METHOD FOR PREPARING LINEAR PRIMARY MONOALCOHOLS Russian patent published in 2007 - IPC C07C1/04 C07C29/16 C07C31/125 

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention relates to a method for synthesis of alcohol comprising synthesis of olefins by the Fischer-Tropsch process followed by the hydroformylation reaction and isolation of mixture of alcohols. Hydrocarbon fraction with the content of linear olefins 10-45 wt-% is separated from products reaction synthesized by the Fischer-Tropsch process with using cobalt catalyst by distillation followed by its hydroformylation with carbon monoxide and hydrogen taken in the molar ratio hydrogen to carbon monoxide = 1.0-5.0. The reaction of synthesis is carried out in the presence of cobalt-base catalyst and a substituted or unsubstituted monophosphocycloalkane ligand followed by steps of hydrogenation and distillation. Invention provides preparing a composition with the content of linear (C₇-C₁₂)-alcohols 60 wt.-%, not less, high rate of reaction and high selectivity of the process.

EFFECT: improved method of synthesis.
