Hydrochloric Acid → Methyldiisopropylchlorosilane

Temperature

100 °C

A thermometer, hydrogen chloride gas inlet tube, and reflux condenser were fitted to a stirrer-equipped 200 mL four-neck flask, and 100 g methyldiisopropylsilane was then introduced into the flask. This was followed by the addition of 0.01 g platinum/divinyltetramethyldisiloxane complex and heating to 100° C. Hydrogen chloride gas was then introduced into the mixture. The introduction of hydrogen chloride gas was suspended after 4 hours. Distillation at ambient pressure yielded 122 g methyldiisopropylchlorosilane (purity≥99%, bp=146° C.). The methyldiisopropylchlorosilane yield was 97%.
