Description
Procédé pour la fabrication de formaline. La présente . invention a pour objet un procédé pour la fabrication de forrnaline, d'après lequel on fait réagir a chaud de l'oxyde de carbone sur de l'hydrure de cal cium. On peut recueillir la formaldéhyde ob tenue dans de l'eau. Voici, à titre d'exemple, de quelle ma nière on peut s'y prendre pour la mise en couvre de ce procédé: Environ 10 gr d'hydrure <B>(le</B> calcium CaH_ placés clans un tube en verre sont chauffés dans un four îi combustion. On fait passer lentement un courant d'oxyde (le carbone <B>(</B>CO) sur l'hydrure (le calcium chauffé. On fait passer les gaz quittant le tube par un flacon laveur contenant de l'eau et on ob tient une solution faible (le formaline. On peut supposer que ce corps se forme d'après l'équation suivante: Ca H_ -;- CO -: - Ca + CIL O. La présence (le l'alcléliyde formique petit étre reconnue par les réactions caractéristi- ques telles due, par exemple, l'odeur, la ré duction d'une solution médicinale de nitrate d'argent, la formation d'une matière colo rante bleue avec la dimét.nylaniline.
