Abstract
Dibutyl tin dilaurate is the important raw and processed materials in chemical industry.The dibutyl tin dilaurate technological process of production is：Add laurate, dibutyltin chloride and solvent n-heptane in a kettle. using vacuum system, the sodium hydroxide solution for preparing is pumped into head tank, dropwise addition enters reactor（Chuck leads to chilled water, below 50 DEG C of kettle temperature）After reaction knot Lianshui Hong Ding Chemical Co., Ltd.s produce 10000 tons of beams of organotin series of products project environment Impact Report book 35 per year, leave heart kettle, separation water phase, water is added to solid ionomer membrane caustic soda, applies mechanically repeatedly, and time produces solid sodium chloride in being used in water phase, water is mutually centrifuged, the solid of sodium chloride is isolated.Lower floor's oil phase is distilled into distillation still, and solvent distillation is carried out at 100 DEG C or so（Normal heptane）Reuse（The condensation efficiency of normal heptane is 99%）, then be transferred to drying kettle and be dried（100-120℃）, dibutyl tin dilaurate is obtained after being filtered through filter.
Description
Brief description of the process adds laurate, dibutyltin chloride and solvent n-heptane using vacuum system in a kettle., and the sodium hydroxide solution for preparing is pumped into head tank, and dropwise addition enters reactor（Chuck leads to chilled water, below 50 DEG C of kettle temperature）, reaction knot
Lianshui Hong Ding Chemical Co., Ltd.s produce per year
10000 tons of organotin series of products project environment Impact Report books
After 35 beams, heart kettle is left, separation water phase, water is added to solid ionomer membrane caustic soda, applies mechanically repeatedly, time produces solid sodium chloride in being used in water phase, and water is mutually centrifuged, and isolates the solid of sodium chloride.Lower floor's oil phase is distilled into distillation still, and solvent distillation is carried out at 100 DEG C or so（Normal heptane）Reuse（The condensation efficiency of normal heptane is
99%）, then be transferred to drying kettle and be dried（ 100—120℃）, dibutyl tin dilaurate is obtained after being filtered through filter.
