374-12-9

1,1,2,2-Tetrafluorocyclobutane is a cyclic hydrocarbon compound with the molecular formula C4F8. It is a colorless, volatile liquid with a low boiling point of -5.5°C. 1,1,2,2-tetrafluorocyclobutane is composed of a four-carbon ring structure, where each carbon atom is bonded to two fluorine atoms. Due to its highly fluorinated nature, 1,1,2,2-tetrafluorocyclobutane exhibits unique chemical and physical properties, such as high thermal stability, low reactivity, and excellent dielectric properties. These characteristics make it a valuable compound for various industrial applications, including refrigerants, foam-blowing agents, and as a precursor in the synthesis of other fluorinated compounds. However, it is important to note that 1,1,2,2-tetrafluorocyclobutane is a potent greenhouse gas with a high global warming potential, and its use is regulated under international agreements to mitigate its impact on climate change.

374-12-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 374-12-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,7 and 4 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 374-12:
(5*3)+(4*7)+(3*4)+(2*1)+(1*2)=59
59 % 10 = 9
So 374-12-9 is a valid CAS Registry Number.

Catalytic synthesis of polyfluoroolefins

Stepanov,Delyagina,Cherstkov

experimental part, p. 1290 - 1295 (2011/01/04)

A catalytic synthesis of polyfluoroolefins was developed proceeding from polyfluorochlorocarbons with the use of industrially produced nickel-chromium catalyst. Three ways of the catalytic synthesis of fluoroolefins were implemented: the cleavage of vicinal chlorine atoms from polyfluorochlorocarbons, the replacement of vinyl chlorine atoms by hydrogen in fluorochloroolrfins, and the reductive dimerization of polyfluorochlorocarbons containing a trichloromethyl group. The condition of a prolonged operation of the nickel-chromium catalyst was found consisting in the application of quartz for absorption of the hydrogen fluoride formed as a side product.

CYCLOPROPANE CHEMISTRY. PART 5 . HEXAFLUOROCYCLOPROPANE AS A SOURCE OF DIFLUOROCARBENE

Birchall, J. Michael,Fields, Roy,Haszeldine, Robert N.,McLean, Reginald J.

, p. 487 - 496 (2007/10/02)

Thermolysis of hexafluorocyclopropane in the presence of ethylene, propene, vinyl chloride, and vinyl bromide gives good yields of the corresponding 1,1-difluorocyclopropanes, formed by addition of difluorocarbene to the olefin.The tetrafluoroethylene formed dimerises to octafluorocyclobutane, co-dimerises with the olefin, or survives, depending on the reaction conditions.With allene, hexafluorocyclopropane gives 1-(difluoromethylene)cyclopropane, 2,2,3,3-tetrafluorospiropentane, and products derived from tetrafluoroethylene and allene.
