摘要: THE INVENTION RELATES TO THE PROCESS FOR THE DIRECT MANUFACTURE OF DIALKYTIN OXIDE THROUGH SUCH REACTION STEPS THAT ALKYL IODINE IS REACTED DIRECTLY WITH METALLIC TIN TO DIALKYTIN IODINE WHICH IS THEN HYDROLYZED TO THE DESIRED PRODUCT. THE MAIN OBJECT OF THE INVENTION IS TO PROVIDE A PROCESS FOR THE MANUFACTURE OF DIALKYLTIN OXIDE WITH LEAST POSSIBLE LOSS OF IODINE AND AT A MAXIUM POSSIBLE PURITY OF THE FINAL PRODUCT. FOR THIS PURPOSE, AN AQUEOUS ALKALINE SOLUTION APPEARED FROM A CERTAIN PROCESSING STAGE AND CONTAINING UNRECOVERED ALKALI METAL IODINE AFTER EXCUTION OF THE RECOVERY STEP THEREOF IS RETURNED TO SAID FIRST STEP FOR RECICULATION.

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.
