摘要： The present disclosure provides a method for purifying HFO-1132 to a high purity while suppressing the isomerization and loss of HFO-1132. Specifically, the present disclosure provides a method for purifying 1,2-difluoroethylene, which is HFO-1132, the method comprising, in this order, step 1 of bringing a composition comprising trans-1,2-difluoroethylene, which is HFO-1132(E), and water into contact with a zeolite having an average pore size of 2 to 4 Å to reduce the water content from the composition; and step 2 of recovering a purified product containing HFO-1132(E) and a reduced content of water, and containing less than 0.1% by volume of HFO-1132 (Z).

摘要： This invention pertains to a method for removing acidic impurity from halogenated olefins, especially methods for removing acidic impurity from halogenated propenes, and even more particularly to methods for removing acidic impurity from 1,3,3,3-tetrafluoro-1-propene (HFO-1234ze), 2,3,3,3-tetrafluoro-1-propene (HFO-1234yf), 1-chloro-3,3,3-trifluoro-1-propene (HCFO-1233zd), and 2-chloro-3,3,3-trifluoro-1-propene (HCFO-1233xf). The method is conducted by passing the halogenated olefin stream, in liquid or gas form, through a solid adsorbent bed, which contains at least one acid reactive agent.

摘要： The present disclosure provides separation processes that use azeotropic or azeotropic-like compositions of 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd) that allow for improved recovery rates of 1-chloro-3,3,3-trifluoropropene during or after manufacturing processes. Such recovery or separation processes can utilize the unique properties of azeotropic or azeotropic-like composition with various combinations of separation techniques (e.g., distillation and decanting) that yield highly pure compositions of 1-chloro-3,3,3-trifluoropropene and simultaneously offer high yields of 1-chloro-3,3,3-trifluoropropene. Such highly pure compositions of 1-chloro-3,3,3-trifluoropropene may find useful applications in polymer technology as monomers or comonomers.

摘要： Disclosed are the combinations containing Z and E stereoisomers of hydrofluoroolefins where the more toxic isomer is less than about 30% weight of the combination (vs the sum of Z+E), to minimize the toxicity impact in the applications they will be used for such as cooling and heat fluids, foams blowing agents or solvents. Also disclosed are means to obtain combinations containing Z and E stereoisomers of hydrofluoroolefins.

摘要： Disclosed is a process to dry 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd) or its mixtures by washing with water and or alkaline solution. The resulting liquid mixture, containing HCFO-1233zd, other organic, and water, is allowed to settle, and thereafter, the lighter water layer is decanted off from the top of the mixture. The heavier HCFO-1233zd layer is then withdrawn from the bottom of the decanter to a desiccant dryer (e.g., molecular sieve, activated alumina, silica gel, and the like) to further remove the residual soluble moisture from the HCFO-1233zd to about 80 ppm or less.
