1,1,1,2-Tetrafluoroethane
1. Basic Information
Name: 1,1,1,2-Tetrafluoroethane
Alias: HFC-134a, R134a
CAS No.: 811-97-2
Molecular Formula: C2H2F4
Molecular Weight: 102.03
Category: Hydrofluorocarbon refrigerant, aerosol propellant, foam blowing agent, heat transfer medium, cleaning agent raw material
2. Physical and Chemical Properties
Physical Properties
- Appearance: Colorless gas under normal temperature and pressure, colorless transparent liquid under pressurized liquefaction
- Odor: Almost odorless, slight faint ether odor at high concentration
- Solubility: Slightly soluble in water; miscible with mineral oil, alcohol, ether, hydrocarbon solvents
- Boiling Point: -26.1 ℃
- Density (liquid 25℃): 1.206 g/cm3
- Vapor Pressure (25℃): ~666 kPa
- Hygroscopy: Non-hygroscopic
- Aqueous property: Neutral gas, no hydrolysis at room temperature, stable in water
Chemical Properties
- Molecular structure: Ethane skeleton with four fluorine substitutions, no chlorine atoms, zero ozone depletion potential
- Thermal stability: Stable below 180 ℃; high temperature above 250 ℃ decomposes to produce hydrogen fluoride toxic gas
- Chemical inertness: Does not react with metals, plastics, rubber under normal use temperature; inert to acid and weak alkali
- Combustion characteristic: Non-flammable under normal pressure, does not support combustion; high temperature cracking generates corrosive HF
- Photostability: Decomposes slowly in high-altitude atmosphere, low greenhouse effect compared with CFCs
- Compatibility: Compatible with POE/PVE refrigeration lubricating oil; incompatible with strong alkali, molten metal, high-temperature open flame
3. Main Application Fields
1. Automobile & Commercial Refrigerant (Core Application)
Environmentally friendly replacement for R12; used in car air conditioners, household refrigerators, central air conditioning, cold storage equipment
2. Aerosol Propellant
Propellant for cosmetics, medical spray, industrial aerosol instead of ozone-depleting CFC
3. Polyurethane Foam Blowing Agent
Low-ODP foaming auxiliary for rigid thermal insulation foam
4. Electronic Precision Cleaning & Heat Transfer Medium
Low-toxicity cooling medium for semiconductor equipment, precision parts cleaning solvent
