Molecular Weight: 228.31
CAS NO: 102-08-9

White powder. The density is 1.32. A little bitter, flammability, almost no poison. Soluble in alcohol, diethyl ether, acetone, cyclohexanone, tetrohydrofuran, partly soluble in all PVC plasticizers, insoluble in water and CS2. Soluble in alkali solutions and precipitation from acid solutions

Source of Preparation

It is prepared by reacting aniline, carbon disulfide, ethanol and sulfur.

Medium-speed vulcanization accelerator. Synergizes with sulfur donor to boost vulcanization when used in NR and SBR. Need zinc oxide to be effective. Used as secondary accelerator in CR vulcanization and EPDR vulcanization system. Used in latex products, cables and general industrial products. It's critical temperature is 80℃, so could be used as raw materials for pharmaceutical, dye and the test reagent for Os and Rh.This substance is a natural latex, chloroprene latex and rubber product's vulcanization accelerator. It is used in the manufacturing of industrial products such as vulcanized capsules, water molds, wires and cables, rubber shoes, etc. It can also be used as a heat stabilizer for polyvinyl chloride soft products (with an addition amount of 0.2 - 0.5 parts).

Dissolution situation

0.01g/100ml at 19°C. Dissolves in tetrahydrofuran, cyclohexanone, acetone, alcohols, ether. Slightly soluble in various plasticizers used in polyvinyl chloride. Insoluble in water and carbon disulfide.

25kg plastic woven bag, paper with plastic film bag, kraft paper bag.

The product should be stored in the dry and cooling place with good ventilation, avoiding exposure of the packaged product to direct sunlight The validity is 1 year.
