What are the main uses of trifluoropropene
info：m.crimea-realty.net | Release time：2025-09-16
Trifluoropropene (common types such as 1,3,3-tetrafluoropropene, also known as HFO-1234ze); Or 2,3,3,3-tetrafluoropropene, also known as HFO-1234yf, although its name contains "tetrafluoroethylene", it belongs to the core compound of fluorinated propylene and is often classified as a derivative system of trifluoropropene in practical applications. It is a type of fluorinated olefin with low global warming potential (GWP) and zero ozone depletion potential (ODP), and its applications are highly focused on environmental substitution and chemical synthesis. The specific application scenarios are as follows:
1、 Core application: Environmentally friendly refrigerant/foaming agent (replacing traditional fluorinated compounds)
This is the most mainstream use of trifluoropropene (especially HFO-1234ze/yf), which solves the problem of traditional fluorine-containing substances (such as fluorocarbons, HFCs) damaging the ozone layer or exacerbating the greenhouse effect, in line with global environmental regulations such as the Montreal Protocol and the Paris Agreement.
1. Environmentally friendly refrigerants
Alternative objects: Traditional refrigerants such as R134a (HFC class, with a GWP of about 1430 and significant greenhouse effect), R22 (Freon class, ODP>0， It has been gradually phased out.
Application Scenario:
Automotive air conditioning: HFO-1234yf is currently the mainstream alternative refrigerant in the global automotive industry and has been widely adopted by car companies such as BMW, Volkswagen, and General Motors. It can be directly adapted to existing air conditioning systems (with only minor adjustments to component compatibility), with a cooling efficiency close to R134a and a GWP of only 4 (far lower than R134a's 1430), resulting in a low greenhouse effect.
Commercial/household air conditioning/heat pump: HFO-1234ze is commonly used in commercial air conditioning (such as screw and centrifugal units), household split air conditioning, and air source heat pumps, especially suitable for public buildings with high environmental requirements (such as shopping malls and hospitals) and regions with strict environmental regulations such as the European Union and Japan. It is compatible with the lubricating oil and sealing materials of existing equipment and does not require large-scale system modification.
Cold chain logistics/refrigeration equipment: In supermarket refrigerators, cold chain transport vehicle refrigerated containers, and industrial low-temperature cold storage, trifluoropropene refrigerants can replace high GWP R404A (HFC class, GWP about 3922), while balancing low-temperature refrigeration performance (meeting -40 ℃ refrigeration needs) and environmental friendliness.
2. Environmentally friendly foaming agent
Alternative objects: Traditional foaming agents such as HCFC-141 (Freon class, ODP=0.11， Disabled), HFC-245fa (HFC class, GWP approximately 1030, gradually restricted).
Application Scenario:
Polyurethane foam (PU foam): used for building insulation materials (such as exterior wall insulation board, cold storage insulation layer), household appliances insulation layer (such as refrigerator, freezer box insulation), car seat/interior foam. As a foaming agent, trifluoroethylene (such as HFO-1234ze) can form a uniform and dense foam structure, with excellent thermal insulation performance (thermal conductivity as low as 0.022 W/(m ? K), which is equivalent to the traditional foaming agent), and no risk of ozone destruction in the foaming process. The GWP is only 1-5, which is the core choice of "low-carbon thermal insulation" in the current construction and household electricity industry.
Phenolic foam and polystyrene foam (EPS/XPS): In scenarios with high requirements for flame retardancy and high temperature resistance (such as pipe insulation and ship insulation), trifluoropropylene can replace some high GWP foaming agents to improve the flame retardancy and dimensional stability of foam.
2、 Important use: Intermediate for chemical synthesis
The carbon carbon double bonds and fluorine atoms contained in trifluoropropyl molecules have high reactivity and are key intermediates for synthesizing high-value fluorinated chemicals, widely used in fields such as medicine, pesticides, and functional materials.
1. Pharmaceutical intermediates
Used for synthesizing fluorine-containing drug molecules (such as antiviral drugs, anti-tumor drugs, anti-inflammatory drugs): The introduction of fluorine atoms can significantly enhance the lipid solubility, metabolic stability, and targeting of drugs ("fluorination effect"). For example, trifluoropropene can be synthesized into pharmaceutical intermediates containing trifluoromethyl (- CF ∝) or fluorinated cycloalkane structures through reactions such as addition, oxidation, and substitution.
2. Pesticide intermediates
Used for synthesizing highly efficient and low toxicity fluorinated pesticides (such as herbicides, insecticides, fungicides): Fluorinated pesticides have the characteristics of low dosage, strong targeting, and low toxicity to mammals. Trifluoropropene can be used as a precursor to synthesize fluorinated alkenes or trifluoromethyl pesticide active ingredients, such as "fluazinam" for controlling wheat aphids and "fluconazole" for controlling rice sheath blight. The key step requires the construction of fluorinated active groups using trifluoropropene as the raw material.
3. Functional material monomers
Synthesis of fluorinated polymers (such as fluororubber and fluororesin): Trifluoropropylene can be copolymerized with other fluorinated monomers (such as tetrafluoroethylene and hexafluoropropylene) to adjust the temperature resistance, corrosion resistance, and elasticity of the polymer. For example, its copolymers can be used to manufacture high-temperature resistant seals for automotive engines (above 200 ℃), corrosion-resistant linings for chemical pipelines, or high-frequency insulation materials in electronic devices, enhancing the stability of materials in extreme environments.
3、 Other potential uses
Fire extinguishing medium: Some derivatives of trifluoropropene (such as HFO-1234ze) have the characteristics of high fire extinguishing efficiency, non corrosion to equipment, and good environmental friendliness. They can replace traditional Halon fire extinguishing agents (ODP>0, already banned) or high GWP HFC fire extinguishing agents, and are used in fire extinguishing systems for precision scenarios such as electronic equipment rooms, data centers, and aerospace.
Aerosol propellant: in cosmetics (such as hair spray, shaving foam) and medical aerosols (such as asthma inhalers), it can replace the traditional Freon or propane/butane propellants, with both environmental protection and propulsion stability, and has no adverse effect on product composition.
