673-93-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 673-93-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,7 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 673-93:
(5*6)+(4*7)+(3*3)+(2*9)+(1*3)=88
88 % 10 = 8
So 673-93-8 is a valid CAS Registry Number.

METHOD FOR PRODUCING 1,2-DICHLORO-3,3,3-TRIFLUOROPROPENE

-

Paragraph 0053; 0054, (2015/07/15)

A method for producing 1,2-dichloro-3,3,3-trifluoropropene of the present invention includes reacting 1,2-dichloro-1-halogeno-3,3,3-trifluoropropane with a base in a liquid phase; and extracting generated 1,2-dichloro-3,3,3-trifluoropropene to the outside of a reaction system to recover while the reaction is continued. According to the present invention, 1,2-dichloro-3,3,3-trifluoropropene is obtained at a high yield by a simple method. Thus, 1,2-dichloro-3,3,3-trifluoropropene is produced in an industrial scale.

PROCESS FOR CIS-1-CHLORO-3,3,3-TRIFLUOROPROPENE

Page/Page column 2, (2012/09/05)

Disclosed is a process for making one isomer of CF3CH═CHCl. More particularly, the invention comprises the production of CF3C≡CCl and its selective reduction to cis-1-chloro-3,3,3-trifluoropropene (CF3CH═CHCl).

Reactions of perfluorinated alkenyl-, alkynyl-, alkyltrifluoroborates, and selected hydrocarbon analogues with the halogenating agents Hal2 (Hal = F, Cl, Br), "brF" (BrF3-Br2 1:1), and ICl

experimental part, p. 565 - 579 (2012/05/20)

Reactions of [Bu4N][RBF3] [R = CnF 2n+1CF=CF (cis, trans), CF2=CF, CF2=C(CF 3), trans-C4H9CF=CF, trans-C6H 5CF=CF, C4H9CH=CH (cis, trans), CF 3C≡C, and C4H9C≡C] with chlorine, bromine, BrF3 + Br2 (as equivalent of "BrF"), and ICl in solution (CH2Cl2, CHCl3, CF 3CH2CF2CH3) led to 1, 2-addition of halogen and/or replacement of boron by halogen (halodeboration). The reaction of [Bu4N][CF3C≡CBF3] with less than equimolar amounts of diluted fluorine (5 %) in 1, 1, 1, 3, 3-pentafluorobutane (PFB) showed only [Bu4N][CF3CF2CF 2BF3] as fluorine addition product besides extensive fluorodeboration. Suspensions of the insoluble K[CF2=CFBF 3] salt reacted with Cl2 and Br2 in CH 2Cl2 giving preferentially products of halogen addition across the C=C bond. In reactions with ICl iododeboration with formation of CF2=CFI occurred besides 1, 2-addition with formation of [CF 2I-CFClBF3]-. The halodeboration reaction of[Bu4N][trans-C4H9CF=CFBF3] with Br2, "BrF", and ICl, of K[trans-C6H 5CF=CFBF3] with Br2, and of [Bu 4N][trans-C4F9CF=CFBF3] with ICl proceeded stereospecifically.
