Two butyl tin oxide is an important chemical raw material. Brief description of the process of two butyl tin chloride is added to the hydrolysis reaction kettle, adding n-heptane from high trough, steam heated to 65 DEG C, start dropping alkali solution concentration of 10%, about 3 hours after adding; static layering, the two reactor to upper, lower water separated by adding solid ion-exchange membrane caustic soda and repeatedly apply, repeatedly apply chloride solid sodium in aqueous phase and the aqueous phase centrifugal separation of solid sodium chloride. Then, the alkali solution is added for 50 hours at the temperature of the reaction chamber for 2 hours, and then, after the end of the reaction tank, the utility model is in a static state and is divided into layers, and then is transferred to a distillation kettle, and then the positive heptane (98 DEG C) is distilled, and then the water is washed by centrifugation. The filter cake is dried, crushed, measured and packed into products.
