PROCEDE DE FABRICATION DE SELS DE TETRA-AMMONIUM TETRAFURANIQUES OU DE TETRA-AMINES TETRAFURANIQUES ET COMPOSES OBTENUS.

摘要

A method for producing tetrafuran tetra-ammonium salts or "TATF" having formula (a). The method is characterized in that the following two reactions are performed successively (1) and (2) 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 dicarbonyl compound (b) in an acidic medium to cause condensation (2) and produce the tetrafuran tetra-ammonium salts.
