Process of catalytic fluorination in liquid phase of product 1, 1, 1, 2, 3-pentachloropropane or/and 1,1,2,2,3- pentachloropropane into product 2-chloro-3, 3, 3-trifluoropropene in presence of a catalyst.
Abstract:
The present invention relates to formulated systems of 1-chloro-3,3,3-trifluoropropene (R-1233zd) and/or 2-chloro-3,3,3-trifluoropropene (R-1233xf) that are sufficiently thermally and chemically stable such that they can be effectively used sans additional stabilizers. The formulations of the present invention are particularly useful compositions for refrigeration, heat transfer, and foam pre-mixes.

Abstract:
In this invention we are disclosing a process for the synthesis of hydrocchlorofluoro olefins (HCFO) and/or hydrofluoroolefins (HFO). The process is based on the following steps of liquid phase, noncatalytic fluorination of hydrochloropropenes to form hydrochlorofluoropropenes and/or hydrofluoropropenes, followed by gas phase, noncatalytic fluorination of the hydrochlorofluoropropenes to form hydrofluoropropenes.
Abstract:
The present invention relates to blowing agent compositions comprising at least one hydrochlorofluoroolefin (HCFO) used in the preparation of foamable thermoplastic compositions. The HCFOs of the present invention include, but are not limited to, 1-chloro-3, 3,3-trifluoropropene (HCFO-1233zd), particularly the trans- isomer, 2-chloro-3,3,3-trifluoropropene (HCFO-1233xf), dichloro-fluorinated propenes, and mixtures thereof. The blowing agent compositions of the present invention are used with coblowing agents including carbon dioxide, atmospheric gases, hydrofluorocarbons (HFC), hydrofluoroolefins (HFO), alkanes, hydrofluoroethers (HFE), and mixtures thereof. Preferred HFCs used as coblowing agents in the present invention include, but are not limited too, 1,1,1,2-tetrafluoroethane (HFC-134a), 1,1-difluoroethane (HFC-152a), 1,1,1-trifluoroethane (HFC-143a), pentafluorethane (HFC-125), difluoromethane (HFC-32). The blowing agent compositions are useful in the production of low density insulating foams with improved k-factor.
