Paragraph 0011; 0012; 0014; 0016; 0018; 0020, (2018/06/04)
The invention relates to a method for synthesizing 2-methyl-1,2-propylene diamine. According to the method, 2-amino-2-methyl-1-propyl alcohol is adopted as a raw material, and a cobalt catalyst and aids are combined to form a catalyst. The method has the advantages that the reaction pressure is low, the target product, namely the 2-methyl-1,2-propylene diamine, is high in selectivity, and the like, and relatively high industrial production values can be made.

[PROBLEM TO BE SOLVED]: To provide a method for synthesizing 1,1-disubstituted ethylenediamine (III) safely and economically, and therefore making possible a industrial production. [SOLUTION]: The method for producing the intermediate shown by the general formula (II) characterized by reacting ketones shown by the general formula (I) , nitromethane and ammonia, next producing 1,1-disubstituted ethylenediamine shown by the general formula (III) by catalytic hydrogenation's reaction.(Wherein R1, R2 are at the same time or independently alkyl of C1-6, trifluoromethyl, or cycloalkyl of 3-10 formed by R1 and R2 and the carbon of the root.)
