    摘要: A process is provided for the production of lactones by the catalytic dehydrogenation of aliphatic diols containing from 3-7 carbon atoms and optionally one or more ether linkages in the diol chain. The reaction is conducted in the liquid phase with a copper chromite catalyst at a temperature of from about 150.degree.-250.degree. C. in the absence of added hydrogen, and preferably at reaction conditions where yields are about 99%.

    摘要: Solid compositions comprising water degradable oligomers of hydroxyacetic acid and lactic acid having molecular weights of 800-4000 and containing 40-60 mole percent hydroxyacetic acid. The compositions are useful as controlled release agents for chemicals, especially as a toilet bowl cleaning component. Optional ingredients include dyes, fragrances, filler materials, surfactants, algicides, pest control agents, quaternary ammonium salts, and mixtures thereof.

    摘要: A process for chemical plating of nickel or cobalt onto materials otherwise noncatalytic to the plating baths by pretreating the materials with a reducing agent such as sodium borohydride or dimethylamine borane prior to chemical plating. Treating the material with an oxidizing agent prior to the pretreatment is also useful, especially for plating copper. The invention is particularly desirable for plating nickel onto copper conductor patterns on polymeric substrate circuit boards. The copper is plated with nickel, and the substrate is not.
