2-(Morpholinothio)benzothiazole Usage And Synthesis

Description

This rubber vulcanization accelerator is used as a chemical in the rubber industry, especially in the production of synthetic rubber articles. Is contained in the "mercapto mix". As a corrosion inhibitor, it can be found in cutting fluids or in releasing fluids in the pottery industry. It induces mainly delayed-type hypersensitivity, but a case of immediate-type hypersensitivity was reported in a dental assistant.

Chemical Properties

Buff to brown flakes; sweet odor. Insoluble in water; solublein benzene, acetone, methanol.

Uses

Delayed-action vulcanization accelerator.

Contact allergens

This rubber vulcanization accelerator belongs to the mercaptobenzothiazole-sulfenamide group. It is used as a chemical in the rubber industry, especially in the production of synthetic rubber articles. It is contained in “mercapto mix.” As a corrosion inhibitor, it can be found in cutting fluids or in releasing fluids in the pottery industry. It induces mainly delayed-type hypersensitivity, but a case of immediate-type hypersensitivity was reported in a dental assistant.

Safety Profile

Poison by intraperitoneal route.Moderately toxic by ingestion. Questionable carcinogenwith experimental neoplastigenic data. Experimentalteratogenic effects. An eye irritant. Mutation datareported. When heated to decomposition it emits very toxic fum
