Abstract For sustainable production of chemicals like hydrocarbons and oxygenates from renewable carbon sources electricity Fischer‐Tropsch synthesis is focused in current research. Aiming for this purpose, the development supported powdered shaped catalysts low‐temperature value‐added higher alcohols was addressed study. Promising support materials α‐Al 2 O 3 , SiO ZrO SiC were assessed influe...

The studying of enzymatic esterification of carboxylic acids and higher alcohols was performed by esterase Saccharomyces cerevisiae in water-organic medium. Investigation of the enzyme specificity to acetic substrates showed the best result with acetic acid in esterification reactions with ethanol whereas within other carboxylic acids the esterification decreased with acids: hexanoic > pentanoi...

A highly regio- and stereoselective CuCl-mediated carbometallation reaction of 3-aryl-substituted secondary propargylic alcohols with alkyl, aryl, vinyl or allyl Grignard reagents for the synthesis of fully-substituted allylic alcohols was developed. The R(2) group from the Grignard reagent was successfully introduced to the 2-position of the propargylic alcohols due to the chelation of metal a...

Large quantities of C27 bile alcohols hydroxylated at C-25 are excreted in the bile and urine of patients with cerebrotendinous xanthomatosis, a lipid storage disease that results from defective bile acid synthesis. The presence of both biliary and urinary bile alcohols reflects impaired bile acid synthesis. After treatment of samples with beta-glucuronidase, plasma bile alcohols were quantitat...

Multiwalled carbon nanotubes (MWCNTs) were functionalized with salicylic acid (SA). The copper-cobalt catalyst was impregnated on the SA functionalized MWCNTs (SA-MWCNTs). The catalyst copper-cobalt/SA-MWCNTs was used to catalyze the synthesis of alcohols from synthesis gas. Salicylic acid can promote the synthesis of ethanol and butanol from synthesis gas, thus reducing the synthesis of methan...

Both bile acids and bile alcohols, a subclass of steroids, are made from cholesterol as its major end metabolites by the liver of vertebrates. Their conjugates are the major constituents of the bile and possess a special function as an aid to intestinal lipid digestion and absorption. The most common naturally occurring bile acids in mammals, birds, most snakes, and various teleostean fishes, a...

The enantioselective oxidation of secondary alcohols represents a valuable approach for the synthesis optically pure compounds. Flavoprotein oxidases can catalyse such selective transformations by merely using oxygen as electron acceptor. While many flavoprotein preferably act on primary alcohols, FAD-containing alcohol oxidase from Phanerochaete chrysosporium was found to be able perform kinet...
