OBTAINING PROMISING OXYGEN-CONTAINING COMPONENTS OF MOTOR FUELS

Abstract

The paper presents the synthesis results of such promising oxygen-containing components of motor fuels as dibutyl ether and diethyl ether on the KU-2FPP sulfo-naphthionite catalyst and the LaH-USY zeolitecontaining catalyst. The chromatographic method of analysis investigated the effect of various process indicators on the composition of the esterification products, the yield of the target products, and optimal conditions were determined. It has been established that the optimal temperature of the esterification process and the bulk feed rate of the catalysts KU-2FPP and LaH-USY is 90 oС and 1 h -1 , respectively. The maximum yield of dibutyl ether with these parameters on the catalyst KU-2FPP was 10.24 % by weight. Under similar conditions on the sample zeolite-containing catalyst LaH-USY, the yield was 30.02 % of the mass. For the synthesis of dibutyl and diethyl ethers by the method of intermolecular dehydration, the zeolite-containing catalyst LaH-USY shows better catalytic properties than KU-2FPP and is more preferable from the point of view of possible application.
