气相色谱法定量分析α－乙酰－γ－丁内酯

?Butyrolactone, α-acetyl-γ-butyrolactone and solvent in reaction mixtures from the preparation of α-acetyl-γ-butyrolactone were determined by gas chromatography.The analytes were separated at 190℃ on a 1m ×3mm stainless-steel column packed with silanized 102 white support coated with polydiethylene glycol succinate and monitored with a thermal conductivity detector. The relative error was less than 2.5%.
