Abstract:Right dimethyl carbonate in 4-methyl-cyclohexane-amine synthesis of N - (4-methyl-cyclohexane) - carbamate the reaction of study results showed that the best conditions were as follows : the amount of catalyst n (magnesium chloride) : n (4-methyl-cyclohexane - amine) -6 : 100, the reaction temperature was 60℃ reactant ratio of n (4-methyl-cyclohexaneamine) : n (DMC) - 1 : 4, reaction time 11 h. The highest yield was 35.3 %, GC analysis of its purity was 89.2 %, the latter dealing with simple, low environmental pollution.
Keywords:4-methyl-cyclohexylisocyanate  dimethylcarbonate  synthesis  studyofsynthesizingconditions
