CaO催化柠檬醛一步合成脱氢柠檬醛的初步研究

摘要

By using cyclohexane as solvent and N2 gas as protective gas, citral (3,7-timethyl-2,6-diene-octanal-1) was able to be chemically converted into dehydrocitral (3,7-demethyl-2,4,6 -triene-octanal-1) over CaO at 60℃. The total yield of dehydrocitral could be optimized to 33.4 % while the selected mass ratio of CaO/citral was 2.%环己烷为溶剂，60℃和N2保护下．CaO可催化柠檬醛（3，7-二甲基-2，6=二烯-辛醛-1：1）脱氢生成柠檬醛（3，7-二甲基．2，4，6．三烯．辛醛-1：II）。当CaO／柠檬醛质量比为2时，目标产物脱氢柠檬醛得率33．4％。
