在高活性的非化学计量羟基磷灰石（HAP）催化剂上，植物来源的脱水乙醇在一步过程中有效地转化为乙酰胆碱。所述甲醇汽油的研究辛烷值为99，并且主要包含C6至C10的烃以及在使用沸石的甲醇至汽油（MTG）过程中不产生的含氧化合物。为了证实所提出的在HAP上由乙醇合成汽油的方案，使用五种不同醇与乙醇的成对组合进行醇转化。结果表明：（1）正构醇通过Guerbet反应得到正构醇和支链醇，（2）Lebedev反应得到二烯，（3）支链醇主要通过脱氢和脱水分别得到醛和烯烃。
Plant-derived, dehydrated ethanol was effectively converted to biogasoline in a one-step process on a highly active nonstoichiometric hydroxyapatite (HAP) catalyst. The biogasoline had a research octane number of 99 and comprised chiefly hydrocarbons from C6 to C10 as well as oxygenates not generated in the methanol-to-gasoline (MTG) process using zeolite. To confirm a proposed scheme for the synthesis of gasoline from ethanol over HAP, alcohol conversions were carried out using paired combinations of five different alcohols with ethanol. Results indicated that: (1) normal and branched alcohols were obtained by the Guerbet reaction from normal alcohols, (2) dienes were synthesized by the Lebedev reaction, and (3) aldehydes and olefins were mainly synthesized by dehydrogenation and dehydration of branched alcohols respectively.
