摘要
比较了顺-二氯二氨合铂和氯铂酸对含氢硅油与端烯丙基聚醚的硅氢加成反应的催化作用。试验表明,在无溶剂体系中,顺-二氯二氨合铂能催化含氢硅油与端烯丙基聚醚的硅氢加成反应,且用量为2×10-6~5×10-6,仅为氯铂酸用量的十分之一,在70~130℃下反应4~6 h,产物几近无色、透明。
The catalysis of cis-diamineplatinum (II) dichloride and chloroplatinie acid for the hydrosily- lation of hydrogen silicone oil and allyl-terminated polyether polyols was compared. Results showed that cis- diamineplatinum (II) dichloride could accelerate the hydrosilylation of the hydrogen silicone oil and allyl-ter- minated polyether polyols in solvent-free systems, and the concentration of cis-diamineplatinum (II) dichlo- ride was 2×10^-6-5×10^-6, which was one tenth of its counterpant chloroplatinic. After 4 - 6 hours reaction for 70 - 130℃, the reaction product was almost colorless and transparent.
