Abstract: Disclosed are processes for a high temperature isomerization reaction converting (E)-1-chloro-3,3,3-trifluoropropene to (Z)-1-chloro-3,3,3-trifluoropropene. In certain aspects of the invention, such a process includes contacting a feed stream with a heated surface, where the feed stream includes (E)-1-chloro-3,3,3-trifluoropropene or mixture of (E)-1-chloro-3,3,3-trifluoropropene with (Z)-1-chloro-3,3,3-trifluoropropene. The resulting product stream includes (Z)-1-chloro-3,3,3-trifluoropropene and (E)-1-chloro-3,3,3-trifluoropropene, where the ratio of (Z) isomer to (E) isomer in the product stream is higher than the ratio feed stream. The (E) and (Z) isomers in the product stream may be separated from one another.

Abstract: The present invention is in the field of organic and natural product chemistry. The present invention relates to an efficient process for purification, simultaneous extraction, and separation of monohydroxycarotenoids from dihydroxycarotenoids in various natural products or in synthetic mixtures. Similarly, the process can also be applied to the simultaneous extraction, saponification, and separation of esterified mono- and dihydroxycarotenoids in natural products and their oleoresins or in their synthetic mixtures. Therefore, esterified and unesterified monohydroxycarotenoids such as (3R)-?-cryptoxanthin and (3R,6?R)-?-cryptoxanthin can be efficiently separated from their corresponding dihydroxycarotenoids such as (3R,3?R,6?R)-lutein and (3R,3?R)-zeaxanthin that are found in various plants or in synthetic mixtures.

Abstract: The present invention relates, in part, to the discovery that high temperatures during the fluorination of 1,1,2,3-tetrachloropropene (HCO-1230xa) to 2-chloro-3,3,3-trifluoropropene (HCFO-1233xf) results in catalyst instability, reduced selectivity of the conversion, and/or the formation of one or more undesirable by-products. By controlling the reaction temperature, it is shown that the catalyst life may be extended and the selectivity of the reaction improved. Such control similarly results in an overall improvement in the production of certain hydrofluoroolefins, particularly 2,3,3,3-tetrafluoropropene (HFO-1234yf).
