An improved process for increasing the yield and purity of fluoroalkyl cyclotrisiloxanes in a cracking reaction of diorganopolysiloxanes by using, in addition to the cracking catalyst, an effective amount of a higher aliphatic alcohol having from 14 to 30 carbon atoms. By the use of such a higher aliphatic alcohol, there is consistently obtained yields of high purity fluoroalkyl cyclotrisiloxanes from cracking reactions of silicone hydrolyzates in excess of 80% by weight.
