Abstract: A trans isomer of 4-cyanoncyclohexane-1-carboxylic acid or its lower alkyl ester is reduced in a solvent in the presence of a hydrogenating catalyst, and hydrolyzing the produced ester in case the starting trans-isomer is a lower alkyl ester, then the trans-4-aminomethyl-cyclohexane-1-carboxylic acid is recovered from the reaction mixture.

Abstract: Hydrocarbons are reacted with a silver tri-halogenomethane sulfonate of the formula ##EQU1## wherein X, Y and Z each represents a halogen atom, to form the corresponding complexes, and then the thus formed complexes are decomposed to selectively separate the desired hydrocarbon components. The used silver tri-halogenomethane sulfonate also is recovered by the decomposition of the complexes.

Abstract: Two component parts of thermoplastic resin each being constructed with a deck board having integrally formed on one surface thereof a plurality of girders being disposed along opposite edge portions at each corner thereon and therebetween and along a line parallel to and midway between the edge portions and a multiplicity of ribs of lesser projection therefrom than the girders are readily assembled by melt adhesion to form a pallet for a fork lift which exhibits excellent strength and rigidity to bending.

Abstract: A copper catalyst obtained by reducing a copper compound with formaldehyde in the presence of an alkali in an aqueous medium is an excellent catalyst for the hydrolysis of an unsaturated nitrile to an amide. Furthermore, when a copper compound is combined with another element, which is selected from a specific group of elements, during the preparation of the copper catalyst, a catalyst is formed which has an increased hydrolysis activity and an increased catalyst lifetime.

Abstract: A polymerizable diene polymer is prepared by reacting a polymerizable unsaturated carboxylic acid, anhydride, ester or acid halide with a polyhydroxydiene polymer having terminal and pendant hydroxy groups obtained from the reaction of one mole of a living polymer having a molecular weight of 500 to 10,000 which is prepared by reacting a conjugated diolefin or a mixture of said conjugated diolefin and a vinyl compound having the formula: CH.sub.2 = CR.sub.1 R.sub.2 wherein R.sub.1 represents a hydrogen atom or an alkyl group and R.sub.2 represents an aryl group or a pyridyl group in the presence of sodium or lithium metal or an organo sodium or lithium compound with 0.5 mole to 2.0 moles of epichlorohydrin, epibromohydrin, epifluorohydrin, chlorobutylene oxide or bromobutylene oxide.
