429-67-4 Usage
General Description
1,3,5,7-TETRAKIS(3,3,3-TRIFLUOROPROPYL)1,3,5,7-TETRAMETHYLCYCLOSILOXANES, also known as Tetrakis(trifluoropropyl)methylcyclotetrasiloxane, is a chemical compound that belongs to the class of organosilicon compounds. It is composed of a cyclic structure with four silicone atoms and four methyl groups, each attached to a trifluoropropyl group. 1,3,5,7-TETRAKIS(3,3,3-TRIFLUOROPROPYL)1,3,5,7-TETRAMETHYLCYCLOSILOXANES is used as a surface treatment agent to provide water and oil repellency to various materials such as textiles, paper, and leather. It is also used as a lubricant and release agent in various industrial applications. Additionally, it is employed in the production of silicone rubber and silicone resins due to its unique chemical and physical properties.
Check Digit Verification of cas no
The CAS Registry Mumber 429-67-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 429-67:
(5*4)+(4*2)+(3*9)+(2*6)+(1*7)=74
74 % 10 = 4
So 429-67-4 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.
