PROCEDE DE FABRICATION DE SELS DE DIAMMONIUM DIFURANIQUES OU DE DIAMINES DIFURANIQUES ET COMPOSES OBTENUS.

摘要

A method for producing difuran diammonium salts or "DADF" having formula (a). The method is characterized in that the two reactions (1) and (2) are carried out successively by mixing furfurylamine with HX acid to cause protonation of the amine (1) and by placing the product of reaction (1) in the presence of a carbonyl compound of formula (b) in an acidic medium to cause condensation (2) and produce the DADF. Passage through an alkaline medium allows the corresponding diamines to be obtained.
