12/18/2014 > 1 patent applications in 1 patent subcategories.

20140371494 - Process for the production of chlorinated propanes and propenes: Processes for the production of chlorinated propanes and propenes are provided. The present processes comprise catalyzing at least one chlorination step with one or more regios elective catalysts that provide a regioselectivity to one chloropropane of at least 5:1 relative to other chloropropanes.... Agent:

12/11/2014 > 3 patent applications in 3 patent subcategories.

20140364657 - Process for reactor passivation: Disclosed is a process for passivating a surface of a dehydrochlorination reactor comprising: stopping a flow of hydrochlorofluoropropane to a reactor, passing a gas mixture comprising hydrogen gas through the reactor at a temperature of at least 25° C. for a period of time sufficient to restore the selectivity of... Agent: E.i. Du Pont De Nemours And Company

20140364658 - Method for preparing fluorinated olefin compounds: The present invention relates to a method for preparing fluorinated olefin compounds, in particular (chloro)fluoropropenes and (chloro)fluorobutenes, and specifically, the fluorinated compound 2,3,3,3-tetrafluoro-1-propene, including at least one step of fluorination, in the gaseous phase, with HF and at least one compound selected from the halopropenes having formula the CX3CHClCH2X and... Agent:

20140364659 - Process for the conversion of isomeric mixture of dichlorodiphenyl sulfones to chlorobenzene: The invention relates to a process for the single step conversion of isomeric mixture of dichlorodipheriyi sulfones to chlorobenzene. The invention further relates a process of using dilute sulfuric acid and re-circulating the dilute sulfuric acid.... Agent:

12/04/2014 > 2 patent applications in 2 patent subcategories.

20140357906 - Method and system for producing nitrobenzene: A method of manufacturing a fluorine-containing aromatic compound represented by the following formula (2-1) or formula (2-2): [R is a hydrogen atom, an alkyl group having a carbon number of 1 to 12 which may have a substituent other than a fluorine atom, or a monovalent aromatic group which may... Agent:

20140357907 - Process for producing 1,2-dichloro-3,3,3-trifluoropropene: (In the formula, X represents a fluorine atom, chlorine atom or bromine atom.) is reacted with chlorine in a gas phase in the presence of a catalyst. It is possible by this process to produce 1,2-dichloro-3,3,3-trifluoropropene in an industrial scale with good yield by using 1-halogeno-3,3,3-trifluoropropene, which is available with... Agent: Central Glass Company, Limited

11/27/2014 > 4 patent applications in 3 patent subcategories.

20140350309 - 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 a reduced conversion rate and/or a selectivity changeover from HFO-1234yf to HCFO-1233xf. By substantially removing such impurities, it is shown that the conversion rate may be... Agent: Honeywell International Inc.

20140350310 - Catalytic process of making 1,3,3,3-tetrafluoropropene: This disclosure relates to processes of making 1,3,3,3-tetrafluoropropene. The processes involve dehydrofluorinating 1,1,1,3,3-pentafluoropropane in vapor phase in the presence of a catalyst comprising a metal compound supported on alumina to produce a product mixture comprising 1,3,3,3-tetrafluoropropene, wherein said metal compound is selected from the group consisting of salts of sodium,... Agent: E I Du Pont De Nemours And Company

20140350311 - Method for producing fluorinated organic compounds: i

20140350312 - Method for preparing 2,3,3,3-tetrafluoropropene: Provided are a fluorination catalyst for preparing 2,3,3,3-tetrafluoropropene and a method using the catalyst for preparing 2,3,3,3-tetrafluoropropene. The catalyst has the following structural formula: Crx(Y,Z)0.005-0.5O0.1-10F1.0-3.0, where Y is one or a combination of two or more among Al, Zn, and Mg, and where Z is a rare earth element having...
