The contacting produces an effluent comprising an oxidized hydrocarbon product and unreacted imide catalyst of said formula (I) and the effluent is treated with a solid sorbent to remove at least part of the unreacted imide catalyst and produce a treated effluent comprising said oxidized hydrocarbon product. The organic phase can then be recovered.

摘要： The invention relates to a method for producing diamine and carboxylic diacid salt. The invention also relates more particularly to a salt of this type in a non-dissolved state, and especially to the production of a solid hexamethylene diamine adipate salt. Said method consists of crystallizing the diamine salt from a solution with ultrasonic agitation. The resulting crystals have a more compact form and a smooth surface without significant visible floors.

摘要： This invention relates to methods of replacing water and cyclohexanone with acetic acid in an aqueous solution of catalyst, preferably a cobalt compound. Such an aqueous solution is produced by extracting catalyst with water from a cyclohexanone/water solution of reaction products made by the direct oxidation of cyclohexane to adipic acid. The replacement of both water and cyclohexanone are conducted in a solvent exchange column, wherein acetic acid dissolves the catalyst, while water vapors force the cyclohexanone into a condenser, followed by a decanter wherein two liquid phases may be formed and separated; an upper liquid phase containing a majority of cyclohexanone and a lower liquid phase containing a majority of water. The cyclohexanone may be removed in a pre-treatment zone, wherein also part of the water may be removed, before the concentrated catalyst extract enters the solvent exchange column.
