Abstract
Tributyltin chloride is important chemical products.Brief description of the process：By tetrabutyltin（200L barreleds）With vacuum sucting reaction kettle, the logical chilled brine of chuck cools to less than 15 DEG C, is slowly added to butter of tin（Keep the temperature between 0-5 DEG C）, after the completion of reaction, extraction kettle is gone to, normal heptane and water are added from normal heptane head tank and water head tank respectively, to stir, stand, be layered, upper strata is the n-heptane solution of tributyltin chloride, and lower floor is the aqueous solution of monobutyl stannic chloride, lower floor's barrelling（Production monobutyl tin oxide）, normal heptane is reclaimed on upper strata in extraction kettle（Distillation normal heptane temperature is 70-100 DEG C）, after solvent recovery terminates, drying kettle is transferred to, in 100-120 DEG C of drying, after drying terminates, less than 50 DEG C are cooled to, packed after being filtered through filter.Reuse is collected after all solvents are condensed.
Description
Brief description of the process is by tetrabutyltin（200L barreleds）With vacuum sucting reaction kettle, the logical chilled brine of chuck cools to less than 15 DEG C, is slowly added to butter of tin（Keep the temperature between 0-5 DEG C）, after the completion of reaction, extraction kettle is gone to, normal heptane and water are added from normal heptane head tank and water head tank respectively, to stir, stand, be layered, upper strata is the n-heptane solution of tributyltin chloride, and lower floor is the aqueous solution of monobutyl stannic chloride, lower floor's barrelling（Production monobutyl tin oxide）, normal heptane is reclaimed on upper strata in extraction kettle（Distillation normal heptane temperature is 70-100 DEG C）, after solvent recovery terminates, drying kettle is transferred to,
100-120 DEG C of dryings, after drying terminates, are cooled to less than 50 DEG C, are packed after being filtered through filter.Reuse is collected after all solvents are condensed.
Reacting the equation being related to is（Reaction conversion ratio 99.9% in terms of butter of tin, yield is 99.8%）：
Side reaction：
