Etiracetam was firstly synthesized from 2-pyrrolidone by N- alkylation reaction and aminolysis reaction in internal.

首次在国内以2-吡咯烷酮为起始原料经N-烷基化反应和氨解反应合成了乙拉西坦。

The aminolysis degree of macroinitiator can affect the stability of emulsion and the polymerization rate of monomer.

大分子引发剂在水中的胺解程度对乳液的稳定和聚合速率都有影响。

Methods: Two substituted cinnamamides were first prepared by the aminolysis reaction of substituted cinnamyl chloride and aliphatic amines in anhydrous benzene.

方法 :通过取代桂皮酰氯与脂肪胺发生氨解反应 ,合成了三个酰胺类化合物。

The aminolysis reaction temperature, time and concentration of PLA membranes were studied. The suitable aminolyzed condition of PLA membranes is 45℃, 4min, in 0.09g/ml ethylenediamine, or 60℃, 6min, in 0.09g/ml 1,6-hexanediamine.

通过研究温度、时间和浓度对PLA氨解的影响优化了胺解条件,乙二胺在45℃、4min、0.09g/ml,1,6-己二胺在60℃、6min、0.09g/ml的反应条件下较适合进行PLA的胺解,经过茯苓羧甲基多糖衍生物改性后的PLA,水接触角下降,亲水性提高。
