335-68-2 Usage
Uses
Used in the Chemical Industry:
1,1,3,5,7,8-HEXACHLOROPERFLUOROOCTANE is used as a surfactant for the production of non-stick coatings, such as those found in cookware, due to its heat and chemical resistance properties.
Used in the Textile Industry:
In the textile industry, 1,1,3,5,7,8-HEXACHLOROPERFLUOROOCTANE is utilized as a surfactant in the creation of waterproofing fabrics, capitalizing on its water-repellent characteristics.
However, due to its persistence in the environment and potential to bioaccumulate, there are growing concerns about the impact of 1,1,3,5,7,8-HEXACHLOROPERFLUOROOCTANE on human health and the environment. Consequently, this chemical compound has faced regulatory restrictions in some countries to mitigate its environmental and health risks.
Check Digit Verification of cas no
The CAS Registry Mumber 335-68-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,3 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 335-68:
(5*3)+(4*3)+(3*5)+(2*6)+(1*8)=62
62 % 10 = 2
So 335-68-2 is a valid CAS Registry Number.

Reaction of 1,2-Dichloroiodotrifluoroethane With Zinc
Eapen, K. C.,Tamborski, C.
, p. 421 - 424 (2007/10/02)
The zinc coupling reaction of 1,2-dichloroiodotrifluoroethane (I) in acetic anhydride-methylene chloride has been reinvestigated in more detail than its original disclosure.The expected coupling product C4F6Cl4 was shown to be an isomeric mixture of three components, CF2ClCFClCFClCF2Cl (II, 80percent), CFCl2CF2CF2CFCl2 (IIa, 15percent) and CF2ClCFClCF2CFCl2 (IIb, 5percent).In addition, other products e.g.CF2-CFCl, C6F9Cl5 and C8F12Cl6 were formed in minor quantities.A probable mode of formation of various byproducts via initial formation of CF2-CFCl and subsequent telomerization is presented.
