Abstract: Laurolactam having high quality is produced by reacting cyclododecanone with a hydroxylamine salt of a mineral acid, and converting the resultant cyclododecanoneoxime to laurolactam through the Beckmann rearrangement reaction, wherein a content of each of oxygen atom-containing C12 organic compounds, for example, cyclododecenone or epoxycyclododecane, and cycloaliphatic unsaturated C12 hydrocarbon compounds, contained, as an impurity, in the staring cyclododecanone material, is controlled to 1,000 ppm or less.

Abstract: In reduction of an epoxy group-containing organic compound, for example, a C5-C20 saturated or unsaturated epoxy cycloaliphatic compound, in the presence of a nickel catalyst, by bringing the compound into contact with hydrogen, the target compound can be produced at a high yield by adding a basic substance (for example, an alkali metal hydroxide, an alkali metal carbonate, an alkali metal alkoxide, and an amine compound having 1 to 3 C1-C12 alkyl groups), to the reduction reaction system, to thereby restrict production of by-products due to a side deoxidation reaction.

Abstract: A curved surface screen-printing apparatus adapted to screen-print a to-be-printed object having a large radius of curvature. Concentric curved-surface guides having an equal radius of curvature are respectively provided on both side portions of a jig table on which a printing board to be bent and used as the to-be-printed object is placed. A squeegee head crossing over the jig table, and a screen plate mounting frame are provided in the apparatus. A pair of steel belts are used to connect a corresponding one of the guides to the frame. The belts of each pair are made to intersect each other. An end of each of the belts is fixed to a side end portion of a corresponding one of the curved surface guides as viewed from a side thereof. The other end thereof is fixed to a corner portion of the screen plate mounting frame. A reciprocating motion of the squeegee head causes the screen plate mounting frame to perform a rocking motion along the curved surface of the jig table.
