ABSTRACT:
A method for preparing cyclotetrasiloxane, aliphatic chlorides and/or acyl chlorides from a cyclotrisiloxane, a chlorosilane and an acyloxy compound is disclosed. The chlorosilane and the acyloxy compound may be present as substantially equimolar amounts of separate compounds or they may be present in the same molecule in equimolar amounts. The reactants are merely heated sufficiently, with or without a soluble halide salt catalyst, to form the products. Advantageously this method can provide cyclotetrasiloxanes having water-sensitive radicals such as silicon-bonded chlorine atoms and/or silicon-bonded acyl chloride radicals. This method also provides a method for preparing cyclotetrasiloxanes having either one type of siloxane unit (non-mixed cyclotetrasiloxanes) or more than one type of siloxane unit (mixed cyclotetrasiloxanes).
