After analyzing the reaction mechanism through literature, we think the reaction from diethanolamine to iminodiatic salt is composed of two steps—reaction from alcohol to aldehyde and the disproportionation reaction of the aldehyde. The selectivity, conversion, rate of this reaction are mainly attributed to the capability of this catalyst.

通过查阅文献资料，分析了反应机理，认为二乙醇胺脱氢生成酸是由两步反应组成─醇脱氢生成醛与醛的歧化，催化剂的性能是影响反应转化率、选择性及反应速度的主要因素，确定了采用沉淀法制备Cu/ZrO2做催化剂。

This technology of puvifying polysaccharide of Polygonatum cirrhifolium root was investigated.

对卷叶黄精多糖的醇沉分离、脱蛋白和脱色素工艺进行了研究。

When both of them are present, the dispersion forms sterically stable state of strip structure.

TME表明，蒙脱土分散体系中加入 KCl使得蒙脱土颗粒聚集，而聚乙二醇导致经微絮凝；二者同时加入，体系形成细枝条状的空间稳定结构。

The removal of organic sulfur such as thiofuran , thioether and mercaptan is the main objective of dry desulfurization , and hydroconversion of organic sulfur and preventing the methanation side reaction are the technological difficulties of hydroconversion desulfurization. The combination of two-level conversion and two.1evel absorption is the preferential scheme for refined removal of high-concentration organic sulfur.

脱除噻吩、硫醚、硫醇类有机硫是干法脱硫的主要目标，加氢转化有机硫并防止发生甲烷化副反应是加氢转化脱硫的技术难点，组合式两级转化、两级吸收是精脱高浓度有机硫的优选方案。

The cell of Gardenia jasminoides Bills has priority to using glucose;(5) The capacity of GJEP production was decreased in later stage, one of the important reason was that the carbon source in the medium was used up;(6) Excessive nitrogen source was not good for producing GJEP;(7) Auxins have more affective on cell growth and polysaccharide production.

我们采用了正交实验设计确立了板子多糖的提取和Saveqe法除蛋白的耕，结果发现，用50倍体积的碱水在80℃下提取2小时，再经过一系列醇析、脱色和脱蛋白等处理，桅子果实多糖的得率为1.74％，是文献报道的3倍。

This article describes the present situation of high-pressure and low-pressure flash tank ,gas-liguid separator and purified gas filter.
