| 中文摘要: |
| 研究了四甲基二乙烯基二硅氧烷(MviMvi)用量、反应温度、反应时间、其他因素对制备卡斯特铂[Karstedt铂]催化剂的影响，对其结构进行了探析。结果表明，n(MviMvi)/n(氯铂酸)比值为14:1，70 ℃下回流反应1.5 h为适宜反应条件，制备出的卡斯特铂催化剂的室温稳定性达6个月。制备过程的优化，优势结构的获得以及低挥发物质的及时去除都有利于卡斯特铂的稳定性。 |
| 英文摘要: |
| The effects of the amount of 1,1,3,3-tetramethyl-1,3-divinyldisiloxane(MviMvi), reaction temperature and time, and other factors on the stability of Karstedt’s catalyst were studied, and its structure was discussed. The results showed that n(MviMvi)/n(H2PtCl6) ratio of 14:1 was suitable for reflux reaction at 70 ℃ for 1.5 h, and the stability of Karstedt’s catalyst prepared under these conditions was up to 6 months at room temperature. The optimization of the preparation process, the acquisition of dominant structure 2 and the timely removal of low volatile matter will increase the stability of the platinum (0) complexes. |
