    摘要： Trivinyl-tin hydroxide forms copolymers with vinyl chloride, styrene, vinyl silanes, methyl methacrylate and acrylates. It may also be used as a stabilizer in polyvinyl chloride compositions, as may be epoxyethyl tin hydroxide obtained from it by epoxidizing the unsaturated linkage(s).ALSO:The invention comprises trivinyl tin hydroxide which is prepared by reacting trivinyltin chloride or bromide with a basic compound in aqueous solution containing sufficient hydroxyl ions to replace all the halogen atoms by hydroxide. Specified bases include sodium and potassium hydroxides, carbonates and bicarbonates, ammonium hydroxide, aniline, pyridine, morpholine, tetraalkyl - ammonium hydroxides, calcium oxide and hydroxide and barium hydroxide. The trivinyltin chloride and bromide may react with the aqueous solution in the pure state, or it may react in solution in an inert hydrocarbon or organic solvent (e.g. benzene, toluene, pentane, hexane, cyclohexane, an alcohol or ether). An inert atmosphere such as nitrogen may be maintained during the reaction if desired. Epoxyethyl tin hydroxides may be obtained by epoxidizing the unsaturated linkages in trivinyltin hydroxide.

    摘要： Organotin compounds are prepared by reacting an organomagnesium chloride (as defined) with an organotin oxide of formula RR1SnO or (R2Sn)2O wherein R and R1 may be the same or different and represent substituted or unsubstituted hydrocarbon radicals and when substituted contain no functional groups which are reactive under the reaction conditions with magnesium or the organomagnesium chloride. The organomagnesium chloride is defined as any well-known Grignard reagent prepared in alkyl ether solution, or the aromatic, vinylic and heterocyclic magnesium chlorides prepared in solution in tetrahydrofuran or equivalent cyclic polymethylene oxide or in ethylene polyether solution. Among others, the following organomagnesium chlorides are specified: ethyl, tert-butyl, octyl, 2,2-difluoroethyl, octadecyl, benzyl, allyl, b -methallyl, decyl, dodecyl, isopropyl, amyl, phenyl, pentachlorophenyl, o-tolyl, xylyl, vinyl, 4-methyl-1-penten-2-yl, buten-3-yl oleyl, cyclohexenyl, cyclopentyl, p-anisyl, tri-chlorobiphenyl, b -naphthyl, diethylaminophenyl, b -thienyl, 6-quinolyl, 5-chlorothienyl and chloromethylquinolyl magnesium chlorides. A list of suitable organotin oxides is given. The process is usually carried out by suspending or dissolving the organotin oxide in an inert organic solvent and adding the Grignard reagent, but in some cases it is preferred to add the organotin oxide to the Grignard reagent in a solvent. Solvents specified include substituted and unsubstituted tetrahydrofuran, tetrahydropyran, heptane, hexane, pentane, octane, isooctane and xylene, or if desired, a mixed solvent (tetrahydrofuran and a hydrocarbon) may be used. In an example, dibutyltin oxide is dissolved in a commercial hydrocarbon solvent (mainly heptane) and a solution of vinyl magnesium chloride added. After refluxing and standing overnight the mixture is hydrolysed, the organic phase decanted, dried and distilled to yield dibutyl divinyltin. Numerous other examples are given.

    摘要： Divinyl tin oxide, a polymeric material composed of units of structure is made by the hydrolysis of divinyl tin chloride or bromide. It will copolymerize with vinyl chloride, styrene, vinyl silanes, methyl methacrylate or acrylates. It may also be used as a stabilizer in polyvinyl chloride compositions, as may epoxyethyl tin oxide, obtained by epoxidizing the unsaturated linkages. The preparation of the polymeric divinyl tin oxides takes place in a basic aqueous solution containing sufficient hydroxyl ions to replace all the halogen atoms with oxygen. Specified bases are Na and K hydroxides, carbonates and bicarbonates, Ca, Ba, NH4 and tetra-alkyl ammonium hydroxides, CaO, aniline, pyridine and morpholine. The divinyl tin halides may be added to the basic aqueous solution as such, or in the form of an organic solution (e.g. in benzine, toluene, xylene, pentane, hexane, heptane, cyclohexane, or an alcohol or ether). Uses.-P.V.C. stabilizers, as above. Anthelmintics for chicken feeds or medicines.ALSO:The invention comprises divinyltin oxide which is prepared by reacting divinyltin chloride or bromide with a basic compound in aqueous solution containing sufficient hydroxyl ions to replace all the halogen atoms by oxygen. Specified bases include sodium and potassium hydroxides, carbonates and bicarbonates, ammonium hydroxide, aniline, pyridine, morpholine, tetra-alkyl-ammonium hydroxides, calcium oxide and hydroxide and barium hydroxide. The divinyltin chloride or bromide may react with the aqueous solution in the pure state, or it may react in solution in an inert hydrocarbon or organic solvent (e.g. benzene, toluene, pentane, hexane, cyclohexane, an alcohol or ether). An inert atmosphere such as nitrogen may be maintained during the reaction if desired. Epoxy ethyl tin oxide may be obtained by epoxidizing the unsaturated linkages in divinyl tin oxide.
