Reaction Steps
A 500-ml, four-necked flask equipped with a stirrer, dry ice/acetone condenser, thermometer, and gas inlet tube was charged with 64.5 grams (0.5 mol) of dimethyldichlorosilane and 150 grams of toluene. Into the solution at 30° C., 52 grams (3.06 mol) of ammonia was blown over 2 hours for effecting reaction. At the end of reaction, the reaction solution was passed through a glass filter to remove ammonium chloride resulting from the reaction. The filtrate was subjected to vacuum distillation, obtaining 15.4 grams of hexamethylcyclotrisilazane (yield 42%).
