RESULTS Six compounds were isolated and identified as ethyl palmitate (Ⅰ), myristie acid (Ⅱ), palmic acid (Ⅲ), β-sitosterol(Ⅳ), stigmasterol (Ⅴ) and campesterol (Ⅵ)re spectiuely.
结果 分离得到6个化合物,分别为棕榈酸乙酯(Ⅰ),肉豆蔻酸(Ⅱ),棕榈酸(Ⅲ),β-谷甾醇(Ⅳ),豆甾醇(Ⅴ),菜油甾醇(Ⅵ)。
In this experiment, we use ascorbic acid and palmitate ethylester as reactant, H2SO4 as catalyst to synthesis L-ascorbic palmitate by ester exchange method.
以L-抗坏血酸和棕榈酸乙酯为原料、H2SO4为催化剂,酯交换法合成L-抗坏血酸棕榈酸酯。
The influence on yield by the molar ratio of ascorbic acid to palmitate ethylester, consistence of catalyst, reaction temperature , reaction time, et al.
以L-抗坏血酸和棕榈酸乙酯为原料,H2SO4为催化剂,酯交换法合成L-抗坏血酸棕榈酸酯。
