Abstract

The hydrochlorination of 4, 4′-methylenedianiline, NH2C6H4CH2C6H4NH2 (MDA), in chlorobenzene to produce 4, 4′-methylenedianiline dihydrochloride,[ H3NC6H4CH2C6H4NH3] Cl2 (MDA· 2HCl) is an important reaction for the production of isocyanates, which are used to manufacture polyurethanes. This reaction is examined here. MDA is moderately soluble in chlorobenzene, whereas MDA· 2HCl is effectively insoluble. ...
