专利号:WO-9212984-A1 优先权日:1991-01-22 标 题:Method for the direct synthesis of organo-tin chlorides, and the use of such chlorides 发明人:MALGUZZI ROMUALDO; SANDRI MAURIZIO; ROSENTHAL MICHAEL; PUERZER ALBERT W 权利人:BAERLOCHER GMBH 摘要:The invention concerns a method of synthesizing directly organo-tin chlorides of the formula RnSnCl4-n, in which n = 1 or 2 and R is a straight-chain, branched-chain or cycloaliphatic alkyl rest with 4 to 18 C-atoms, by reacting tin(II)-chloride with alkyl chlorides. The method is characterized in that the reaction is carried out in the presence of amines of the general formula A: R1aN[(CH2CH2O)m CH2CH2OR2]3-a and/or substituted ammonium chlorides of the formula B: R1bN[(CH2CH2O)mCH2CH2OR2]4-b Cl in which a = 0, 1 or 2; b= 0, 1, 2 or 3; R1 is a straight-chain, branched-chain or cycloaliphatic alkyl group with 2 to 24 C-atoms, or an aryl, alkylaryl or substituted-aryl group, and if a = 2 or b = 2 or 3, the R1 groups may be the same or different; R2=H is a straight-chain or branched-chain alkyl group with 1 to 20 C-atoms, or an aryl, substituted-aryl or alkylaryl group; and m = 1 to 20. Organo-tin chlorides produced in this way are particularly suitable for use as intermediates in the preparation of thermostabilizers for PVC resins.

专利号:US-12129358-B2 优先权日:2020-02-24 标题 :Alkyl-bridged tin-based thermal stabilizers for halogenated resins and synthesis and uses thereof 发明人:ROSS KEVIN JOHN; NORRIS GENE KELLY 权利人:PMC ORGANOMETALLIX INC 摘要:The present invention relates to stabilizer composition for halogen-containing polymer. It has recently been found that tin-based thermal stabilizers with a bridging alkyl group between two tin centers are effective stabilizers while having effectively double the molecular weight of the corresponding non-alkyl bridged stabilizer. It is expected that ongoing experimentation will confirm that the alkyl bridged stabilizers have much lower volatility which leads to greater retention of the stabilizer in the finished article.
