| Abstract: | The method to synthesize 4 ,6-diaminoresorcinol dihydrochloride with resorcine as a starting material was proposed.Firstly, sulfonating resorcine obtained 2, 4, 6 -trisulfonateresorcine using a 30% fuming sulfuric acid, secondly, nitrating 2,4,6 -trisulfonateresorcine obtained 2 -sulfonic -4,6 -dinitroresorcine, then hydrolyzing the compound obtained 4,6-dinitroresorcine, finally, 4,6-dinitroresorcine was reduced to obtain a 4,6-diaminoresorcine with a purity of over 99%.The advantage of this synthetic method was estimated and the purity of compound of every step was analyzed. |
