The method of utilization of alcohol fraction containing mainly primary alcohols is proposed. The fraction is a waste product arising in the process of cyclohexanone manufacturing. Alcohols are converted into symmetrical and asymmetrical ketones. The reaction proceeds in a continuous manner in the gas phase at the temperature range of 330 - 450°C in a flow reactor with fixed bed containing Zr-Mg-Y-0 catalyst. After processing the initial fraction at the temperature of 420°C and with the load of lh exp -1, a ketone fraction containing mainly nonanone-5 (over 40%, which corresponds to 75% yield and 80% selectivity) was produced. Apart from nonanone-5 in the fraction were such ketones as heptanone-4, octanone-4, cyclohexanone and other; the total content of ketones in the obtained fraction was 58%.
