Description
技术领域technical field
本实用新型涉及一种甲基氯硅烷混合单体脱高沸装置，涉及有机硅行业甲基氯硅烷混合单体的精制。The utility model relates to a high boiling device for methyl chlorosilane mixed monomers, and relates to the refining of methyl chlorosilane mixed monomers in the organosilicon industry.
背景技术Background technique
目前，混合甲基氯硅烷单体脱高沸装置，一般采用板式塔操作，塔顶温度控制68～70℃，顶部压力在5～30KPa，因甲基氯硅烷单体中高沸物沸点和其它甲基氯硅烷单体沸点接近，在甲基氯硅烷单体中(高沸＞70.2℃，二甲基二氯硅烷沸点70.2℃)，但是由于板式塔效率底下，因而不利于高沸物分离。采用波纹丝网填料塔效率相对高，但由于甲基氯硅烷混合单体中含有硅粉等杂质，容易堵塞精馏塔内填料，运行一段时间后，塔内填料堵塞传热、传质效率下降，如何精制脱除甲基氯硅烷混合单体中高沸物，一直是个难题。At present, the high boiling device for mixed methyl chlorosilane monomer is generally operated by plate tower, the temperature at the top of the tower is controlled at 68-70°C, and the top pressure is 5-30KPa. The boiling point of methylchlorosilane monomer is close to that of methylchlorosilane monomer (high boiling point > 70.2°C, dimethyldichlorosilane boiling point 70.2°C), but due to the low efficiency of the plate tower, it is not conducive to the separation of high boilers. The efficiency of the corrugated screen packing tower is relatively high, but because the mixed monomer of methyl chlorosilane contains silicon powder and other impurities, it is easy to block the packing in the rectification tower. After a period of operation, the packing in the tower will block the heat transfer and reduce the mass transfer efficiency. , How to refine and remove the high boilers in the mixed monomer of methyl chlorosilane has always been a difficult problem.
