666-30-8

2-Chloro-1,3,3,3-tetrafluoropropene is a halogenated hydrocarbon with the chemical formula C3ClF4. It is a colorless, volatile liquid with a pungent odor. 2-chloro-1,3,3,3-tetrafluoropropene is an important intermediate in the production of various fluoropolymers, such as polytetrafluoroethylene (PTFE) and fluoroelastomers. It is synthesized through the chlorination of 1,1,1,3,3-pentafluoropropane or by the addition of chlorine to tetrafluoroethylene. Due to its high reactivity and the presence of both chlorine and fluorine atoms, 2-chloro-1,3,3,3-tetrafluoropropene is a valuable building block for the synthesis of various fluorinated compounds with unique properties, such as heat resistance, chemical stability, and low surface energy. However, it is also considered a greenhouse gas due to its high global warming potential, and its use and release into the environment are subject to regulations.

666-30-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 666-30-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,6 and 6 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 666-30:
(5*6)+(4*6)+(3*6)+(2*3)+(1*0)=78
78 % 10 = 8
So 666-30-8 is a valid CAS Registry Number.

METHOD FOR PRODUCING 2-CHLORO-1,3,3,3-TETRAFLUOROPROPENE

-

Paragraph 0053-0054, (2017/03/24)

PROBLEM TO BE SOLVED: To provide a production method that suppresses the production of by-product and selectively produces 2-chloro-1,3,3,3-tetrafluoropropene(1224). SOLUTION: The method for producing 2-chloro-1,3,3,3-tetrafluoropropene(1224) comprises bringing an organic base into contact with 2,3-dichloro-1,1,1,3-tetrafluoropropane(234da). The organic base is preferably an organic base having a pKa of 7 or higher and more preferably, is an organic base having a pKa of 10 or higher. The organic base is preferably recovered and reused.

Method for Producing 2-Chloro-1,3,3,3-Tetrafluoropropene

-

Paragraph 0065, (2016/02/16)

A production method of 2-chloro-1,3,3,3-tetrafluoropropene (1224) according to the present invention includes bringing 2,3-dichloro-1,1,1,3-tetrafluoropropane (234da) into contact with an inorganic base having a pKa of 4.8 or greater in an aqueous medium in the presence of a phase transfer catalyst. Preferably, the inorganic base has a pKa of 10 or greater. Further, the phase transfer catalyst is preferably at least one selected from the group consisting of tetrabutylammonium bromide, methyltri-n-octylammonium chloride, benzyltrimethylammonium chloride and tetraethylammonium chloride. It is possible by this method to selectively produce 1224 from 234da.
