2,3,3,3-Tetrafluoro-1-propylene (HFO-1234yf), as a single working fluid refrigerant, has excellent environmental parameters and good refrigeration performance, making it a promising next-generation automotive refrigerant alternative.
Using carbon tetrachloride and ethylene as raw materials, CCl3CH2CH2Cl is generated by polymerization of CCl4 and ethylene, then CCl3CHClCH2Cl is obtained by chlorination, and under catalytic conditions, fluorine-chlorine exchange and de-HF can be carried out to obtain the final product 2,3,3,3-tetrafluoro-1-propene.
