Usage

Uses

Used in Oral Care Industry:
Stannous Acetate is used as an active ingredient in stannous oral care compositions for its antimicrobial and anti-plaque properties. It helps in maintaining oral hygiene and preventing dental caries.
Used in Chemical Industry:
Stannous Acetate is used as a precursor in the production of tin anode, Sn-Cu bimetallic nanoparticles, and high surface area tin oxide catalysts. It is also used as a Lewis acid catalyst for esterification and transesterification reactions, which are important in the synthesis of various organic compounds.
Used in Catalysis:
Stannous Acetate serves as an efficient catalytic system for carbon-hydrogen activation of the methoxy group of anisole in the presence of palladium(II) acetate. This reaction is crucial in the synthesis of various organic compounds and pharmaceuticals.

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.

Precursors for mixed metal oxide nanoparticles: Synthesis and characterization of μ-oxoalkoxides of some bivalent metals and their β-diketonates

New heterobimetallic derivatives of the type M{OAl(OPri) 2}2 (M = Sn, Pb, Cd) have been prepared by the reactions of M(OAc)2 with Al(OPri)3 in 1:2 molar ratio in hydrocarbon solvent (xylene/toluene) with the continuous liberation of isopropyl acetate. Furthermore, reactions of M{OAl(OPri) 2}2 (M = Ca, Pb, Cd) with β-diketones (acetylacetone, benzoyl acetone) have also been carried out to obtain modified derivatives. These new derivatives have been characterized by elemental analyses and spectroscopic [IR, NMR (1H, 13C, 27Al and 119Sn)] studies.

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.

Organotin chemistry. 16. Reactions of stannane with organic functional groups

The reactions of stannane with a variety of organic substrates have been studied. Benzaldehyde, acetone, nitrobenzene, and 2-nitropropane are reduced to benzyl alcohol, isopropyl alcohol, aniline, and isopropylamine, respectively. With boron trifluoride etherate and benzyl chloride, stannane undergoes halogen-hydrogen exchange, while with isopropylamine and acetic acid, it is decomposed catalytically into its elements. Tetrakis(2-cyanoethyl)tin is formed by the addition of stannane to acrylonitrile. Stannane did not react with the following: (a) ethyl acetate, (b) methyl acrylate, (c) aniline, (d) triethylamine, (e) dimethylacetamide, and (f) N-ethylacetamide. The results obtained with stannane are for the most part analogous to those reported for the corresponding organotin hydrides.

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.
