Abstract

Silicohydrogen addition method was utilized to prepare long-chain alkyl silicone oils using high hydrogen-containing silicone oil, α-methylstyrene, and 1-tetradecene as raw materials and chloroplatinic acid as catalyst. FTIR and ¹H-NMR were used to characterize the structure of the products, and the effects of reaction temperature, reaction time, catalyst dosage, and n(Si-H): n(C=C) on the Si-H conversion were investigated experimentally to determine the optimal reaction process. The experimental results showed that the optimized process conditions were n(Si-H): n(C=C) =1:1.1, reaction time of 6 h, reaction temperature of 150 °C, catalyst dosage of 2 ppm, and the Si-H conversion of the product was 96.3%.
