    摘要: A new process for the production of 1-amino-1-methyl-3(4)-cyanocyclohexane (AMCC), an intermediate for the manufacture of 1-isocyanato-1-methyl-3(4)-isocyanatomethylcyclohexane. In this process, 4(5)-cyano-1-methylcyclohexene is reacted with excess hydrogen cyanide in the presence of aqueous sulfuric acid to form 1-formamido-1-methyl-3(4)-cyanocyclohexane which is then selectively hydrolyzed in an acidic medium to form AMCC.
