摘要：
A cyclotrisiloxane represented by the general formula (1):
wherein R¹, R², R³, R⁴ and R⁵ may be the same or different and are each an alkyl group of 1 to 3 carbon atoms and X is a cyclohexyl group or an alkyl group expressed by the formula:
-C n H 2n+1
where n is an integer of 4 to 15. The cyclotrisiloxane is useful as an intermediate for producing silicone oils and silicone rubbers, and the obtained silicone oils and silicone rubbers are excellent in lubricity.
