| titleOfInvention | A kind of method that oxygen catalytic oxidation lignite prepares carboxylic acid |
| abstract | The present invention relates to a kind of in aqueous solution using the method for molysite composite catalyst catalysis oxidation lignite preparation high yield carboxylic acid.This method is catalyst system using the mixture of soluble ferric iron salt and inorganic acid, and using oxygen as oxidant, selective oxidation lignite prepares the carboxylic acid of high yield in aqueous solution；Then the method for using organic extractant solution, product carboxylic acid is separated from the aqueous solution of catalyst system, and catalyst system water solution cycle utilizes.Compared with traditional alkali-dioxygen oxidation method, this method avoid the consumption of a large amount of inorganic bases, reduce the use of inorganic acid, and reduce the energy consumption in reaction process；With NaVO 3 The method that catalysis oxidation lignite produces carboxylic acid is compared, and soluble ferric iron salt is cheap, environmental-friendly. |
