Usage

Description

Antimony(III) acetate is the compound of antimony with the chemical formula of Sb(CH3CO2)3. It is a white powder, is moderately water-soluble, and is used as a catalyst in the production of polyesters.

Uses

Antimony(III) acetate is a catalyst used in the production of synthetic fibers.Antimony(III) acetate was used in the one-pot three-component synthesis of multigram quantities of 1-amidoalkyl-2-naphthols from the condensation between aldehydes, 2-naphthol and acetamide under solvent-free conditions at ambient temperature.journals.sagepub.com

Preparation

It can be prepared by the reaction of antimony(III) oxide with acetic acid:Sb2O3+ 6 CH3CO2H → 2 Sb(CH3CO2)3+ 3 H2O

Safety Profile

Mildly toxic by ingestion. A skin and eye irritant. Mutation data reported. See also ANTIMONY COMPOUNDS. When heated to decomposition it emits acrid smoke and irritating fumes.
