1,1,1-Trichloro-4,4,4-trifluoro-butane, also known as CFC-114, is a chlorofluorocarbon (CFC) compound with the chemical formula C4Cl3F3. It is a colorless, volatile liquid at room temperature and is used primarily as a refrigerant, blowing agent, and cleaning solvent. CFC-114 is known for its high chemical stability, low toxicity, and excellent dielectric properties. However, it is also an ozone-depleting substance, contributing to the depletion of the ozone layer when released into the atmosphere. Due to its environmental impact, the production and use of CFC-114 have been phased out under the Montreal Protocol to protect the ozone layer.

407-57-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 407-57-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,0 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 407-57:
(5*4)+(4*0)+(3*7)+(2*5)+(1*7)=58
58 % 10 = 8
So 407-57-8 is a valid CAS Registry Number.

RADICAL TELOMERIZATION OF 3,3,3-TRIFLUORO-1-PROPENE WITH CARBON TETRACHLORIDE

Vasil'eva, T. T.,Fokina, I. A.,Vitt, S. V.,Dostovalova, V. I.

, p. 1638 - 1641 (2007/10/02)

Telomerization of 3,3,3-trifluoropropene with CCl4 was carried out in the presence of Fe(CO)5 in combination with dimethylformamide (DMF) or hexamethylphosphoric triamide (HMPA) with formation of the telomers CCl3(CH2CHCF3)nCl, n = 1-3, as the main products.Chromatography-mass spetrometry showed the presence of CCl3CH2CH(CCl3)CF3, a product of recombination of the adduct radical and CCl3, in the reaction mixture, which confirms the radical nature of the process.The structure of all the products was confirmed by 13C NMR and (or) mass spectrometry.
