20140336424 - Method for producing trans-1-chloro-3,3,3-trifluoropropene: Provided is a method for producing trans-1-chloro-3,3,3-trifluoropropene usable as a raw material for a foaming agent for a hard polyurethane foam, a solvent, a cleaning agent, a cooling medium, a working fluid, a propellant, a fluorinated resin, etc., the method involving a step of bringing cis-1-chloro-3,3,3-trifluoropropene into contact with a... Agent:

20140336425 - Process for the production of tetrachloromethane: Processes for the production of tetrachloromethane are provided. The present processes involve catalyzing the chlorination of a feedstream comprising partially chlorinated methanes with a free radical initiator. Cost savings are thus provided relative to conventional processes that require the use of high temperatures and/or pressures, and safety concerns are alleviated... Agent: Dow Global Technologies LLC

20140336426 - Process and apparatus for heat recovery in vinyl chloride monomer plants or in integrated vinyl chloride monomer or polyvinyl chloride plants: Disclosed is a process and apparatus for heat recovery in vinyl chloride monomer manufacturing plants or in integrated vinyl chloride monomer/polyvinyl chloride manufacturing plants. A process for capture and use of excess heat recovered in the production of vinyl chloride includes distillatively purifying DCE in a high-boilers column, using a... Agent: Thyssenkrupp Industrial Solutions Ag

  
11/06/2014 > 1 patent applications in 1 patent subcategories.

20140330051 - Catalytic gas phase fluorination of 1,1,2-trichloroethane and/or 1,2-dichloroethene to produce 1-chloro-2,2-difluoroethane: The invention is directed to a catalyst for the gas phase fluorination of 1,1,2-trichloroethane and/or 1,2-dichloroethene with HF to give 1-chloro-2,2-difluoroethane which catalyst is prepared by co-depositing FeCl3 and MgCl2 on chromia-alumina, or co-depositing Cr(NO3)3 and Ni(NO3)2 on active carbon, or by doping alumina with ZnCl2, and to a process... Agent: Bayer Intellectual Property Gmbh

  
10/30/2014 > 2 patent applications in 1 patent subcategories.

20140323775 - Process for the production of chlorinated alkanes: Processes for the production of chlorinated alkanes are provided. The present processes comprise catalyzing the addition of at least two chlorine atoms to an alkane and/or alkene with a catalyst system comprising one or more nonmetallic iodides and/or lower than conventional levels of elemental iodine and at least one Lewis... Agent: Dow Global Technologies LLC

20140323776 - Process for the production of chlorinated alkanes: Processes for the production of chlorinated alkanes are provided. The present processes comprise catalyzing the chlorination of a feedstream comprising one or more alkanes and/or alkenes with a catalyst system comprising one or more inorganic iodine salts and/or lower than conventional levels of elemental iodine and at least one Lewis... Agent: Dow Global Technologies LLC

  
10/23/2014 > 3 patent applications in 3 patent subcategories.

20140316169 - Process for producing 2,3,3,3-tetrafluoropropene: The present invention discloses a manufacturing process to produce high purity 1234yf from 245eb, which preferably includes the removal of impurities present in 245eb raw material, the dehydrofluorination of 245eb, and the removal of impurities present in final crude product. The disclosed manufacturing process allows the production of a 1234yf... Agent:

20140316170 - Process for producing 2,3,3,3-tetrafluoropropene: The present invention relates, in part, to the discovery that the presence of impurities in 1,1,2,3-tetrachloropropene (1230xa) results in catalyst instability during the fluorination of 1230xa to 2-chloro-3,3,3-trifluoropropene. By substantially removing the impurities, it is shown that the catalyst life is extended and results in improved operation efficiency of the... Agent:

20140316171 - Process for the manufacture of hydrofluoroolefins: The invention relates to a process for manufacturing 1,1,1,2-tetrafluoropropene (1234yf, CF3-CF═CH2) from 1,1,3,3-tetrachlororopropene (1230za, CCl2CH—CHCl2) and/or 1,1,1,3,3-pentachloropropane (240fa, CCl3CH2CHCl2). The process comprises a step of isomerization of 1,1,3,3-tetrafluoropropene (1230za) to 1,1,2,3-tetrachloropropene (1230xa) followed by conversion of the 1,1,2,3-tetrachloropropene (1230xa) to 1,1,1,2-tetrafluoropropene (1234yf) via a hydrofluorination process....
