Cis-2-chloroheptafluoro-2-butene is a halogenated hydrocarbon with the chemical formula C4ClF7. It is a colorless liquid at room temperature and is characterized by its unique molecular structure, where a chlorine atom is attached to a carbon atom in a double bond with another carbon atom, while the remaining carbon atoms are bonded to seven fluorine atoms. cis-2-chloroheptafluoro-2-butene is known for its high chemical stability and low reactivity, which makes it useful in various industrial applications, such as in the production of refrigerants and as an intermediate in the synthesis of other fluorinated compounds. Due to its potential environmental impact, particularly its contribution to ozone depletion, the use of such compounds is regulated under international agreements like the Montreal Protocol.

5954-49-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5954-49-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,5 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5954-49:
(6*5)+(5*9)+(4*5)+(3*4)+(2*4)+(1*9)=124
124 % 10 = 4
So 5954-49-4 is a valid CAS Registry Number.

Preparation method of Z-1,1,1,4,4,4-hexafluoro-2-butene

-

Paragraph 0062; 0063; 0064; 0065; 0066; 0067; 0068-0104, (2017/06/02)

The invention relates to a preparation method of Z-1,1,1,4,4,4-hexafluoro-2-butene, belonging to the field of chemical synthesis. The method comprises the following steps of taking hexachlorobutadiene (HCBD) as a raw material, performing gas-phase catalytic chlorination-fluoridation separation to obtain 2,3-dichlorohexafluoro-2-butene, performing liquid-phase dechlorination to obtain hexafluoro-2-butyne, and preparing the Z-1,1,1,4,4,4-hexafluoro-2-butene (Z-HFO-1336mzz) by means of performing gas-phase catalytic hydrogenation, wherein three reactions are included totally. The Z-1,1,1,4,4,4-hexafluoro-2-butene with high selectivity is obtained by means of performing catalytic hydrogenation by adopting the hexafluoro-2-butyne, and meanwhile the product is easily separated from side products and the raw material. The method disclosed by the invention has the advantages that the original raw material is easily obtained, the activity of a catalyst is high, the service life of the catalyst is long, the raw material can be recycled, and the standard of zero emissions is reached.
