METHOD FOR PREPARING 2,5-DIAMINO-1,3,4-TRIAZOLE

摘要

FIELD: organic chemistry, chemical technology. ^ SUBSTANCE: invention relates to a method for synthesis of 2,5-diamino-1,3,4-triazole. Method involves interaction at heating of dithiourea with hydrogen peroxide in its concentration 24-26% and excess for 0.04-0.18 g-mole followed by decomposition of hydrogen peroxide excess with gaseous hydrogen sulfide up to onset of detecting sulfide ions in the solution. Proposed method provides preparing the end product with the yield 79-98% being without formation of colored by-side substances. ^ EFFECT: improved method of synthesis. ^ 1 tbl
