| 应用领域 | Uses: HCFCs: Used as refrigerants、blowing agents、cleaning agents、and fire extinguishing agents (CFC alternatives)、[HSDB]、Used as a refrigerant in air conditioners、a fire extinguisher、a foam blowing agent、and a metal cleaner、[HSDB] Developed as a chlorofluorocarbon replacement、[AIHA]、Metal Degreasing [Category: Clean]、Refrigerant in low pressure chillers for air conditioning systems、in portable fire extinguishers for the fire protection industry、heat transfer agent、solvents. Refrigerant to replace CFC11 in commercial chillers and air conditioning units.、Air conditioning、fire fighting (potential application)、Industry Uses: Flame retardant、Not Known or Reasonably Ascertainable、Refrigerants、Consumer Uses: Refrigerants、Methods of Manufacturing: ... Made by the fluorination of tetrachloroethylene with either liquid or gaseous HF.、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: 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、Common impurities reported in several samples of HCFC-123:[Table#6242]、U.S. Production: 2023: 1、000、000 - <5、000 lb、2022: 1、2021: 550、000 - <1、2020: 1、A small amount of HCFC-123 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-123 is scheduled by 2020.、Ethane、2、2-dichloro-1、1、1-trifluoro- 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).、Production volume for non-confidential chemicals reported under the 2006 Inventory Update Rule. Chemical: Ethane、1-trifluoro-. Aggregated National Production Volume: 10 to < 50 million lbs.、For more U.S. Production (Complete) data for 2、2-DICHLORO-1、1-TRIFLUOROETHANE (6 total)、please visit the HSDB record page.、General Manufacturing Information: Not Known or Reasonably Ascertainable、All Other Chemical Product and Preparation Manufacturing、Electrical Equipment、Appliance、and Component Manufacturing、1-trifluoro-: ACTIVE、SRP: The EPA has organized groups of chemicals into two classes according to their ozone-depletion potential. Class I controlled substances are those with an ozone-depletion potential of 0.2 or higher. Class II controlled substances are those with an ozone-potential of less than 0.2. Class II controlled substances are all hydrochlorofluorocarbons (HCFCs).、Class II controlled substances are compounds that have an ozone depletion potential (ODP) less than 0.2、and are all hydrochlorofluorocarbons (HCFCs). HCFCs were developed as transitional substitutes for Class I substances and are subject to a later phaseout schedule than Class I substances. ... Although there are currently 34 controlled HCFCs、only a few are commonly used. The most widely used have been HCFC-22 (usually a refrigerant)、HCFC-141b (a solvent and foam-blowing agent)、and HCFC-142b (a foam-blowing agent and component in refrigerant blends). ... As a Party to the Montreal Protocol、the U.S. must incrementally decrease HCFC consumption and production、culminating in a complete HCFC phaseout in 2030. The major milestones that are upcoming for developed countries are a reduction in 2010 to at least 75 percent below baseline HCFC levels and a reduction in 2015 to at least 90 percent below baseline. Section 605 of the Clean Air Act sets the U.S. phaseout targets for Class II substances. In 1993、the EPA established the phaseout framework and the "worst-first" approach that focused first on HCFC-22、HCFC-141b、and HCFC-142b because these three HCFCs have the highest ODPs of all HCFCs. To meet the required 2004 reduction、the EPA phased out HCFC-141b in 2003 and froze the production and consumption of HCFC-22 and HCFC-142b. In 2009、EPA reduced the production and import of virgin HCFC-22 and HCFC-142b and limited the use of those compounds to meet the Montreal Protocol's 2010 milestones.、The numbers in the "ODP1" column are from the Montreal Protocol. Some numbers have been updated as per amendments to the protocol. The "ODP2" column numbers are from the stratospheric ozone protection regulations at 40 CFR Part 82、as required by Title VI of the Clean Air Act amendments. These numbers include the amendments of July 18、2003 (68 FR 42892). Data in the "ODP3" column come from WMO's、World Meteorological Organization、Scientific Assessment of Ozone Depletion: 2006. ODP values listed are semi-empirical and can be found in Table 8-1 of the document. All GWP values represent global warming potential over a 100-year time horizon. The numbers in the "GWP1" column are from Table 1-6 of The Scientific Assessment of Ozone Depletion、2002、a report of the World Meteorological Association's Glo |
