Title:
DIAZOTIZATION OF AMINE
Document Type and Number:
Japanese Patent JPS61140557
Kind Code:
A
Abstract:
Amines which are sparingly soluble in water are diazotised by first preparing a melt or solution of said amines and then precipitating them from the melt or a solution in an organic solvent by adding water, and then diazotising the resultant suspension. In this procedure, the reaction times are appreciably shorter than those of conventional processes.
