1,3-Diphenyl-2-thiourea - Uses and synthesis methods

chemical properties

grayish white powdery crystals. Soluble in ethanol, ether, completely insoluble in water and carbon disulfide. Soluble in dimethylformamide, acetone, chloroform, benzene.

use

1. Used as a rapid vulcanization accelerator for natural latex and neoprene latex

2. Used as a reagent for the determination of osmium and ruthenium, a sulfur slurry accelerator, and also used in the dye industry

3. this product is an accelerator with fast vulcanization speed. it is mainly used for natural latex and neoprene dairy products. it can also be used for manufacturing vulcanized capsules, water tires, tire repair rubber, wires and cables, industrial products, rubber shoes, etc. This product can also be used as a heat stabilizer for emulsion PVC, especially for soft products, with a general dosage of 0.2-0.5%. It will not color plastic products, but cannot prevent products from changing color by light. It cannot be used with lead and cadmium stabilizers, otherwise it will cause discoloration of the product. Diphenylthiourea is also an intermediate of medicine and dyes. It is used to produce indigo, methyl indigo, sulfide dyes, flotation agents, and anti-acid agents. This product is a chemical reagent for the determination of osmium and ruthenium. The toxicity of this product is low. The LD50 injected intraperitoneally in mice is 400 mg/kg, and the oral LD50 of rats is 2000 mg/kg. It has no carcinogenicity.

production method

It is obtained by condensation of aniline and carbon disulfide. Kg/ton aniline 900 carbon disulfide 420
