Abstract: A benzylalcohol derivative of the formula: ##STR1## wherein R is hydroxy, benzyloxy, halogen or alkoxy having one to four carbon atoms, and Ring A is monomethoxyphenyl, dimethoxyphenyl, trimethoxyphenyl or 3,4-methylenedioxyphenyl, or a pharmaceutically acceptable acid addition salt thereof is prepared by reducing a compound of the formula: ##STR2## wherein R' is benzyloxy, halogen or alkoxy having one to four carbon atoms, and Ring A is the same as defined above, to give a compound of the formula: ##STR3## wherein R' and Ring A are the same as defined above, and when R' is benzyloxy, if required, further subjecting the compound [I'] to catalytic hydrogenation to give a compound of the formula: ##STR4## wherein Ring A is the same as defined above. The benzylalcohol derivative [I] is useful as an anti-diabetic agent.

Abstract: This invention relates to a process for reducing amidine formation during reduction of organonitriles. The process comprises including a boron compound in the reaction medium in sufficient amount to complex the amidine compound as it is formed.

Abstract: Supported coprecipitated catalysts comprised of one or more metals of Group VIII, one or more metals of Group IIA, and aluminum are used for hydrogenating hydrogenatable organic compounds. The catalysts are produced by preparing, under agitation; an aqueous mixture containing ions of Group VIII, Group IIA, and aluminum, as well as solid porous particles to form a coprecipitate of the metal ions and aluminum ions with the solid porous support particles; heating the aqueous reaction mixture; and adding precipitating agent to precipitate the metal ions and aluminum ions onto the solid support.

Abstract: Unsaturated dinitriles are reacted with an aromatic compound such as benzene in the presence of a Lewis acid such as aluminum chloride to yield novel aralkylenedinitriles, such as 5-methyl-5-phenylnonanedinitrile and isomers thereof. The aralkylenedinitriles can be reduced to novel aralkylenediamines or novel cycloalkylalkylenediamines. Polymerization of the aralkylenediamines or cycloalkylalkylenediamines with polycarboxylic acids provides novel polyamides of tough, clear, colorless character.

Abstract: A process for prolonging the activity of catalysts during the hydrogenation of unsaturated dinitriles comprising pretreating the dinitrile feed with a crystalline zeolite.

Abstract: Heavy reaction product after separation as by distillation of light reaction product or diadduct from a reaction mixture obtained by reaction of olefinically unsaturated nitriles with monoolefinic hydrocarbons containing an allylic hydrogen atom is hydrogenated to produce a polyamine mixture useful as an epoxy resin hardener yielding cured resins exhibiting low water absorption.

Abstract: Supported coprecipitated non-ferrous Group VIII metal aluminum catalysts are used for hydrogenating hydrogenatable organic compounds. The catalysts are produced by preparing an aqueous mixture containing the metal ions, aluminum ions and solid porous support particles under agitation to form a coprecipitate of the metal ions and aluminum ions with the solid porous support particles; heating the aqueous reaction mixture; and adding precipitating agent to further precipitate the metal ions and aluminum ions onto the solid support.
