Corrosion in the Ammonolysis Of Aliphatic Chlorides^⋆ Available to Purchase

Corrosion data are presented relating to a process for manufacture of methallylamine by the high pressure liquid phase ammonolysis of methallyl chloride. Relative corrosion resistance of a number of alloys has been determined for the two most severely corrosive process streams encountered, one involving essentially an anhydrousolution of ammonium chloride in liquid ammonia and the other a mixture containing methallylamine and unreacted aliphatic chloride. The two systems have been found to have similar corrosion characteristics. Study of other combinations of amines and aliphatic chlorides has revealed such combinations to be generally corrosive to carbon steel and other common alloys under moderately high temperature conditions.
