Usage

Description

1,1,1,3,3-Pentafluoropropane, also known as HFC 245fa, is a colorless gas with chemical properties that make it suitable for various applications. It is a hydrofluorocarbon (HFC) compound, which is a type of refrigerant and foam-blowing agent that has been developed as a more environmentally friendly alternative to fully halogenated chlorofluorocarbons.

Uses

Used in Foam Industry:
1,1,1,3,3-Pentafluoropropane is used as a foam-blowing agent for the production of various types of foam, such as polyurethane and polystyrene. It is chosen for this application due to its ability to act as a blowing agent, which helps create the desired cellular structure in the foam.
Used in Refrigeration Industry:
1,1,1,3,3-Pentafluoropropane is used as a refrigerant in various cooling systems, including air conditioning and refrigeration units. It is selected for this purpose because of its thermodynamic properties, which allow for efficient heat transfer and cooling performance.
Used in Environmentally Friendly Applications:
1,1,1,3,3-Pentafluoropropane is used as an environmentally friendly alternative to fully halogenated chlorofluorocarbons (CFCs) in various industries. It is chosen for this application because it has a lower global warming potential (GWP) and ozone depletion potential (ODP) compared to CFCs, making it a more sustainable choice for reducing the environmental impact of refrigeration and foam production processes.

Preparation method of Z-1-halogen-3, 3, 3-trifluoropropene

The invention discloses a preparation method of Z-1-halogen-3, 3, 3-trifluoropropene. The preparation method comprises the following steps: in the presence of a block catalyst, E-1-halogen-3, 3, 3-trifluoropropene is subjected to a gas phase isomerization reaction in a tubular reactor to obtain Z-1-halogen-3, 3, 3-trifluoropropene, and halogen is fluorine or chlorine. According to the preparation method, 1, 1, 1, 3, 3-pentachloropropane is used as an initial raw material, Z-1-chloro-3, 3, 3-trifluoropropene or Z-1, 3, 3, 3-tetrafluoropropene secondary product is prepared through a gas-phase fluorination reaction and an isomerization reaction, the materials which are not completely reacted are independently circulated through a gas-phase independent circulation process so that the initial raw materials can be almost completely converted into the target product, and finally, the target product is extracted from a process system, and thus liquid waste and waste gas are not generated, and green production is realized.

A structural, mechanistic, and kinetic study of the dehydrofluorination of 1,1,1,3,3-pentafluoropropane in the absence of catalyst

The catalyst-free dehydrofluorination of 1,1,1,3,3-pentafluoropropane (HFC-245fa) was investigated both experimentally and theoretically to elucidate the mechanism and kinetics of the reaction. The experimental results demonstrated easier generation of E-1,3,3,3-tetrafluoropropene (HFO-1234ze(E)) than HFO-1234ze(Z) under the same reaction conditions within a temperature range of 500–700 °C. When analyzing the geometry, energetics, and kinetic modeling of the reaction at the B3LYP/6?311++G (d,p) level of theory, it was found that the thermodynamic stability of HFO-1234ze(E) is relatively higher than its isomer (HFO-1234ze(Z). Besides, the rate constants of HFO-1234ze(E) were always larger than those of HFO-1234ze(Z) at 400–2000 K, which agreed well with the higher selectivity of HFO-1234ze(E) in the synthetic experiment results. Our theoretical demonstration provides a reference to investigate the mechanism and kinetics of other analogous reactions.
