| titleOfInvention | Process for the preparation of a mixture of n-octyltin chlorides which is entirely free from tri-n-octyltin chloride |
| abstract | 1313485 Preparing di- and mono-n-octyltin chlorides INSTYTUT PRZEMYSLU ORGANICZNEGO 1 June 1971 [6 June 1970] 18326/71 Heading C2J A mixture of di- and mono-n-octyltin chlorides which is entirely free from tri-noctyltin chloride is prepared by directly reacting tin and n-octyl chloride in the presence of, as catalyst, 0À03-0À08 mol of PCl 3 per g-atom of tin and simultaneously distilling off the α-octene formed. The reaction is normally effected at 175-200‹ C. in the presence of a small amount of n-octyl iodide and using excess n-octyl chloride as solvent. In Example 1, the n-octyltin trichloride is distilled off from the reaction product and saponified in aqueous NaOH to give n-octyl tin acid, the remaining di-n-octyltin dichloride being hydrolysed in aqueous alcoholic NaOH to yield di-n-octyltin oxide. |
