高沸点甲基氯硅烷的资源化利用

Resource Utilization of Methyl Chlorosilane with High Boiling Point

通过实验证明了二甲精馏过程中产生的高沸点甲基氯硅烷以及催化裂解法产出粗单体中的高沸点甲基氯硅烷经过分离后,采出的沸点低于140℃的甲基氯硅烷。经水解、洗涤后,制备的高沸硅油外观澄清透明、粘度适中、无反酸现象、洗涤过程中无乳化现象,较易实现水油分离。以实验技术指标为依据,推广至生产实践当中,成功实现了高沸点甲基氯硅烷的资源化利用,有效缓解了高沸物处理带来的安全、环保问题。

The experiment proves that the high-boiling methyl chlorosilane produced in the process of dimethyl rectification and the highboiling methyl chlorosilane in the crude monomers produced by the catalytic cracking method,and the methyl chlorosilane with a boiling point lower than 140℃ is separated.After hydrolysis and washing,the prepared high-boiling silicone oil has clear and transparent appearance,moderate viscosity,no reverse acid phenomenon,no emulsification during washing,and it is easier to achieve separation of water and oil.Based on the experimental technical indicators,it was promoted into production practice,and the resource utilization of high-boiling methyl chlorosilane was successfully achieved,effectively alleviating the safety and environmental problems caused by the treatment of high-boiling materials.
