摘要: 选用含氢量为1.4%的高含氢硅油(DH)和六甲基二硅氧烷(MM)为原料,强酸型离子交换树脂作催化剂,采用随机质心衍射优化法对1,1,1,3,5,5,5-七甲基三硅氧烷(MDHM)的合成工艺进行优化。此过程仅用了13次试验,优化所得工艺条件为:m(DH)∶m(MM)=1∶13.03,催化剂用量为6.34%,反应温度65.3 ℃,反应时间8.15 h,在该条件下所得产物的平均产率为39.56%。

Abstract: Synthesis of 1,1,1,3,5,5,5-heptamethyltrisiloxane (MDHM) was processed by adopting high hydrogen-content silicone (DH) that containing 1.4% (mass fraction) of hydrogen and hexamethyldisiloxane (MM) as starting materials and strong acidic ion exchange resin as catalyst.The synthesis process was optimized by applying Random-Centroid Optimization Method.Only 13 tests were needed for the optimization and results showed that the optimal conditions were as follows:reaction mass ratio,m(DH)∶m(MM)=1∶13.03;dosage of the catalyst,6.34%;reaction temperature and time,65.3 ℃ and 8.15 h,respectively.Average yield of the product achieves 39.56%.

Key words: 1,1,1,3,5,5,5-heptamethyltrisiloxane, Random-Centroid Optimization Method, strong acidic ion exchange resin
