Abstract: PURPOSE:To prepare the title compound useful as a raw material of synthetic fibers and synthetic resins, etc., in high reaction rate and selectivity, by the catalytic reduction of the corresponding tetrahydroazepines with hydrogen in the presence of a specific catalyst and an additive. CONSTITUTION:1,11-Undecanediamine is prepared by the catalytic reduction with hydrogen, using 7-(5'-aminopentyl)-3,4,5,6-tetrahydro-2H-azepine of formula I as a starting material, in the presence of at least equimolar amount, based on said starting material, of water and excess amount of hydrogen chloride, using a catalyst containing iridium. The compound of formula I is obtained by the pyrolysis of epsilon- caprolactam or its polymer in the presence of a base, and is in equilibrium with the compound of formula II in the presence of water.

Abstract: PURPOSE:To produce the titled low-toxicity, irritating odor-free resin capable of forming a high-solid coating and a paint film of excellent appearance, by reacting a polyol with a specified triisocyanate compound. CONSTITUTION:A polyurethane resin is produced by reacting a polyol (e.g., trimethylolpropane, glycerin, or polypropylene glycol) with 1,6,11-undecane triisocyanate. This resin has properties inherent in a polyurethane resin, such as excellent adhesion to substrates, excellent balance between hardness and flexibility, cracking resistance, water resistance, chemical resistance, gloss, etc. In addition, the triisocyanate compound used has a low vapor pressure and emits no highly toxic volatile component. This composition can form a film excellent in appearance, heat resistance, and water resistance and form a high-solid coating because of its low viscosity, so that it can be designed as a nonpolluting coating.
