Asahi Kasei Chemicals Assigned Patent for Dialkyl Tin

Factiva "An object of the present invention is to provide a process for producing a dialkyl tin compound from a composition of deactivated forms of a dialkyl tin catalyst, and to provide a process for producing the dialkyl tin catalyst from the dialkyl tin compound and using the dialkyl tin catalyst to produce a carbonic acid ester. According to the present invention, a process for producing a dialkyl tin compound is provided that subjects a composition of the deactivated forms of the dialkyl tin catalyst, formed when producing an ester compound, to an alkyl group redistribution reaction and/or dealkylation reaction."

Baerlocher restarts metal and tin stabilizer production

European Plastics News: "Baerlocher Italia has completed the reconstruction of its manufacturing unit in Lodi, Italy, and will retart production of liquid stabilisers for tin and mixed metal.
“We have implemented the latest technologies, thus fulfilling in every respect the highest quality standards for the production of our range of liquid stabilizers“, says Agostino Savoldi, general manager of Baerlocher Italia."

Hubei Benxing Developed New Technology to Make Methyl Tin Mercaptide

Factiva: "Recently China Petroleum and Chemical Industry Association identified the new technology of making coordinated methyl tin mercaptide, which was developed by Hubei Benxing Chemical Co., Ltd.

Traditional methyl tin mercaptide is a mixture of two compounds that jointly guarantee the stability of polyvinyl chloride resin in processing. No chemical link exists between the two compounds, so the mixture has not taken a coordinated effect in the processing of polyvinyl chloride.

The invention of Hubei Benxing helped to set up a chemical bond between the two compounds. Moreover, the researchers developed special application technology for the coordinated methyl tin mercaptide. In 2009 the company sold around 5 000 tons of coordinated methyl tin mercaptide.

The company has six traditional methyl tin mercaptide production lines and four 2-ethylhexyl thioglycolate production units, with the annual capacity of 10 000 t/a and 7 000 t/a, respectively."

Chemtura Corporation - Tin Stabilizers

Chemtura Corporation: "ChemturaVinyl Additives offers a broad line of MARK tin (organotin) stabilizers including butyl tin, octyl tin and methyl tin mercaptides, and butyl tin carboxylate and octyl tin maleate heat stabilizers for use in rigid, flexible and plasitcized PVC. Heat stabilizers meeting FDA food contact regulations are included in the line. Organo tin stabilizers provide protection during calendering, extrusion and injection molding of rigid PVC. Further tin stabilizers provide good initial color, and good long term heat stability."
