Usage

General Description

3-Chloro-1,1,1,2,3-pentafluoropropane, also known as HCFC-225ca, is a chemical compound used primarily as a refrigerant and foam blowing agent. It is a colorless, odorless gas with the chemical formula C3H2ClF5. HCFC-225ca is classified as a hydrochlorofluorocarbon (HCFC), which means it contains both chlorine and fluorine atoms, making it a potent greenhouse gas and ozone-depleting substance. Due to its ozone-depleting potential, its production and use have been phased out under the Montreal Protocol, an international treaty designed to protect the ozone layer. As a result, HCFC-225ca is being replaced by more environmentally friendly alternatives in refrigeration and foam insulation applications.

COMPOSITIONS AND PROCESSES FOR PRODUCING CHLOROFLUOROALKENES

A method of making chlorofluorohydrocarbons including, contacting, a fluorinated hydrocarbon reagent in the vapor phase, with hydrogen chloride (HCl). The reaction is conducted in the presence of an effective amount of a catalyst, at an elevated temperature sufficient to effect hydrochlorination to form a reaction mixture including a chlorofluorohydrocarbon.

PROCESSES FOR PRODUCING AND COMPOSITIONS COMPRISING 2,3,3,3-TETRAFLUOROPROPENE AND/OR 1,2,3,3-TETRAFLUOROPROPENE

A process is disclosed for making CF3CF=CH2 or mixtures thereof with CHF=CFCHF2. The process involves contacting CCI3CF2CF3 and optionally CCI2FCF2CCIF2 with H2 in the presence of a catalyst including a catalytically effective amount of palladium supported on a support of alumina, fluorided aluminaand/or aluminum fluoride, to produce a product mixture including CH2=CFCF3 (and when CCI2FCF2CCIF2 is present, CHF=CFCHF2); recovering CH2=CFCF3 or a mixture thereof with CHF=CFCHF2 from the product mixture; and optionally, separating at least a portion of any CHF=CFCHF2 in the product mixture from the CH2=CFCF3 in the product mixture. The mole ratio of H2 to the total of CCI3CF2CF3 and CCI2FCF2CCIF2 fed to the reaction zone is between about 1 :1 and about 5:1. The present invention also provides another process for making CH2=CFCF3 Or mixtures thereof with CHF=CFCHF2 This process involves (a) reacting CCI3CF2CF3 and optionally CCI2FCF2CCIF2 with H2 in the presence of a catalytically effective amount of a hydrogenation catalyst to form CH3CF2CF3 (and when CCI2FCF2CCIF2 is present, CH2FCF2CHF2); (b) dehydrofluorinating CH3CF2CF3 and optionally any CH2FCF2CHF2 from (a) to form a product mixture including CH2=CFCF3, and if CH2FCF2CHF2 is present, CHF=CFCHF2; (c) recovering CH2=CFCF3 or a mixture thereof with CHF=CFCHF2 from the product mixture formed in (b); and optionally (d) separating at least a portion of any CHF=CFCHF2 in the product mixture formed in (b) from the CH2=CFCF3 in the product mixture formed in (b). The present invention also provides compositions involving CH2=CFCF3 and/or CHF=CFCHF2, including compositions useful as refrigerants, foam blowing agents, cleaning agents and aerosols and azeotropic compositions involving (a) CF2HCF=CFH and (b) HF.

A process is disclosed for making CH2=CFCF3. The process involves contacting CH2CICF2CF3 with H2 in a reaction zone in the presence of a catalyst including a catalytically effective amount of palladium supported on a support selected from chromium oxide, fluorinated chromium oxide, chromium fluoride, aluminum oxide, aluminum fluoride and/or fluorinated alumina, to produce CH2=CFCF3. The mole ratio of H2 to the CH2CICF2CF3 fed to the reaction zone is between about 1 :1 and about 4:1. Also disclosed is another process for making CH2=CFCF3 that involves (a) reacting CH2CICF2CF3 with H2 in the presence of a catalytically effective amount of hydrogenation catalyst to form CH3CF2CF3; and (b) dehydrofluorinating CH3CF2CF3 from (a) to form CH2=CFCF3;and another process for making CH2=CFCF3 that involves (1 ) dehydrofluorinating CH2CICF2CF3 in the presence of a catalytically effective amount of dehydrofluorination catalyst to form CHCI=CFCF3; and (2) hydrogenating CHCI=CFCF3 from (1 ) in the presence of a hydrogenation catalyst including a catalytically effective amount of palladium supported on a support selected from chromium oxide, fluorinated chromium oxide, chromium fluoride, aluminum oxide, aluminum fluoride and/or fluorinated alumina to form CH2=CFCF3. Also disclosed is a process for making CH2CICF2CF5. This process involves reacting CH2CIF with CF2=CF2 in a reaction zone in the presence of a catalytically effective amount of an aluminum halide composition having a bulk formula of AICIxBryF3-x-y wherein the average value of x is O to 3, the average value of y is O to 3-x, provided that the average values of x and y are not both O. Also disclosed is an azeotropic composition including CF3CF=CHCI and HF.
