Abstract: Dialkyl ethers present potential additives to motor fuels. The study considers the possibility of obtaining oxygenates from light pyrolysis resin. The interaction of 75–90 °C fraction from light pyrolysis resin (LPR), having high content of high molecular weight unsaturated hydrocarbons, compared to other lighter fractions of LPR with a significant content of saturated hydrocarbons, and ethanol at different reagent ratios in the presence of a catalyst, Purolite CT-151 ion-exchange resin (sulfonated copolymer of styrene and divinylbenzene) modified with Na+, K+, Cu2+, Ca2+, Co2+, Ni2+ ions, is analyzed. The iodine value is chosen as the key parameter reflecting the content of unsaturated structures. The greatest decrease in the iodine value is observed for the ion exchange resin modified with cobalt ions, which is further used as the etherification catalyst. At 75–90 °C fraction:ethanol ratio of 0.5:1.5 and 60 °C, the yield of oxygenates reached 4.9% by weight.
