Abstract: PROBLEM TO BE SOLVED: To provide a method for purifying N-vinyl-ε-caprolactam for producing an N-vinyl-ε-caprolactam hardly manifesting any sensibility for color changes, i.e., having high color stability higher than that of usual N-vinyl-ε-caprolactam obtained by distillation.
SOLUTION: N-vinyl-ε-caprolactam to be purified having at least 95 mass % purity is changed to a molten liquid, which is partially crystallized and the crystal is separated from the mother liquid.

Abstract: PROBLEM TO BE SOLVED: To obtain an alkenyl compound stabilized in a color number having a remarkably low color number for expressing no tendency to be colored after a storage of longer period of several months or extremely slight coloration with avoiding an expensive cost. SOLUTION: The color number of an alkenyl compound having a divalent or a trivalent heteroatom at α position to a double bond is stabilized and/or lowered mixing an oxidizing agent with the alkenyl compound.

Abstract: PROBLEM TO BE SOLVED: To obtain the subject compound in a short time without generating a coupling product and effectively utilizing the starting substances by reacting a specific cyclopentene with formic acid in the presence of an acidic catalyst. SOLUTION: The objective cyclopentyl formate of the formula II is produced by reacting (A) 1mol of a cyclopentene compound of the formula I (R1 to R3 are each H or a 1-8C alkyl, preferably a 1-4C alkyl) with (B) 0.1-25mol of formic acid in the presence of (C) 0.0001-25mol of an acidic catalyst (e.g. a Lewis acid) at -80 to +200 deg.C, preferably 35-80 deg.C. The component A is available as a 5C stream from a cracking apparatus or an oil refinery plant. Cyclopentyl formate is useful as a production raw material for cyclopentanol.

Abstract: A process for the production of 1,6-hexanediol and 6-hydroxycaproic acid or their esters by catalytic hydrogenation of adipic acid, adipic acid monoesters or adipic acid diesters or of product streams that contain adipic acid or esters as essential components. The hydrogenated mixture is distilled to separate hexanediol, 6-hydroxycaproic acid and/or their esters and the bottoms product containing oligomeric esters of 6-hydroxycaproic acid is recycled to the hydrogenation step. The mixture to product and recycle stream is hydrogenated at 100-300 deg C and 10-300 bar in the liquid phase in the presence of a catalyst with a molar ratio of carboxyl groups to hydrogen of 1:5-1:100.
