HEXAMINE PRODUCT / PROCESS OVERVIEW


“Hexamine” (produced by reaction between Ammonia and Aqueous Formaldehyde) is the short form of Hexa Methylene Tetra Amine (C6H12N4). It has also other names like Urotropin, Methenamine, Aminoform, Crystamin, Formin, Uritone etc. Hexamine is a solid crystalline or granular white powder generally having an average particle size of 40 to 60 meshes per linear inch. It is soluble in water, spirit, chloroform etc. Hexamine is the amino – analogue of Trioxane. In the liquid phase process Hexamine is produced by reaction of Aqueous Formaldehyde (AF 37) and anhydrous Ammonia in liquid forms. In a slightly different process vapour phase Ammoniation of Formaldehyde can also be carried out. A basic flow diagram is given below :
