, at room temperature. In any case, salicilyic acid, for example, does not or does not act appreciably on formate of soda, at room temperature, with release of formic acid.
The conditions are different, when there is the possibility of formation of complex compounds.
Fermic acid (see German patent Nr.
282809 of November 21, 1913) is released from boroformates, already at room temperature, under the action of organic exacids, oxypolycarboxylic acids etc ..., with the formation of intra-complex borates, without it being necessary to add mineral acids.
Exacids with a high water of crystallization content (for example tartaric acid and citric acid) immediately release, in the mixture with sodium boroformate, free formic acid, with formation of the corresponding complex compounds. If, on the contrary, it employs exacids free of water of crystallization (for example salicylic acid), mixtures are produced which are at first stable by themselves and which release only by moistening. , for example already only in contact with moisture in the skin, free fermic acid, with
<Desc / Clms Page number 3>
simultaneous formation of the corresponding complex compounds, for example sodium borodisalicylate.
According to the equation:
2 C6 H4 (OH) COOH plus HCOONa. B03 H3, 2H20 (salicylic acid) plus (boroformate of seude) we obtain
EMI3.1
(sodium borodisalicylate) plus (formic acid) plus (water malecules)
276 grs. of salicylic acid and 166 grs. of sodium boroformate give 46 grs = 10.44% of formic acid.
Correspondingly, obtained, for example, with 1 molecule of salicylic acid and 1 molecule of sodium borodormate, 7.56% formic acid; with 1 molecule of salicylic acid and 1 molecule of sodium boroformate, 5.94% formic acid is obtained; \ with 1 molecule of salicylic acid and 2 molecules of sodium boroformate, 4.89% formic acid is obtained.
Instead of salicylic acid, other exacids can also be used, for example p-oxybenzoic acid.
Since, according to the new process, fermic acid is evolved in controllable amounts, and continuously without the addition of mineral acids, this acid can be added in all cases where one. wants to obtain a disinfectant, preservative, caustic, slightly stimulating or reducing action. For example, the mixture of sodium boroformate and oxyacid can be used for the purposes indicated, in the form of a powder to be sprinkled on, and moisture (water, water vapor, moisture from the air) is then made to act. 've etc ...) on the mixture.
