haohan岛津DC-550填充柱测定六氯乙硅烷3m*3mm

六氯乙硅烷是一种无机化合物，化学式为Si2Cl6，可以看成一种硅的氯化物。它是一种无色液体，在潮湿空气中发烟。它在用作化学试剂和合成硅单质的挥发性前体方面具有特殊应用。

六氯乙硅烷分子采用乙烷结构，Si-Si单键键长为233pm。六氯乙硅烷是在硅化物氯化过程中产生的，例如二硅化钙。理想的反应方程式如下：
CaSi2 + 4 Cl2 → Si2Cl6 + CaCl2
六氯乙硅烷在空气或氮气中在高达400°C的温度下至少可以稳定数小时，但即使在室温下，在路易斯碱存在下会分解成十二氯代新戊硅烷和四氯化硅，这种转化可用于制造用于包括光伏电池在内的半导体器件的硅基组件。反应方程式为：
4Si2Cl6 → 3SiCl4 + Si5Cl12
该化合物也是脱氧反应的有用试剂，例如还原氧化膦为膦。

It is a colorless liquid that emits smoke in humid air. It has special applications as a volatile precursor for chemical reagents and the synthesis of silicon monomers.



Hexachloroethane molecule adopts an ethane structure, with a Si Si single bond length of 233pm. Hexachloroethane is produced during the chlorination process of silicides, such as calcium disilicate. The ideal reaction equation is as follows:

CaSi2+4 Cl2 → Si2Cl6+CaCl2

Hexachloroethylsilane can stabilize for at least a few hours in air or nitrogen at temperatures up to 400 ° C, but even at room temperature, in the presence of Lewis base, it decomposes into dodecachloroneopentyl silane and silicon tetrachloride. This conversion can be used to manufacture silicon based components for semiconductor devices, including photovoltaic cells. The reaction equation is:

4Si2Cl6 → 3SiCl4+Si5Cl12

This compound is also a useful reagent for deoxidation reactions, such as reducing phosphine oxide to phosphine.
