摘　　要：为解决传统以硫酸为催化剂制备二甲基硅油所存在的成本高、工序复杂、对环境污染等问题,在研究制备固体超强催化剂工艺流程的基础上,设计了以八甲基环四硅氧烷和六甲基二硅氧烷为原料合成二甲基硅油的实验方案,并采用单因素分析法确定了合成二甲基硅油新型工艺的最佳参数,获取了原料比与二甲基硅油粘度之间的关系,为后续工业化生产提供指导。In order to solve the problems of high cost,complicated procedures and environmental pollution in the preparation of dimethylsilicone oil using sulfuric acid as the traditional catalyst,an experimental scheme for the synthesis of dimethylsilicone oil using octamethylcyclotetrasiloxane and hexamethyldisiloxane as raw materials was designed on the basis of the process of preparing solid super catalyst.The relationship between the raw material ratio and the viscosity of dimethylsilicone oil was obtained to provide guidance for the subsequent industrial production.
