Abstract

Procedure for the continuous production of hexamethylene tetramine, characterized by starting from anhydrous ammonia and formaldehyde mixed with inert gases, at atmospheric pressure, with the introduction of these reagents in a saturated aqueous solution of hexamethylene tetramine and continuous extraction of a part of this saturated solution it is sent to a crystallization zone and then to a device for separating the crystals and the mother liquors and, furthermore, for carrying out the reaction at a temperature of 62 to 66º C, with washing of the gases escaping from the reaction medium, with an unsaturated aqueous solution of hexamethylenetetramine, so that at this temperature, the amount of water contributed by the washing solution, and the control of the development of the reaction is carried out by regulation of the reaction level, which remains constant.
