Synthesis method of crude carboxylic ester (by machine translation)
-
Paragraph 0021; 0022, (2020/08/09)
The method is characterized in that the carboxylic ester and the ether are prepared by reacting a carboxylic ester with an ether at a certain temperature under the catalysis of a catalyst at a certain pressure for a certain time. (by machine translation)
Green preparing orthoformate cleaning process
-
Paragraph 0054; 0056; 0057, (2016/10/07)
The invention provides a green process for preparing orthoformate. A hydrogen chloride alcohol solution is prepared from a byproduct hydrogen chloride tail gas of the chlorine-related synthesis industry and then is slowly added into a reaction system, so that loss caused by escape of hydrocyanic acid is reduced, the yield is increased, great equipment corrosion caused by the byproduct hydrochloric acid prepared by the companies is avoided, the economic additional value of the byproduct hydrogen chloride is greatly increased, three wastes are avoided, the byproduct only comprises ammonium chloride, resources are reasonably utilized, and the green process for preparing the orthoformate is an environment-friendly production process and has a good social benefit.

In this article, the photocatalytic reaction of aniline and 4-amino N,N-dimethyl aniline with methanol, ethanol and isopropanol on anatase TiO 2 nano-particles under UV (365-nm wavelength) irradiation was examined. The concentration of unreacted arylamines and products was measured by gas chromatography picks integration, and then the products were identified by mass spectroscopy analysis. By making a comparison within the rates of photocatalysis of each arylamine in different alcohols under various irradiation times, it was revealed that, in all cases, the sequence of photocatalysis rate was methanol > ethanol > isopropanol. In reactions where the concentrations of arylamine were lower than 10 mmol/l, imines were the main products and the alkylation of amines was not observed. In the higher concentration of arylamines, oxidation and dimerization was occurred. Springer Science+Business Media B.V. 2010.
