662-35-1 Usage
Uses
Used in Air Conditioning and Cooling Systems:
1,1,1,2,2,3,3,4-OCTAFLUOROBUTANE is used as a refrigerant for its non-ozone depleting properties, serving as a suitable substitute for chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), which are known to deplete the ozone layer.
Used in the Production of Foam Insulation:
In the manufacturing industry, 1,1,1,2,2,3,3,4-OCTAFLUOROBUTANE is used as a blowing agent, facilitating the creation of foam insulation by expanding materials to achieve desired properties.
Used in Aerosol Products:
1,1,1,2,2,3,3,4-OCTAFLUOROBUTANE is utilized as a propellant in aerosol products, providing the force necessary to dispense the contents from the container.
Used in Environmental Regulations:
Due to its classification as a greenhouse gas with a high global warming potential, 1,1,1,2,2,3,3,4-OCTAFLUOROBUTANE is subject to regulations under the Montreal Protocol, which aims to reduce the impact of substances contributing to ozone depletion and climate change.
Check Digit Verification of cas no
The CAS Registry Mumber 662-35-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,6 and 2 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 662-35:
(5*6)+(4*6)+(3*2)+(2*3)+(1*5)=71
71 % 10 = 1
So 662-35-1 is a valid CAS Registry Number.

THE FLUORINATION OF BUTANE OVER COBALT TRIFLUORIDE
Burdon, James,Ezmirly, Saleh T.,Huckerby, Thomas N.
, p. 283 - 318 (2007/10/02)
The fluorination of butane over cobalt trifluoride has given a complex mixture of partially fluorinated compounds: 51 of these have been identified, comprising over 99percent of the products.Most were polyfluor-butanes but 1-2percent were polyfluoro-2-methylpropanes.The reaction has no synthetic utility.There was some selectivity in the fluorination: secondary C-H was convertart byed into C-F more easily then primary, and the ease of replacement of a particular H was reduced by geminal vicinal fluorines.A computer model of the fluorination was only partially successful, perhaps because the fluorination proceeded in part by simple F for H replacement and in part via alkenes: the model only allowed for the former.
