摘要： Provided herein is a cyclic imide slurry composition and processes for forming and/or using such a composition. The slurry composition comprises solid cyclic imide and organic liquid, such as liquid alkylbenzene, liquid cyclohexane, and/or liquid organic alcohol (such as cyclohexanol). The slurry composition may find particular use in processes in which the cyclic imide serves as an oxidation catalyst (e.g., as a radical initiator). For instance, the slurry composition may be useful in the oxidation of a liquid alkylbenzene such as cyclohexylbenzene to corresponding 1-cyclohexyl-1-phenyl hydroperoxide. Such an oxidation reaction may further be part of an integrated process for the production of phenol and/or cyclohexanone from benzene via hydroalkylation to form cyclohexylbenzene.

摘要： Provided are purification methods, comprising: (a) providing an organic solvent and a phenolic peroxide formation inhibitor, wherein the organic solvent has a first boiling point at standard atmospheric pressure (bp1) and the phenolic peroxide formation inhibitor has a second boiling point at standard atmospheric pressure (bp2) that satisfy the following inequality (I): bp2≤(1.10)(bp1)   (I); and (b) heating the organic solvent and the phenolic peroxide formation inhibitor to a temperature causing the organic solvent and phenolic peroxide formation inhibitor to vaporize, and (ii) condensing the vaporized organic solvent and peroxide formation inhibitor to provide a purified mixture of the organic solvent and peroxide formation inhibitor. The methods find particular use in the purification of solvents that are useful in process chemicals for the manufacture of semiconductor devices.

摘要： A method and a system for inexpensively producing a corresponding target ketone and/or alcohol by decomposing hydroperoxide rapidly and with high selectivity using an aqueous alkaline solution and by recovering and recycling alkali. The method includes neutralizing at least a part of a carboxylic acid in the oxidation reaction solution by contacting the oxidation reaction solution with a first alkaline solution including a carbonate of an alkali metal, and separating the reaction mixture into a first oil phase and a first water phase; decomposing the hydroperoxide and the ester compound in the first oil phase by contacting the first oil phase with a second alkaline solution having a higher pH value than the first alkaline solution, and separating the reaction mixture into a second oil phase and a second water phase; and recovering the carbonate of an alkali metal from the first water phase and recycling the carbonate of an alkali metal to the first alkaline solution.
