Dibutyltin diacetate Usage And Synthesis
Chemical Propertiesclear pale yellow to yellow liquid
UsesPU catalyst, RTV silicone rubber
UsesAs 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 DescriptionClear yellow liquid.
Air & Water ReactionsForms white precipitate in water. Insoluble in water.
Reactivity ProfileDibutyltin 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 HazardDibutyltin diacetate is combustible.
Safety ProfilePoison 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.
