Quinacridone synthesis and method for producing intermediates thereof |
| abstract |
(57) [Abstract] [Objective] Synthesis of quinacridone and production of intermediate [Structure] Dimethylsuccinyl succinate is one or more aliphatic alcohols having at least two carbon atoms in the presence of an acidic catalyst under reaction conditions. In the presence or absence of an inert diluent, which blocks oxygen and transesterifies under pressure, wherein at least one of the two methoxy groups is replaced by an oxy group corresponding to the alcohol used. The above-mentioned method of transesterification and use of this method for the production of terephthalic acid and quinacridone. |
