登记用途：Uses: Used as a replacement for chlorofluorocarbons、[HSDB] Used as a refrigerant、fire extinguishing agent、plastic foam blowing agent、and solvent in special applications、[eChemPortal: SIDSUNEP]、According to the AFEAS database、more than 99% of HFC-125 produced worldwide by the reporting companies is used as a blend component for commercial refrigeration and air conditioning systems. The use as a fire-extinguishing agent in total flooding systems is another application of HFC-125. Minor applications include the use of HFC-125 in plastic foam blowing and as a solvent in special applications.、Refrigerant.、non-polymer PFAS -> Electronic Industry -> Electrical equipment、appliance、and component manufacturing、non-polymer PFAS -> Electronic Industry -> Heat transfer fluids (cooling of electrical equipment)、non-polymer PFAS -> Air conditioning -> Air conditioning、non-polymer PFAS -> Food Production Industry -> Manufacture of food products and beverages、non-polymer PFAS -> Chemical Industry -> Production of other chemicals、non-polymer PFAS -> Refrigerant systems -> Refrigerants、non-polymer PFAS -> Flame Retardants -> Flame retardants and extinguishing agents、non-polymer PFAS -> Machinery and equipment -> (Electrical) machinery and equipment、non-polymer PFAS -> Cleaning compositions -> Cleaning compositions in general、non-polymer PFAS -> Building and Construction -> General use、• Refrigerant - Heat transfer fluid [Ref: https:、www.epa.gov、chemical-data-reporting、2016-chemical-data-reporting-results]、• Foaming agent for protein fire fighting foams [Ref: CAS 2019 (CN101371944)]、• Construction [Ref: http:、www.spin2000.net、spinmyphp、• Cleaning、washing agents [Ref: http:、• Heat transfer agent [Ref: http:、• Air Conditioner、Refrigeration in Industrial gas manufacturing [Ref: https:、• Cooling agent [Ref: http:、• Functional fluids (closed systems) in electrical equipment、and component manufacturing [Ref: https:、• Refrigerant [Ref: https:、www.ashrae.org、technical-resources、standards-and-guidelines、ashrae-refrigerant-designations]、• Manufacture of food products and beverages [Ref: http:、• Machinery and equipment [Ref: http:、• Manufacture of chemicals and chemical products [Ref: http:、• Flame ratardant and fire extinguishing agent [Ref: http:、• Functional fluids (closed systems) in machinery manufacturing [Ref: https:、Industry Uses: Not Known or Reasonably Ascertainable、Refrigerants、Propellants、non-motive (blowing agents)、Energy Releasers (explosives、motive propellant)、Consumer Uses: Propellants、Not Known or Reasonably Ascertainable、Methods of Manufacturing: Higher temperatures and higher hydrogen fluoride-to-substrate ratios are necessary to achieve complete replacement of all chlorine atoms in the starting chloro compounds by fluorine. Both liquid-phase halogen exchange in the presence of catalysts、such as antimony(V) or tin(IV) chlorofluorides and vapor phase reactions using solid-phase catalysts based on chromium are employed. Preferred starting materials are chloroform for HFC 23、dichloromethane for HFC 32、and 1、1、1-trichloroethane for HFC 143a. The conversion of tetrachloroethylene to HFC 125 and trichloroethylene to HFC 134a involves initial HF-addition across the double bond followed by a series of chlorine-fluorine exchange reactions.、Fluorination of 2、2-dichloro-1、1-trifluoroethane (HCFC-123) is employed to manufacture 2-chloro-1、2-tetrafluoroethane (HCFC-124)、which in turn is fluorinated to 1、2、2-pentafluoroethane (HFC-125).、Consumption Patterns: Refrigerants、39%、foam blowing agents、17%、solvents、14%、fluoropolymers、sterilant gas、2%、aerosol propellants、food freezant、1%、other、8%、exports、3% (1985)、fluorocarbons、U.S. Production: 2023: 70、000、000 - <85、000 lb、2022: 70、2021: 100、000 - <250、2020: 85、000 - <100、Non-confidential 2012 Chemical Data Reporting (CDR) information on the production and use of chemicals manufactured or imported into the United States.
