Patent

CA 2206763

Amines which are solid at ambient temperature and pressure are liquified by reacting those amines with a derivatizing agent represented by the formula XY in which X represents a halide or sulfonate group and Y represents an alkyl group, a cycloalkyl group, an alkoxyalkyl group or an aryl group. The amine and derivatizing agent are reacted at temperatures of from about 50 to about 250°C in amounts such that the molar ratio of derivatizing agent to amine groups is from about 0.25:1 to 8:1.

Liquéfaction d'amines solides à la température et à la pression ambiantes, par réaction de ces amines avec un agent dérivateur représenté par la formule XY dans laquelle X représente un groupe halogénure ou sulfonate et Y un groupe alkyle, cycloalkyle, alcoxyalkyle ou aryle. On fait réagir l'amine et l'agent dérivateur à une température comprise entre 50 et 250 degrés C environ, dans un rapport molaire agent dérivateur/groupes amines se situant dans une plage de 0,25/1 à 8/1 environ.
