Abstract:
1. A process for separating a reaction product and an imide compound having an imide unit represented by the following formula (1): wherein X represents an oxygen atom, a hydroxyl group, or an acyloxy group, from a reaction mixture obtained by a reaction of a substrate selected from the group consisting of a hydrocarbon, an alcohol corresponding to the hydrocarbon, an aldehyde corresponding to the hydrocarbon, a ketone corresponding to the hydrocarbon, an amine, a heterocyclic compound, a thiol, a sulfide, and an amide, in the presence of the imide compound, wherein the reaction mixture is obtained by (i) oxidizing the substrate with oxygen, (ii) carboxylating the substrate with oxygen and carbon monoxide, (iii) nitrating the substrate with a nitrogen oxide, (iv) sulfonating the substrate with a sulfur oxide, (v) acylating the substrate with a vicinal-dicarbonyl compound, or (vi) radically coupling the substrate with a compound which is radically formable of a carbon-carbon bond, which process comprises separating said reaction product and said imide compound from said reaction mixture by solvent-crystallizing the imide compound from said reaction mixture with water or a mixture of water and at least one solvent selected from the group consisting of a hydrocarbon and a chain ether, or, when the reaction mixture is obtained by an oxidation reaction of a monocyclic C
