摘要： There is provided a tackifier composition especially suited for use with natural rubber latex and formed from an olefin resin, preferably a polymerized terpene hydrocarbon resin condensed with an unsaturated carboxylic acid or anhydride, optionally partially esterified with a C.sub.1 -C.sub.30 alcohol or phenol, and neutralized with a base, preferably a volatile base such as an amine, and then dispersed in an aqueous medium. The tackifier when added to a latex forms compositions useful particularly as pressure sensitive adhesives.

摘要： Improved conversions of primary allylic and benzylic alcohols are obtained in an Oppenauer oxidation process, under Oppenauer oxidation conditions, by carrying out the oxidation employing furfural as the hydrogen acceptor. Primary alcohols to which the present invention relates are allylic alcohols substituted in at least the 2-position with a hydrocarbon radical and benzylic alcohols.

摘要： Improved conversions of 3-substituted and 3,3-disubstituted allyl alcohols to the corresponding aldehydes are obtained in an Oppenauer oxidation process, under Oppenauer oxidation conditions, by carrying out the oxidation employing furfural as the hydrogen acceptor. The invention is particularly applicable to the oxidation of geraniol and nerol to citral, which can be converted directly to pseudoionone without purification.

摘要： In a process for the catalytic hydrogenation of unsaturated compounds, which process is characterizable as employing for the active catalyst a glyoxime complexed with cobalt and a base, referred to as a cobaloxime catalyst, the improvement for obtaining increased conversion and/or yield comprising employing a large excess of the glyoxime complexing agent in the hydrogenation reaction. The invention is particularly applicable to the selective reduction of certain .alpha.,.beta.-unsaturated aliphatic ketones and is described with reference to the highly selective hydrogenation of carvone to dihydrocarvone.
