26702-40-9 Usage
General Description
(3,3,3-Trifluoropropyl)methylcyclic siloxanes are a group of organosilicon compounds that contain a unique combination of cyclic siloxane and fluorinated propyl moieties. These chemicals have a wide range of industrial applications due to their unique properties, including high thermal stability, low surface energy, and water repellency. They can be used as additives in coatings, adhesives, and sealants, as well as in the production of specialized materials such as fluorinated polymers. In addition, (3,3,3-trifluoropropyl)methylcyclic siloxanes are commonly used as surfactants and in the manufacturing of personal care products such as cosmetics and skincare formulations. Their versatility and performance characteristics make them valuable components in a variety of industries.
Check Digit Verification of cas no
The CAS Registry Mumber 26702-40-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,7,0 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 26702-40:
(7*2)+(6*6)+(5*7)+(4*0)+(3*2)+(2*4)+(1*0)=99
99 % 10 = 9
So 26702-40-9 is a valid CAS Registry Number.

Process for producing a cyclotrisiloxane in a cracking reaction
-
, (2008/06/13)
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.
