active acetate

Compared with FFAP capillary Column, CP-WAX capillary column had better effects in the separation of several groups of substances such as ethyl acetate and acetal, active amyl alcohol and isoamyl alcohol.

与FFAP毛细柱相比，CP-WAX毛细柱能很好分离乙酸乙酯/乙缩醛、活性戊醇/异戊醇等几对难分离的物质。

Conclusion The fetid cassia seed ethyl acetate extract is the active situs of fetid cassia seed reducing blood lipid; its effective dose ranges 0.50~ 1.25 g · kg-1 · d-1.

结论决明子乙酸乙酯提取物为决明子降血脂的有效活性部位，其有效剂量范围在0.50～1.25g·kg-1·d-1之间。

Using silicotungstic acid as catalyst with the catalyst supported on active carbon, 2-methyl-2-ethyl-acetic-1,3-oxathiolane ( targeted compound I, an aroma compound with apple flavor) was synthesized by the reaction of ethyl aceto-acetate and 2-mercapto-ethanol.

以活性炭固载硅钨酸作为催化剂，用乙酰乙酸乙酯与巯基乙醇缩和合成了具有浓郁苹果香气的香料化合物2-甲基-2-乙酸乙酯基-1,3-氧硫杂环戊烷（Ⅰ）。
