Abstract

L'invention est relative à un procédé pour séparer le gaz chlorhydrique de solutions de chlorhydrates d'amine. Selon l'invention, tout en faisant passer un courant de gaz inerte, on chauffe entre 100 et 250 degrés C, dans un solvant organique inerte largement apolaire, un chlorhydrate d'amine dont le constituant amine est formé d'alkylamines tertiaires, d'aryldialkylamines tertiaires, d'aryl-alkylamines secondaires, d'alkylarylamines primaires ou de mélanges de celles-ci qui contiennent de 14 à 36 atomes de carbone dans les chaînes latérales reliées à l'azote, ces chaînes comprenant au maximum un groupe méthyle relié à l'azote et au minimum un radical aliphatique contenant au moins 6 atomes de carbone, lié à l'azote. L'invention permet d'obtenir sous forme libre l'amine utilisée au départ sous forme de chlorhydrate
