与ethanal相关的网络例句 [注：此内容来源于网络，仅供参考]

A spectrophotometric simultaneous determination of glutaraldehyde and ethanal based on the reaction between gluaradehyde or ethanal and thiobarbituric acid in acetic acid solution is described.

在醋酸介质中，硫代巴比妥酸与戊二醛及乙醛分别可生成2∶1及1∶1的缩合产物，这两种缩合产物在可见光区具有不同波长的最大吸收，籍此可同时测定戊二醛及乙醛。

To improve the selectivity, the Co/Mn/Br catalyst system with ethanal as an additive was studied and the reaction conditions were also optimized, which were as follows:the amount of ethanal 10%(mole ration base on the substrate), reaction temperature 100℃,reaction time 30min,the oxygen pressure 0.2MPa, the amount of the composite catalyst Co/Mn/Br 7%,the mass ration of different ingredients 2:2:1. Under these conditions, the yield comes to 24.10% and the selectivity reaches 75.03%.

为了提高反应的选择性，论文初步研究了以乙醛作为添加剂条件下各工艺参数的影响，并进行正交优化，得出最佳条件为：乙醛加入量1：10，反应温度100℃，反应时间30min，氧气压力0.2MPa， Co/Mn/Br混合催化剂加入量7%，质量比2：2：1，在此条件下，反应产率为24.10%，选择性可达75.03%。

Simple examples of aldehydes are methanal and ethanal (acetaldehyde, CH3CHO).

简单的醛有甲醛和乙醛（ CH3CHO ）。
