醋酸甲酯水解产物为甲醇-水-醋酸甲酯-醋酸,用气相色谱法分析此体系存在着甲醇、水不易分离,甲醇、醋酸甲酯、醋酸拖尾严重的现象.通过大量的实验和分析,提出以不对称因子τ作为固定相的选择依据.以癸二酸:硅油:GDX102=8:7:85为固定相的色谱柱已成功地应用在醋酸甲酯水解动力学研究中.
醋痠甲酯水解產物為甲醇-水-醋痠甲酯-醋痠,用氣相色譜法分析此體繫存在著甲醇、水不易分離,甲醇、醋痠甲酯、醋痠拖尾嚴重的現象.通過大量的實驗和分析,提齣以不對稱因子τ作為固定相的選擇依據.以癸二痠:硅油:GDX102=8:7:85為固定相的色譜柱已成功地應用在醋痠甲酯水解動力學研究中.

There are some difficulties in the analysis of ethanol-water-methyl acetate-acetic acid by gas chromatography. Firstly, methanol is hard to be separated from water. Secondly, the peaks of methanol,methyl acetate and acetate acidare lagged behind. Through lots of experiments, proper chromatography columnis made and used satisfactorily in the analysis of the methanol-water-methyl acetate-acetic acid.
