| titleOfInvention | Production of 2,6-diaminobenzo-(1,2-d:4,5-d')-bisthiazole |
| abstract | PURPOSE: To obtain the titled compound in high purity in a relatively short reaction time without using organic solvent, by carrying out the oxidative cyclization of p-phenylenebis(thiourea) in sulfuric acid in the presence of bormine or hydrogen bromide. n CONSTITUTION: The objective compound can be produced by the oxidative cyclization of p-phenylenebis(thiourea) in sulfuric acid (preferably having a concentration of 55W100wt%) in the presence of bromine and/or hydrogen bromide (or a hydrobromide salt producing hydrogen bromide in sulfuric acid), preferably at 80W90°C for 3hr. The amount of sulfuric acid is preferably 5W9pts. wt. per 1pt.wt. of p-phenylenebis(thiourea). n USE: Intermediate for dyes and pigments, etc., or a raw material of 2,5-diamino-1,4- benzenethiol. n COPYRIGHT: (C)1986,JPO&Japio |
