Method for preparing fatty alcohols with same carbon number by catalytic hydrodeoxygenation from fatty acid and/or fatty acid ester

The invention provides a method for preparing fatty alcohols with the same carbon number by catalytic hydrodeoxygenation from fatty acid and/or fatty acid ester. The method comprises the following step: in a reaction vessel, carrying out hydrodeoxygenation reaction on the fatty acid and/or fatty acid ester and hydrogen in the presence of a catalyst at a low temperature of 100-240 DEG C and under alow hydrogen pressure of 0.1-5 MPa to obtain desired fatty alcohol products with the same carbon number. According to the invention, the fatty alcohols with the same carbon number is prepared from the fatty acid and/or fatty acid ester through an active metal modified MeaXbAlc composite catalyst as defined herein. The method has the advantages of high conversion rate, good selectivity, mild reaction conditions, stable catalyst and the like, and has quite good industrial application prospect.

From esters to alcohols and back with ruthenium and osmium catalysts

There and back again: Hydrogenation of esters and the reverse reaction of dehydrogenative coupling of alcohols are efficiently catalyzed by dimeric complexes of Ru and Os under neutral conditions. The Os dimer (see picture) is an outstanding catalyst for the hydrogenation of alkenoates and triglycerides, and allows production of fatty alcohols from olive oil. This complex converts ethanol into ethyl acetate and hydrogen under reflux. Copyright

Reduction of aromatic and aliphatic esters using the reducing systems MoO2(acac)2 or V(O)(OiPr)3 in combination with 1,1,3,3-tetramethyldisiloxane

An efficient reduction of aromatic and aliphatic esters with 1,1,3,3-tetramethyldisiloxane in combination with [MoO2(acac) 2] or [V(O)(OiPr)3] is reported. In the former system, the presence of triphenylphosphane oxide allows high conversion and good isolated yield to be reached. For the latter system, no ligand is necessary to obtain the corresponding alcohols with similar results. 1,1,3,3-Tetramethyldisiloxane in association with [MoO2(acac)2] or [V(O)(OiPr)3] was found to efficiently reduce aliphatic and aromatic esters.

Synthesis of pyridinium amphiphiles used for transfection and some characteristics of amphiphile/DNA complex formation

Pyridinium amphiphiles have found practical use for the delivery of DNA into cells. Starting from 4-methylpyridine, a general synthesis has been devised for the production of pyridinium amphiphiles which allows variation in both the hydrophobic part and in the headgroup area of the compounds. By means of differential scanning microcalorimetry, zeta potential, particle size measurements and cryo electron microscopy, some characteristics of the pyridinium amphiphile/DNA complexes have been determined.

Quantitative Treatment of the Rotational Dynamics of Flexible-Chain Molecules. 13C NMR Relaxation Study of Hydrocarbon Chains Attached to the Fluorene Anchor

13C spin-lattice relaxation times (T1) and nuclear Overhauser enhancements (NOEs) were measured for individual carbons in flexible-chain molecules consisting of a hydrocarbon chain attached to fluorene moiety at position 3 through an ester bond.Quantitative treatment of the relaxation data of the ring carbons revealed an anisotropic motion for all the molecules studied.The relaxation times of the chain carbons were analysed in terms of a correlation function describing multiple internal rotations about successive C-C bonds.The results (rotational diffusion constants) were used to discuss features of the chain mobility as a function of chain length and chain unsaturation.The assumptions involved in the quantitative treatment were examined and the values were compared with those of n-alkanes and lipid bilayers. - Keywords: 13C NMR spin-lattice relaxation times Rotational diffusion constants Rotational dynamics Overall and internal motions Hydrocarbon-chain esters of fluorene-3-carboxylic acid

Hydrogenation of Oleic Acid to 9-Octadecen-1-ol with Rhenium-Tin Catalyst

A new supported bimetallic catalyst, rhenium-tin, is able to reduce oleic acid to 9-octadecen-1-ol (cis and trans isomers) with appreciable yield under mild hydrogenation conditions.This paper reports investigations on the effects of catalyst preparation methods, types of support, catalyst raw materials, mole ratio of the metals, activation and reaction conditions on the activity and selectivity of the catalyst.Catalyst derived from the combination of ammonium perrhenate and stannic chloride on alumina gave the best performance, and the presence of tin in the catalyst is essential for the preservation of the olefinic bond of the oleic acid during hydrogenation.KEY WORDS: Hydrogenation, 9-octadecen-1-ol, oleic acid, rhenium-tin catalyst.

Reduction of Long Chain and Bulky Carboxylic Esters by Sodium Tetrahydroborate

Methyl esters of long chain fatty acids as well as esters with functional (OH) and/or bulky substituents in alpha position and in the OR moiety may be effectively reduced with an excess of sodium tetrahydroborate at moderate temperature in dioxane-water without catalysts.The reaction has been applied to the reduction of a pool of triglycerides of natural origin (virgin olive oil) in order to obtain a mixture of the acyl residues reduced to the corresponding alcohols without any structural or configurational modification.They, no matter which was the advancement of the reaction, seemed to reproduce quite well the overall acyl composition, as shown by GC-MS analysis: the feasibility of such quantitative analysis may be extended, in order to obtain confirmatory evidences on the component identifications and to perform specific separations, to the corresponding chlorides, hydrocarbons and trimethylsilylethers.
