A method for preparing a partially fluorinated ester comprising acyl and alkoxy groups wherein the acyl group comprises a branched or linear fluorine containing C-Cgroup with one of the structures: (Formulae (I), (II)) wherein X and Y are independently selected from: —H, —CH, —F, —Cl, —CHF, —CF—OCF, —OCHCF, OCHCFCHFand —CHCF(wherein both X and Y cannot be H) comprising reacting an unsaturated halocarbon: (Formula (III)) wherein A and B are independently selected from the group comprising —H, —CH, —F, —Cl, —CHF, —CF, —OCF, —OCHCF, OCHCFCHFand —CHCF(wherein both A and B cannot be H) with carbon monoxide and an alcohol, in the presence of a catalyst methods.

Methods for preparing partially fluorinated esters

The invention relates to a process for preparing 2,3,3,3-tetrafluoropropene (CFCF&#x2550;CH), performed using the steps of dehydrohalogenating 1,1,1,2,2-pentafluoropropane (CHCFCF, HFC-245ca) 1,1,1,2-tetrafluoro-2-chloropropane, 1,1,1,2,3-pentafluoropropane (CHFCHFCF, HFC-245eb) and/or 1,1,1,2-tetrafluoro-3-chloropropane in the presence of a base, and converting a trifluorodichloropropane or a difluorotrichloropropane or a fluorotetrachloropropane to CHCFCF, 1,1,1,2-tetrafluoro-2-chloropropane, CHFCHFCF, and/or 1,1,1,2-tetrafluoro-3-chloropropane.

Process for preparing R-1234yf by base mediated dehydrohalogenation

A process for isomerizing a (hydrohalo)fluoroalkene, the process comprising contacting the (hydrohalo)fluoroalkene with a catalyst a catalyst which is a chromia-containing catalyst supported on AlFor fluorinated alumina.

Process for isomerizing A (hydro)fluoroalkene

A process for isomerising a (hydrohalo)fiuoroalkene, the process comprising contacting the (hydrohalo)fluoroalkene with a catalyst comprising an unsupported Lewis acid, a chromia-containing catalyst containing at least one additional metal, an alumina, a supported liquid catalyst, and mixtures thereof.

Process for isomerizing a (hydro)fluoropropene

The invention relates to a process for preparing a compound of formula CFCF&#x2550;CHX, CHXCX&#x2550;CXor a linear or branched C(hydro)fluoroalkene, wherein each X is, independently, H or F provided that in CHXCX&#x2550;CXat least one X is F, which process comprises dehydrohalogenating a compound of formula CFCFYCHX, CFCFHCYHX, CHXCXYCXH, CHXCXHCXY, or a linear or branched Chydro(halo)fluoroalkane, wherein each X is, independently, H or F provided that in CHXCXYCXH and CHXCXHCXY at least one X is F, wherein Y is F, Cl, Br, or I, in the presence of a base.

Process for the preparation of C3-7 fluoroalkenes by base-mediated dehydrohalogenated C3-7 fluoroalkenes

A method of catalytically converting 2,2, dichlorohexafluoropropane (HFC-216aa) into 2 chloro 1,1,1,2,3,3,3 heptafluoropropane (HFC-217ba) including the step of exposing the 2,2 dichlorohexafluoropropane to a chromium-containing catalyst comprising a metal oxide, a halogenated metal oxide or a metal oxyhalide, which chromium-containing catalyst comprises 0.01% to 5.0% by weight zinc or a compound of zinc.

Method for the preparation of 2 chloro 1,1,1,2,3,3,3 heptafluoropropane

A process for removing a (hydro)haloalkene impurity from a product stream containing that impurity and a desired compound is described. The process comprises contacting the product stream with a solid adsorbent comprising pores having openings which have a size across their largest dimension in the range of from about 7 &#x212b; to about 10 &#x212b;. The process is particularly suited to the removal of (hydro)halopropene impurities from saturated hydrofluorocarbons such as a tetrafluoroethane, a pentafluoropropane, a hexafluoropropane or a heptafluoropropane.
