175401-04-4 Usage
General Description
2,2,4-TRICHLORO-1,1,1-TRIFLUOROBUTANE is a chemical compound that belongs to the class of chlorofluorocarbons (CFCs). It is a colorless, non-flammable gas with a slightly sweet odor, and it is used as a refrigerant, solvent, and a blowing agent for foam insulation. 2,2,4-TRICHLORO-1,1,1-TRIFLUOROBUTANE has a high ozone depletion potential and contributes to the destruction of the ozone layer in the atmosphere. Due to its harmful environmental effects, its production and use have been restricted under the Montreal Protocol, an international treaty aimed at protecting the ozone layer. Additionally, it is a greenhouse gas with a high global warming potential, contributing to climate change. Therefore, efforts are being made to phase out the use of 2,2,4-TRICHLORO-1,1,1-TRIFLUOROBUTANE and find alternative, more environmentally friendly substances for the applications it serves.
Check Digit Verification of cas no
The CAS Registry Mumber 175401-04-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,5,4,0 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 175401-04:
(8*1)+(7*7)+(6*5)+(5*4)+(4*0)+(3*1)+(2*0)+(1*4)=114
114 % 10 = 4
So 175401-04-4 is a valid CAS Registry Number.

Preparation, fluorination and synthetic utility of a CFC-olefin adduct
Van Der Puy, Michael,Demmin, Timothy R.,Bindu Madhavan,Thenappan, Alagappan,Tung, Harry S.
, p. 49 - 54 (2007/10/03)
1,1,1-Trichlorotrifluoroethane was added to ethylene using the catalyst system Fe/triethylphosphite, which eliminated the need for a solvent and avoided the corrosion problems inherent in CuCl-catalyzed reactions. The adduct, CF3CCl2CH2CH2Cl, was fluorinated with HF over a chromium(III) oxide catalyst. A series of alternating dehydrochlorinations and HF additions to internal C=C double bonds was proposed and supported by thermodynamic calculations to explain the formation of CF3CF2CH=CH2 as the principal fluorination product. An intermediate, CF3CCl=CHCH2Cl, formed cleanly by dehydrochlorination of the adduct in the absence of HF, was converted into 4,4,4-trifluorobutanol and other compounds of the type CF3CCl=CHCH2X (X =OAc, OH, Br, I, H).
