Direct Process for the chloromethylsilane synthesis produces a disilane residue (DPR) consisting of compounds MenSi2Cl6−n (n=1–6) in thousands of tons annually. Technologically, much effort is made to retransfer the disilanes into monosilanes suitable for introduction into the siloxane production chain for increase in economic value. Here, we report on a single step reaction to directly form cyclic, linear
完善的用于氯甲基硅烷合成的Müller-Rochow直接工艺产生的乙硅烷残留物(DPR)由每年数千吨的化合物Me n Si 2 Cl 6− n(n = 1–6)组成。从技术上讲,已做了很多努力将乙硅烷重新转移到适合引入硅氧烷生产链中的甲硅烷中,以提高经济价值。在这里,我们报告了一步法反应,即在Et 2中用5 m HCl处理DPR后直接形成环状,线性和笼状硅氧烷 将O溶液在约120°C下放置60小时。对于Si-Si键裂解的简化和瞄准上产物选择性甲基化在硅骨架的品位提高到Ñ ≥4。而且,HCl / Et 2 O试剂也适合在可比较的条件下由相应的甲硅烷生产硅氧烷。
