摘要：
A process of producing a methylphenyltrisiloxane having the following general formula:
wherein R¹ and R² may be the same or different and are each a methyl or phenyl group, the process comprising the step of reacting:
(A) methyldiphenylsilanol, with
(B) a silazane compound having a diorganosilazane unit having the following formula:
wherein R¹ and R² are as defined above. According to the process, colorless and odorless methylphenyltrisiloxanes can be obtained easily, safely and economically, without any special deodorizing or decoloring step.
