Uses

Different sources of media describe the Uses of 638-39-1 differently. You can refer to the following data:
1. STANNOUS ACETATE is used in stannous oral care compositions.
2. Tin(II) acetate is used as a precursor in the production of tin anode, Sn-Cu bimetallic nanoparticles, high surface area tin oxide catalysts. It acts as Lewis acid catalysts for the esterification and transesterification reactions. It serves as an efficient catalytic system for carbon-hydrogen activation of methoxy group of anisole in presence of palladium(II) acetate. It plays an important role in stannous oral care compositions.

Hazard

Toxic by ingestion.

Crystal structure and chemical bonding in tin(II) acetate

Tin(II) acetate was prepared and its crystal structure was solved from X-ray powder diffraction data. Tin(II) acetate adopts a polymeric structure consisting of infinite Sn(CH3COO)2 chains running along the c-axis which are packed into groups of four. The acetate groups bridge the Sn atoms along the chains. The Sn atoms are asymmetrically surrounded by four oxygen atoms with two short Sn-O distances (2.170(6), 2.207(6) ?) and two longer ones (2.293(7), 2.372(8) ?). The coordination environment of the Sn atoms is completed up to a strongly distorted trigonal bipyramid SnO4E by the sterically active lone electron pair E. The coordination environment of the Sn atoms is virtually identical for Sn(CH3COO)2 in the gaseous and solid phase: the two short Sn-O bonds and the lone electron pair are located in the equatorial plane of the trigonal bipyramid and the two longer Sn-O bonds are directed towards the apical vertexes. Localization of the lone electron pair on Sn(II) was confirmed by electron localization function (ELF) analysis. The polymeric nature of the tin(II) acetate crystal structure was confirmed by a MALDI-TOF experiment.

Low melting point tin salt of carboxylic acid and method for producing the same

The present invention provides a low melting point tin salt of aliphatic monocarboxylic acid obtained by a process comprising, reacting an aliphatic monocarboxylic acid having 4 to 30 carbon atoms or its salt and an inorganic tin compound so as to prepare a tin salt of aliphatic monocarboxylic acid, and bringing the tin salt in contact with an oxygen supplying substance.

Method for the preparation of anhydrous tin-(IV)-carboxylates

A method is disclosed for the preparation of anhydrous tin-(IV)-carboxylate. Metallic tin or Sn-(II)-acetate is reacted with an excess of acetic acid anhydride under agitation and at temperatures of 50° to 150° C. Oxygen is passed through the reaction mixture or an oxygen yielding agent is added thereto. The tin-(IV)-acetate thus formed, which is useful, per se, is separated from the reaction mixture and further reacted with a carboxylic acid with more than four carbon atoms or an acid anhydride corresponding to said carboxylic acid. The reaction is carried out at temperatures of about 80° to 150° C. and the liberated acetic acid anhydride or acetic acid is removed by distillation under vacuum.
