| titleOfInvention | Process for the production of alkyltin halides |
| abstract | A process comprising:n (a) contacting a feed stream comprising a di-alkyltin dihalide distillate with an alkylation agent, thereby forming an alkylated mixture comprising R 4 Sn and optionally R 3 SnX, R 2 SnX 2 , or mixtures thereof, where R is a linear, branched or cyclic C 1 -C 20 alkyl, and X is a halide; (b) contacting the alkylated mixture with SnX 4 , thereby forming an alkyltin halide mixture comprising RSnX 3 , R 2 SnX 2 , and optionally impurities, R 3 SnX or mixtures thereof; (c) separating by distillation the alkyltin halide mixture to form a mono-alkyltin halide-rich distillate stream and a liquid di-alkyltin halide-rich bottoms stream comprising R 2 SnX 2 , RSnX 3 , and optionally impurities, R 3 SnX, or mixtures thereof; (d) separating by distillation the di-alkyltin halide-rich bottoms stream, thereby forming the liquid di-alkyltin dihalide distillate comprising R 2 SnX 2 , and optionally RSnX 3 , R 3 SnX or mixtures thereof, and an impurities-rich bottoms stream; and (e) recycling a part, x recycle , of the liquid di-alkyltin dihalide distillate to step (a), where x recycle ranges from greater than 0.0% to 100.0% of the distillate. |
