n.氨解作用
The RNA was extracted from beer yeast by ammonolysis. 以啤酒酵母为原料,通过氨解法进行RNA提取的研究。
DL aspartic acid was produced by ammonolysis of maleic anhydride in a titanium autoclave. 在一钛材高压釜中,对顺丁烯二酸酐(马来酸酐)进行氨化反应合成了DL天冬氨酸。
In addition, the effect of concentration of acyl chloride on the rate of ammonolysis was very small. 但在反应后期，反应速率呈明显的二级反应特征。
Ammonolysis of dimethyl carbonate(DMC) to carbamate,a more promising route for synthesis of carbamate,was reviewed in detail,especially the catalysts. 认为碳酸酯胺解法是一种较有前途的方法,碳酸二甲酯胺解合成氨基甲酸酯是更具有工业应用前景的合成路线。
Methods: The preparation of levetiracetam is adopting Late Ring-closure route, which can optimize the condition of the compound ammonolysis process. 方法:采用后闭环路线,优化氨解反应的工艺条件。
