The purpose of this work was to identify the products of conversion of aliphatic alcohols (specifically, butyl alcohols) in the course of production of cobalt carbonyls in suspensions of cobalt carbonate, and also to study the dependence of the yield of these products on the conditions of the carbonylation reactions. It was found that variation of the CO//2:H//2 ratio (from 3:1 to 1:2. 3) has no significant influence on the yield of by-products of carbonyl formation, which was 0. 7-1. 2 mass % in all experiments. Increase of temperature (to 180 degree ) and of the reaction time (to 4-6 h) leads to some increase of the by-products yield (1. 2-1. 7 mass %), mainly owing to increase of the amount of water formed, and to some extent of the amount of isobutyraldehyde. However, it must be pointed out that the by-products obtained during carbonyl formation can subsequently be converted into the required compounds during use of alcoholic solutions of cobalt carbonyls in the course of hydroformylation of olefins. These products are undoubtedly aldehydes, formates, and acetals.
