ECOLOGICAL ASPECTS OF INDANTHRONE PRODUCTION.

The authors describe certain procedures for diminishing the harmful effects of indanthrone (I) production on the environment. The purpose of this work was to develop an ecologically acceptable technology for production of Vat Blue 0, with shortening and intensification of stages of low efficiency. It was found that the determining factor in production of Vat Blue 0 is the ratio of the solvent to potassium hydroxide. Melt mobility is ensured by the KOH:H//2O ratio (KOH of 88 mass % concentration is in the liquid phase even at 100 degree ). The highest indanthrone yield is attained at 1:0. 17 ratio of KOH to triethylene glycol (TEG). At 1:1 component ratio indanthrone is not formed, while at 1:05 ratio the yield is not high.
