Abstract: Mixtures of a curable phenolic resin and an organic diaziridine are strong adhesives curable in a relatively short time at moderate temperatures to make strong bonds with wood, metal, and plastics.

Abstract: Lanthanum phosphate, lanthanum pyrophosphate and rare earth phosphates and pyrophosphates containing a major portion of that lanthanum compound are good catalysts for oxydehydrogenating alkyl aromatic compounds, including nitrogen heterocyclics having at least one C.sub.2 -C.sub.6 alkyl side chain to form derivatives having side chain unsaturation. The alkyl aromatic compound can have 1-2 rings. The process is carried out at 450.degree.-640.degree.C. and a space velocity of 55-2500.

Abstract: A method for removing antimicrobials such as pentachlorophenol from waste water by liquid-liquid extraction with a water immiscible organic liquid in a packed column; recovering the antimicrobial from the organic phase by distillation if desired; and, treating of the aqueous phase to remove residual antimicrobial and organic liquid. The process of the present invention recovers about 99 percent of the antimicrobial pentachlorophenol in the waste water producing a waste water containing less than 30 ppm pentachlorophenol and less than about 2 percent organic liquid, both of which may be removed by conventional carbon absorption or soil percolation to acceptable ecological levels for introduction into a stream or reuse as process water.
