Abstract

4-ethylphenol and benzyl alcohol, the main depolymerization products of lignin, were used as reaction substrates to prepare high-density jet fuel precursor in an alkylation catalytic system coupled by acetic acid-choline chloride （Aa-ChCl） deep eutectic solvent and Amberlyst-15 ion exchange resin. The effects of reaction temperature, reaction time, molar ratio of the deep eutectic solvent components, catalyst amount and substrate molar ratio on alkylation were investigated. The results showed that a high conversion rates of benzyl alcohol （94.89%） and 4-ethylphenol （80.78%） were achieved at 170 ℃ over 4 hours with a molar ratio of benzyl alcohol to 4-ethylphenol of 1∶1 in an optimized system （Aa-ChCl at a molar ratio of 1：6 and an addition of 5% Amberlyst-15）. Meanwhile, the total selectivity and yield of 4-α-cinnamophenol （C_15-1） and o-isopropylphenol （C_15-2） could reach 74.58% and 60.24%, respectively.
