二氢月桂烯醇型硅烷偶联剂的合成

Synthesis of dihydromyrcenol-type silane coupling agent

摘要:

以三乙氧基硅烷和二氢月桂烯醇为原料，在Pt金属络合物（Pt-PMVS）催化剂存在下，进行硅氢加成反应，制备了一种二氢月桂烯醇型硅烷偶联剂[2,6-二甲基-8-(三乙氧基硅基)-2-辛醇]（以下简称DHMS），并通过GC-MS、1H-NMR等确认了主副产物的组成。实验考察了溶剂、反应时间、反应温度以及Pt含量对生成目标产物及副产物的影响。结果表明，通过抑制副反应，并对产物减压蒸馏，可以得到质量分数超过98%的DHMS，总收率为69.7%。

Abstract:

Using platinum complexes(Pt-PMVS) as a catalyst for hydrosilylation reaction of dihydromyrcenol with triethoxysilane, a new type of silane coupling agent, [2,6-dimethyl-8-(triethoxysilyl)octan-2-ol](DHMS) is prepared,and the target product and by-products was characterized. The effects of reaction conditions such as solvent, reaction time, reaction temperature and Pt content reaction on the target product and by-products generation were investigated. The results show that under optimized reaction condition, the DHMS is obtained with yield up to 69.7%,and the purity is higher than 98% in weight.
