Process for hydrogenation of carboxylic acids and derivatives to hydrocarbons
-
Page/Page column 7-8, (2008/06/13)
A process for hydrogenating a carboxylic acid and/or derivative thereof having a carboxylate group represented by the general formula R1COO-, which process comprises feeding hydrogen and the carboxylic acid and/or derivative thereof to a reactor and maintaining conditions within the reactor such that hydrogen reacts with the carboxylic acid and/or derivative thereof to produce a product stream comprising carbon dioxide, carbon monoxide, methane and hydrocarbons represented by general formulae R1H and R1CH3, characterised in that the molar ratio of R1H : R1CH3 is above a pre-determined value and/or the mole ratio of the sum of carbon dioxide, carbon monoxide and methane to carboxylate groups is above a pre-determined value.

Rhodococcus sp.BPM 1613, a pristane oxidizing microorganism, grows on isoprenoid hydrocarbons such as phytane (2,6,10,14-tetramethylhexadecane), norpristane (2,6,10-trimethyl-pentadecane) and farnesane (2,6,10-trimethyldodecane) as the sole carbon source, resulting in accumulation of oxidation products in the culture broth.The oxidation products of phytane, norpristane and farnesane in the respective culture broth were isolated and purified by the use of silica gel column chromatography.Their chemical structures were determined by instrumental analyses such as IR, NMR and mass spectrometry.The oxidation products of phytane were identified as 2,6,10,14-tetramethyl-1-hexadecanol and 2,6,10,14-tetramethylhexadecanoic acid, the product of norpristane as 2,6,10-trimethyl-1-pentadecanol, and that of farnesane as 2,6,10-trimethyl-1-dodecanol.All these oxidation products were either monoalcohols or monocarboxylic acids derived through oxidation of the isopropyl terminus of each alkane.In addition, the relationship between the terminal structure of isoprenoid hydrocarbons and microbial oxidation was explored on the basis of these results.
