Usage

General Description

1,2,3,3,3-Pentafluoropropene is a chemical compound with the molecular formula C3H2F5. It is a colorless gas at room temperature and is commonly used as a refrigerant and in the production of hydrofluoroolefins. Pentafluoropropene is a highly stable compound, resistant to oxidation and heat, and is considered to have a low toxicity level. It is also used in the manufacturing of specialty polymers and as a solvent in the electronics industry. However, because of its potential as a greenhouse gas, there are ongoing efforts to find alternative, more environmentally friendly compounds for its applications.

Selective Hydrodefluorination of Hexafluoropropene to Industrially Relevant Hydrofluoroolefins

The selective hydrodefluorination of hexafluoropropene to HFO-1234ze and HFO-1234yf can be achieved by reaction with simple group 13 hydrides of the form EH3 ? L (E=B, Al; L=SMe2, NMe3). The chemoselectivity varies depending on the nature of the group 13 element. A combination of experiments and DFT calculations show that competitive nucleophilic vinylic substitution and addition-elimination mechanisms involving hydroborated intermediates lead to complementary selectivities. (Figure presented.).

Process for preparation of 1,2,3,3,3-pentafluoropropene from hexafluoropropene

The invention belongs to the technical field of preparation of pentafluoropropylene, and particularly relates to a method for preparing 1,2,3,3,3-pentafluoropropylene from hexafluoropropylene. According to the method, hexafluoropropylene and hydrogen are taken as raw materials, and 1,2,3,3,3-pentafluoropropylene is prepared through direct one-step reaction under the action of a solid mixture catalyst; the solid mixture catalyst is a mixture of one or more of oxyhalides of transition metals, IIA and IIIA group metals or derivatives thereof and a VIII group metal-based compound. Compared with amethod for preparing 1,2,3,3,3-pentafluoropropylene from hexafluoropropylene through a hydrogenation and HF removal two-step method, the solid mixture catalyst used in the method provided by the invention has higher pentafluoropropylene selectivity and reaction stability.

Method for the 1,2,3,3,3-pentafluoropropene production

In the present invention from a number 1, 2, 3, 3, 3 - pentafluoropropene (HFO provided 1225ye) hexafluoropropylene (HFP) method for bath a number [...] substrate. The upper index 2, 3, 3, 3 - 1, 2, 3, 3, 3 - pen hit [phul [phul] base oro pro pen phenolic resin foam which is very low it is a coolant 1234ze (HFO provided 1234yf) HFP H2S-free capacity as an intermediate of a hydrogenating catalyst 1, 1, 2, 3, 3, 3 - hexafluoropropane (HFC-a 236ea) is patterned to expose a hydrogen on generating; reacting a hydrogen fluoride catalyst obtained in said HFC provided 236ea and subjected to a high pressure liquid coolant bath of hydrogen fluoride in an HFO provided 1225ye number number 2000. Reacting a number when a HFC-a 236ea HFP hydrogen and vapor phase high pressure liquid coolant, reaction properly time to prevent the hydrogen consumed only unreacted hydrogen separation and circulating process can be eliminated, such as returning excess of hydrogen by a prefilled billion number. In hydrogenation of the resulting gaseous products another separation step (HFC-a 236ea) followed by a high pressure liquid coolant vapor reaction directly without a perhalogenated alkyl HFO provided 1225ye number 2000. In addition in the present invention HFP hydrogenation reaction temperature and number of stand-alone Dichlorethane efficiently number for the HFC-a 236ea perhalogenated reactions the method generates a control hydrogenation cycled in an HFC-a 236ea surfaces have diameters less than 2000.
