THE INFLUENCE OF FACTORS ON PROCESS FOR THE PREPARATION OF SULFUR POLYMERS

Abstract

   Study the effect of input factors (volumetric ratio of carbon disulfide /elemental sulfur, number of washings, reaction temperature and reaction time) on the synthesis of sulfur polymer from elemental sulfur and carbon disulfide solvent during elemental sulfur melting. Elemental sulfur concentrations are 81,0% Wt, carbon disulfide concentration is 76,14% wt, volumetric ratio CS2/ S ranged from 0,875/1.0 to 1,5/1,0. Reaction temperatures kept between 140°C and 200°C. The response time lasts from 2.0 hours to 5.0 hours. At this condition, the reaction yield is 70 - 90% of the theory.
