Zusammenfassung:FIELD: industrial organic synthesis and catalysts. ^ SUBSTANCE: invention relates to a method for processing of butanol-butyl formate fraction obtained in propylene hydroformylation process, which method comprises reduction of butanol-butyl formate fractions with hydrogen at 200-280°C, pressure 1-30 atm, and volumetric feedstock and hydrogen supply rate 0.1-0.5 and 50-500 h-1, respectively. Reaction is carried out on catalyst having following chemical analysis, wt %: copper oxide 48.0-63.0, zinc oxide 9.0-18.1, chromium oxide 19.0-34.8, graphite 1.0-5.1 and activity index below 40 to form butyl alcohols and carbon oxide as final products. Method allows using real non-diluted butanol-butyl formate fractions and achieving following results: conversion of butyl formates 94.5-99.5%, content of methanol and high-boiling products in hydrogenate 0.8-1.5 and 2.9-3.5%, respectively. ^ EFFECT: enhanced process efficiency. ^ 4 tbl, 2 ex
