摘要:
A method of forming chloro-substituted silanes from the reaction of an alkoxy-substituted silane with hydrogen chloride as chlorinating agent is provided. For instance, chloro-substituted silanes, may be formed by reacting the chlorinating agent with an alkoxysilane having the formula (R'O) 4-x SiR x , where R and R' are independently selected alkyl groups comprising one or more carbon atoms and x is 0, 1, 2, or 3. The chloro-substituted silane formed in the reaction along with several by-products has the formula (R'O) 4-x-y SiR x Cl y ; where x is 0, 1, 2, or 3 and y is 1, 2, 3, or 4. One of the by-products of the reaction is an alkyl chloride.
