procédé de solidification d'acide lactique pur.. On connaît un procédé de solidification de l'acide lacti- ' que pur, qui est basé sur le traitement à froid de l'acide lac- tique pur avec matières pectiques comme adsorbant. On connaît également un procédé de solidification de l'acide lactique pur qui consiste dans le traitement de matières mucilagineuses et de matières foisonnantes, végétales et en poudre, comme adsor- beurs. Quelques-unes seulement de ces matières mucilagineuses et foisonnantes existent - et encore en petites quantités - dans le pays ; la plus grande partie doit en être importée. Il en résulte une augmentation notable des frais de fabrication de l'acide lactique solidifié.
Le problème se posait donc, de trouver, en dehors des ma- tières mucilagineuses et foisonnantes mentionnées, un adsorbant qui puisse donner l'effet voulu et soit susceptible de solidi- fier sans difficulté l'acide lactique pur. ceci était d'autant plus nécessaire qu'il s'est démontré entretemps que l'acide lac-
<Desc/Clms Page number 2>
tique solidifié peut être employé sous de nombreux rapports avec grand avantage et ce, non seulement pour l'apprêt, le finissage des tissus, mais aussi comme agent auxiliaire de cuisson dans la boulangerie et dans d'autres applications importantes. Il est évidemment doublement important que la solidification de l'acide lactique soit faite à un prix aussi bas que possible.
Les matières mucilagineuses et foisonnantes employées dans le procédé connu mentionné coûtent plus de 80 % de l'acide lactique lui-même.
Il a été trouvé, conformément à l'invention, que, pour la solidification de l' acide lactique pur, on peut employer de l'amidon, non pas à la température ordinaire, mais à une température comprise entre 100 et 110 C. On obtient alors un acide lactique pur solide, en forme de poudre ou en forme friable, qui possède les mêmes propriétés que l'acide lactique obtenu par les procédés connus de solidification.
A titre d'exemple, on mél ange 50 parties d'amidon sec en poudre (amidon de pommes de terre, de froment ou de seigle) à 50 parties d' acide lactique pur contenant 80 % d'acide et 20 % d'eau. Apres que l'acide lactique a monté, le mélange, sans aj ou te d'eau, est chauffé à 100 - 110 C. , et il se forme une mas se pul vérul e nte uniforme, que l'on peut emballer dans des sacs de papier ou de tissu, ou dans des bottes de carton ou des caisses.

A process for solidifying pure lactic acid. A process for solidifying pure lactic acid is known, which is based on the cold treatment of pure lactic acid with pectic materials as an adsorbent. A process for the solidification of pure lactic acid is also known which consists in the treatment of mucilaginous materials and of swelling materials, vegetable and powder, as adsorbers. Only a few of these abundant mucilaginous matters exist - and still in small quantities - in the country; most of it must be imported. This results in a notable increase in the cost of manufacturing solidified lactic acid.
The problem therefore arose of finding, apart from the mucilaginous and abundant substances mentioned, an adsorbent which can give the desired effect and is capable of solidifying pure lactic acid without difficulty. this was all the more necessary since it has been demonstrated in the meantime that the acid lac-
<Desc / Clms Page number 2>
Solidified tick can be employed in many respects with great advantage, not only for sizing, finishing fabrics, but also as a baking aid in baking and other important applications. It is obviously doubly important that the solidification of lactic acid be done at as low a cost as possible.
The mucilaginous and swelling materials employed in the known method mentioned cost over 80% of the lactic acid itself.
It has been found, in accordance with the invention, that, for the solidification of pure lactic acid, starch can be used, not at room temperature, but at a temperature between 100 and 110 C. then obtains a pure solid lactic acid, in powder form or in friable form, which has the same properties as lactic acid obtained by known solidification processes.
For example, 50 parts of dry powdered starch (potato, wheat or rye starch) are mixed with 50 parts of pure lactic acid containing 80% acid and 20% water. . After the lactic acid has risen, the mixture, without adding water, is heated to 100 - 110 C., and a uniform pulverulent mass forms, which can be packed in containers. paper or cloth bags, or in cardboard bundles or crates.
