As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 94-60-0 name is Dimethyl cyclohexane-1,4-dicarboxylate, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below. 94-60-0
Comparative Examples 1-3Using the same procedure as in Examples 7-9, DMCD was hydrogenated using a commercially available copper chromite catalyst. Analysis of the reactor effluent was carried out by gas chromatography and the results are shown in Table 3 as area %.
