Abstract

Method of making 2,3- dihydrogen -1,4,5,8- tetrahydroxy -9,10 anthryl diketone comprises: mixing 5-45% of fumed acid, 1,8- dihydroxy anthryl quinone and 1-3 equivalent of boric acid according to the equivalent of 1,8- dihydroxy anthryl quinone, adding nitric acid drop by drop to nitrify 1,8- dihydroxy anthryl quinone to produce 1,8- dihydroxy -4,5- dinitro anthryl quinone, washing the mixture with solvent and extracting the product with a solvent containing dimethyl amide at -10-50 deg.C; adding 60-90% of sulfuric acid and iron powder to reduce 1,8- dihydroxy -4,5- dinitro anthryl quinone into 1,8- dihydroxy -4,5- diamino anthryl quinone at 60-120 deg.C; adding alkaline solution with 5-25% oforganic solvent and 0.1-0.25 mole of sodium hydrosulfite to reduce 1,8- dihydroxy -4,5- diamino anthryl quinone into 2,3- dihydrogen -1,4,5,8- tetrahydroxy -9,10- anthryl diketone.
