08/21/2014 > 5 patent applications in 5 patent subcategories.

20140235903 - Process for producing 2,3,3,3-tetrafluoropropene: The present invention relates, in part, to the discovery that the presence of impurities in a reactor for dehydrochlorinating HCFC-244bb to HFO-1234yf results in selectivity changeover from HFO-1234yf to HCFO-1233xf. By substantially removing such impurities, it is shown that the selectivity to HFO-1234yf via dehydrochlorination of HCFC-244bb is improved.... Agent: Honeywell International Inc.

20140235904 - Process for producing 2,3,3,3-tetrafluoropropene: 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... Agent: Honeywell International Inc.

20140235905 - Method for the synthesis of low cost initiators for telechelic polyisobutylenes: A method for the synthesis of 1,3-di(chloropropyl)-5-tert-butyl benzene includes the steps of conducting Friedl-Crafts alkylation of 1,3-diisopropyl benzene by tert-butyl chloride in the presence of an alkylation catalyst to obtain 1-tert-butyl-3,5-diisopropylbenzene; peroxidizing the 1-tert-butyl-3,5-diisopropyl benzene by gaseous oxygen in the presence of a peroxidation catalyst in a basic solution to... Agent: The University Of Akron

20140235906 - Process to make 1,1,2,3-tetrachloropropene from 1,1,3-trichloropropene and/or 3,3,3- trichloropropene: Disclosed is a process for the synthesis of 1,1,2,3-tetrachloropropene (HCC-1230xa) using 1,1,3-trichloropropene (HCC-1240za) and/or 3,3,3-trichloropropene (HCC-1240zf) and Cl2 gas as the reactants, wherein the process takes place in a single reactor system. Before this invention, HCC-1230xa was made in a two-step process using HCC-1240za/HCC-1240zf and Cl2 gas, and the processing... Agent: Honeywell International Inc.

20140235907 - Methods for the dehydrochlorination of 1,1,1,3-tetrachloropropane to 1,1,3-trichloropropene: This invention relates to a method to improve 1,1,3-trichloropropene selectivity in HCC-250fb (1,1,1,3-tetrachloropropane) dehydrochlorination. In normal practice, FeCl3 is used as the catalyst for the dehydrochlorination of HCC-250fb to produce 1,1,3-tri-chloropropene. In this invention as source of water is added into the reaction system to inhibit the formation of high... Agent: Honeywell International Inc.

08/14/2014 > 4 patent applications in 4 patent subcategories.

20140228600 - Process for the manufacture of hydrochlorofluoroolefins: The invention also relates a process for the manufacture of trans 1-chloro3,3,3-trifluoropropene. The process comprises an isomerization step from cis 1233zd to trans 1233zd.... Agent: Arkema Inc.

20140228601 - Methods for recovering chlorinated hydrocarbons: Processes for isolating 1,1,1,2,3-pentachloropropane from a crude product stream containing the 1,1,1,2,3-pentachloropropane and ferric chloride. The processes may include deep distillation of the crude, treatment of the crude with a reagent that deactivates the ferric chloride followed by distillation on the deactivated crude stream, aqueous washing of the crude product... Agent:

20140228602 - Catalyst and method for its preparation: A catalyst including gold, or a compound thereof, and sulphur, a compound of sulphur, trichloroisocyanuric acid or a metal dichloroisocyanurate on a support, together with a process for manufacturing the catalyst and its use in a chemical process are described.... Agent: Johnson Matthey Public Limited Company

20140228603 - Process for converting gaseous alkanes to liquid hydrocarbons: Embodiments disclose a process for converting gaseous alkanes to higher molecular weight hydrocarbons, olefins or mixtures thereofs wherein a gaseous feed containing alkanes may be reacted with a dry bromine vapor to form alkyl bromides and hydrobromic acid vapor. The mixture of alkyl bromides and hydrobromic acid then may be... Agent: Marathon Gtf Technology, Ltd.
