Dibutyltin diacetate Chemical Properties,Usage,Production

Chemical Properties

clear pale yellow to yellow liquid

Uses

PU catalyst, RTV silicone rubber

Uses

As as stabilizer in chlorinated organics, and as a catalyst for condensation reactions.Di-n-butyltin diacetate is used as a stabilizer for polyvinyl chloride. It acts as a catalyst for the preparation of silicone and urethane foams. Further, it is used as a curing agent for silicone elastomers. In addition to this, it is used as a precursor for thin-film tin(IV) oxide gas sensing materials by laser-assisted chemical vapor deposition.

General Description

Clear yellow liquid.

Air & Water Reactions

Forms white precipitate in water. Insoluble in water.

Reactivity Profile

Dibutyltin diacetate is stable under normal laboratory conditions. Dibutyltin diacetate may react with oxidizers. . Strongly reactive with many other groups. Incompatible with acids and bases. Organometallics are good reducing agents and therefore incompatible with oxidizing agents.

Fire Hazard

Dibutyltin diacetate is combustible.

Safety Profile

Poison by ingestion and intravenous routes. Experimental reproductive effects. Combustible when exposed to heat or flame; can react with oxidizing materials. To fight fire, use water, foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes. See also TIN COMPOUNDS.
