| 应用领域 | Uses: Used as a foam blowing agent and refrigerant、[eChemPortal: SIDSUNEP]、HCFCs: Used as refrigerants、blowing agents、cleaning agents、and fire extinguishing agents (CFC alternatives)、[HSDB]、Used in some sterilant mixtures and as a component in some replacements for CFCs as a refrigerant or for halon as a fire suppressant. Replaces CFC-114 in some heat pumps and special air conditioning equipment.、Minimally used as a refrigerant、its primary use as a refrigerant is in blends、mainly R-401A、in industrial process and transport refrigeration equipment. As a stand-alone refrigerant、it has found some niche applications that reach high condensing temperatures as well as an alternative for CFC-114 in some naval chillers.、HCFC-124 is classified as a partially halogenated chorofluorocarbon and was developed as a substitute for fully halogenated chlorofluorocarbons. HCFC-124's main use is in commercial applications as a blowing agent for polystyrene and polyolefin foams in addition to being a component in refrigerant blends. HCFC-124 is used either in closed systems (for refrigeration uses) or in well-ventilated areas with exhaust systems (in the case of appliance manufacturing)、HCFC-124 is a potential substitute for CFC-11 and CFC-12 use as blowing agent in polyurethane foams.、1-Chloro-1、2、2-tetrafluoroethane、HCFC-124 is a potential substitute for CFCs in aerosols、foams、and refrigerants.、1-Chloro- 1、Industry Uses: Intermediate、Refrigerants、Consumer Uses: Refrigerants、Methods of Manufacturing: Common methods of production of HCFC-124 are hydrofluorination of tetrachloroethylene or hydrodechlorination of 1、1-dichloro-1、2-tetrafluoroethane (CFC-114a). The grade of HCFC-124 purity obtained from either process is greater than 99%.、The most important commercial method for manufacturing CFCs and HCFCs is the successive replacement of chlorine by fluorine using hydrogen fluoride. The traditional、liquid-phase process uses antimony pentafluoride or a mixture of antimony trifluoride and chlorine as catalysts. Continuous vapor-phase processes that employ gaseous hydrogen fluoride in the presence of heterogenous chromium、iron、or fluorinated alumina catalysts also are widely used. Carbon tetrachloride、chloroform、and hexachloroethane (or tetrachloroethylene plus chlorine) are commonly used starting materials for one- and two-carbon chlorofluorocarbons. The extent of chlorine exchange can be controlled by varying the hydrogen fluoride concentration、the contact time、or the reaction temperature.、CFCs and HCFCs、Impurities: The purity of the substance is about 99.7%. Impurities include a variety of saturates and unsaturates.、Chlorofluoroalkanes (and also the alternative HCFCs and HFCs) produced on an industrial scale are subject to stringent standards. Impurities must not exceed the following limits (vol %): acids、moisture、<0.001、higher-boiling fractions、<0.05、and other gases、2.、Chlorofluoroalkanes、Formulations、Preparations: Meforex 124、Forane 12、Arcton 124、Asahiklin AK 124、Suva 124、FE241 (fire extinguisher).、Consumption Patterns: Refrigeration、air conditioning、43%、foam blowing agents、20%、polymer precursors、13%、solvent cleaning、12%、aerosol propellants、2%、medical equipment sterilization、3%、other、7%、Fluorocarbons、Refrigeration、46%、fluoropolymer precursors、28%、Miscellaneous、including aerosol propellants、food freezing and halon manufacture 3%、U.S. Production: 2023: 25、000、000 - <75、000 lb、2022: 25、2021: 25、2020: 25、2-tetrafluoromethane is not produced in commercial quantities.、A small amount of HCFC-124 is produced on a small scale - several kilotons、yr.、world production、Based on the Montreal Protocol、a virtual phase out in the production of HCFC-124 is scheduled by 2020.、Ethane、2-chloro-1、1、2-tetrafluoro- is listed as a High Production Volume (HPV) chemical (65FR81686). Chemicals listed as HPV were produced in or imported into the U.S. in >1 million pounds in 1990 and、or 1994. The HPV list is based on the 1990 Inventory Update Rule. (IUR) (40 CFR part 710 subpart B、51FR21438).、For more U.S. Production (Complete) data for 2-CHLORO-1、2-TETRAFLUOROETHANE (7 total)、please visit the HSDB record page.、General Manufacturing Information: Electrical Equipment、Appliance、and Component Manufacturing、All Other Basic Inorganic Chemical Manufacturing、All Other Chemical Product and Preparation Manufacturing、2-tetrafluoro-: ACTIVE、SRP: The EPA has organized groups of chemicals into two classes according to their ozone-depletion potential.
