Manufacturing process for iodinated aromatic compounds

Номер: US20120059203A1
Автор: Han Seok Kim, Il Hoon Cha, Jong In Lee, Yoon Seo Lee
Принадлежит: SK Chemicals Co Ltd

Disclosed is a method for preparing an iodinated aromatic compound. More specifically, disclosed is a method of preparing an iodinated aromatic compound by iodinating an aromatic compound in the presence of oxygen over a zeolite catalyst, in which the aromatic compound and a monoiodo analog of the aromatic compound, or a monoiodo aromatic compound, as raw materials, are allowed to react with iodine. In comparison with a method in which only the aromatic compound is used as a raw material without adding the monoiodo compound, the disclosed method can increase the productivity of diiodo compounds and the selectivity to a p-diiodo compound and, at the same time, suppress side reactions, thus lengthening the life span of the catalyst.

Hydrogenation Process for Fluorocarbons

Номер: US20120134892A1
Автор: Gus Cerri, Haluk Kopkalli, Hsueh Sung Harry Tung, Orlando George Rodrigues, Stephen A. Cottrell, Yuon Chiu
Принадлежит: Honeywell International Inc

Disclosed is a process and apparatus for the catalytic hydrogenation of fluoro-olefins to fluorocarbons where the reaction is carried out in a multi-tube shell and tube reactor. Reactions involving hydrogenation of fluoro-olefins are typically exothermic. In commercial processes where a fluoro-olefin C n H 2n-x F x to C n H 2n-x2 F x is hydrogenated (e.g., hexafluoropropylene to 236ea, 1225ye to 245eb, and the like), inadequate management or control of heat removal may induce excess hydrogenation, decomposition and hot spots resulting in reduced yields and potential safety issues. In the hydrogenation of fluoro-olefins, it is therefore necessary to control the reaction temperature as precisely as practical to overcome challenges associated with heat management and safety.

Принадлежит: Marathon GTF Technology Ltd

A method is provided for converting gaseous lower molecular weight alkanes contained in a feed gas to liquid higher molecular weight hydrocarbons. One or more lower molecular weight alkanes contained in the feed gas, which are heavier than methane, are converted to methane in a pre-former reactor. The resulting methane-enriched gas has a methane fraction greater than the methane fraction of the feed gas. The methane-enriched gas and bromine are reacted to form alkyl bromide and the alkyl bromide is reacted in the presence of a catalyst to form the liquid higher molecular weight hydrocarbons and a residual gas. The liquid higher molecular weight hydrocarbons are recovered as product and the residual gas is fed to the pre-former reactor with the feed gas.

Process for making tetrafluoropropene

Номер: US20130211155A1
Автор: Andrew Joseph Poss, David Nalewajek, Haridasan K. Nair, Rajiv Ratna Singh
Принадлежит: Honeywell International Inc

The present invention describes a process for making CF 3 CH═CHF (HFO-1234ze). The process involves the addition of carbon tetrachloride (CCl 4 ) to 1,2-dichloroethylene to form CCl 3 CHClCHCl 2 . The compound CCl 3 CHClCHCl 2 thus can then either be treated with HF to produce CF 3 CHClCHClF as the main product, or it can be converted to CCl 2 ═CHCHCl 2 (1230za) by dechlorination. CCl 2 ═CHCHCl 2 can be treated with HF such that the main product obtained is CF 3 CHClCHClF. CF 3 CH═CHCl may be produced as a by-product, but upon treatment with HF, it affords the compound CF 3 CHClCHClF. The desired compound, CF 3 CH═CHF (HFO-1234ze), is obtained as a trans/cis mixture by dehydrochlorination of CF 3 CH 2 CHClF or by dechlorination of CF 3 CHClCHClF.

The process includes a combined liquid or vapor phase reaction/purification operation which directly produces (E) 1-chloro-3,3,3-trifluoro-propene (1233zd (E)) from these feed materials, which may also include 240fa. In the second liquid phase fluorination reactor 1233zd (E) is contacted with HF in the presence of catalyst to produce 1,1,1,3,3-pentafluoropropane (245fa) with high conversion and selectivity. A third reactor is used for dehydrofluorination of 245fa to produce (E) 1,3,3,3-tetrafluoro-propene (1234ze (E)) by contacting in the liquid phase with a caustic solution or in the vapor phase using a dehydrofluorination catalyst. This operation may be followed by one or more purification processes to recover the 1234ze (E) product.

The present invention provides a process of catalytic fluorination in gas phase of product 1,1,1,2,3-pentachloropropane or/and 1,1,2,2,3-pentachloropropane into product 2,3,3,3-tetrafluoropropene in presence of a catalyst. 122-. (canceled)23. A process of producing 2 ,3 ,3 ,3-tetrafluoropropene comprising contacting 1 ,1 ,1 ,2 ,3-pentachloropropane and/or 1 ,1 ,2 ,2 ,3-pentachloropropane with hydrogen fluoride in gas phase in the presence of a fluorination catalyst to produce 2 ,3 ,3 ,3-tetrafluoropropene.24. Process according to claim 23 , carried out in a single stage.25. Process according to claim 23 , wherein the product 2 claim 23 ,3 claim 23 ,3 claim 23 ,3-tetrafluoropropene is present at a concentration of at least 1%.26. Process of claim 23 , wherein said catalyst is a chromium catalyst.27. Process of claim 26 , wherein said catalyst further comprises a co-catalyst selected from the group consisting of Ni claim 26 , Co claim 26 , Zn claim 26 , Mn claim 26 , Mg and mixtures thereof claim 26 , and wherein said co-catalyst is present in an amount from about 1-10 wt % of said fluorination catalyst.28. Process of claim 23 , carried out in the presence of a catalyst comprising Ni—Cr.29. Process of claim 23 , wherein said catalyst is supported on a support comprising fluorinated alumina claim 23 , fluorinated chromia claim 23 , fluorinated activated carbon or graphite carbon.30. Process of claim 23 , wherein the fluorination catalyst is activated with a fluorine-containing compound.31. Process of claim 23 , in which the 1 claim 23 ,1 claim 23 ,1 claim 23 ,2 claim 23 ,3-pentachloropropane contains up to 40 mol % of isomer 1 claim 23 ,1 claim 23 ,2 claim 23 ,2 claim 23 ,3-pentachloropropane.32. Process of claim 23 , which is carried out at a pressure from 3 to 20 bars.33. Process of claim 23 , carried out at a temperature of from 200 to 450° C.34. Process of claim 23 , carried out with a contact time from 6 to 100 sec.35. Process of claim 23 , carried out with a ...

A process comprising feeding bromine into a first reactor; feeding low molecular weight alkanes into the first reactor; and withdrawing alkyl bromides from the first reactor wherein the bromine and low molecular weight alkanes are fed through an apparatus that rapidly mixes the bromine and low molecular weight alkanes. A process is disclosed further comprising reacting the alkyl bromides to form aromatic hydrocarbons.
