Butane, 2,2,3,3-tetrafluoro-, also known as 2,2,3,3-tetrafluorobutane or HFC-1341, is a colorless, odorless, and non-toxic gas with the chemical formula C4H6F4. It is a halogenated hydrocarbon, specifically a fluorocarbon, and is used as a refrigerant, blowing agent, and fire suppressant. Due to its low global warming potential and non-ozone depleting properties, it is considered an environmentally friendly alternative to traditional chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). However, it is still a greenhouse gas and contributes to climate change, so its use is being phased out in favor of more sustainable options.

421-74-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 421-74-9 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 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 421-74:
(5*4)+(4*2)+(3*1)+(2*7)+(1*4)=49
49 % 10 = 9
So 421-74-9 is a valid CAS Registry Number.

THERMAL DECOMPOSITION OF 2,2-DIFLUOROPROPIONYL PEROXIDE IN HYDROCARBON SOLVENTS

Zhuravlev, M. V.,Burmakov, A. I.,Bloshchitsa, F. A.,Sass, V. P.,Sokolov, S. V.

, p. 1597 - 1601 (2007/10/02)

The thermal decomposition of 2,2-difluoropropionyl peroxide in heptane is a monomolecular process with a rate constant of 1.1E13 expsec-1.The main gaseous products from the decomposition of the peroxide in heptane and isooctane are 1,1-difluoroethane, 1,1-difluoroethylene, and 2,2,3,3-tetrafluorobutane.The CH3CF2. radicals generated in this process take part in the abstraction of hydrogen atoms from the solvent, disproportionation, and recombination.The decomposition of the peroxide at low initial concentrations in heptane can be used as a method for the generation of CH3CF2. radicals for kinetic investigations.
