Method for synthesizing 2,5-diaminohydroquinone dihydrochloride

The invention discloses a method for synthesizing 2,5-diaminohydroquinone dihydrochloride. The method for synthesizing 2,5-diaminohydroquinone dihydrochloride includes the steps that under normal temperature, raw materials including chloranil and a reaction solvent are added into a reaction container, stirring is conducted, ammonium hydroxide is dropwise added, after dropwise addition is completed, temperature is increased to 50-80 DEG C, an ammonolysis reaction is conducted for 2-8 h, then reaction liquid is subjected to after-treatment, and finally an intermediate which is 2,5-diamino-3,6- dichloro-benzoquinone is obtained; 2,5-diamino-3,6-dichloro-benzoquinone, water and Pd/C are added into a reaction kettle for a reduction reaction for 1-8 h at the temperature of 40-80 DEG C and underhydrogen pressure of 0.1-0.6 MPa, then reaction liquid is subjected to after-treatment, and finally the 2,5-diaminohydroquinone dihydrochloride is obtained. Reaction technology parameters are easy tocontrol, energy consumption is low, no toxic side products are generated, the yield is good, purity is high, and industrial feasibility is high.
