Title:
PREPARATION OF AN IMPROVED COMPOSITION FROM 1-CHLORO-3, 3, 3-TRIFLUOROPROPENE (HFO-1233ZD) HIGH BOILING RESIDUE BY-PRODUCT
Document Type and Number:
WIPO Patent Application WO/2023/141794
Kind Code:
A1
Abstract:
High boiling fluorinated by-products obtained from a manufacturing process of 1-chloro-3, 3, 3-trifluoropropene (HFO-1233zd) not only include components that can be used as a starting material or feedstock in the production of 1, 1, 1, 3, 3-pentafluoropropane (HFC-245fa), but also contain impurities that can be detrimental in the HFC-245fa process. A method of providing an improved composition from the high boiling by-products obtained from an HFO-1233zd manufacturing process reduces these impurities. The improved composition can be used as a starting material or feedstock for the production of HFC-245fa.
