摘要： Powder coating a substrate with a polyolefin or preferably a polyolefin-polycarbonamide blend before contacting the substrate with a plastic resin creating a plastic-substrate seal, inhibits liquid and vapor transmission through the seal. The application of this invention to battery terminal bushings prevents unsightly corrosion about the battery terminal which is caused by "wicking" of battery acid.

摘要： A method for preparing a catalyst having one or more noble metals disposed in a relatively homogeneous distribution on a base which includes an inorganic refractory binder and a zeolite. The method provides for uniformly depositing noble metals on the base after it is formed, without unnecessarily displacing desirable nonframework cations, such as sodium, from the zeolite.

摘要： This invention pertains to the production of high purity iso- or terephthalic acid by the catalytic liquid phase oxidation of m- or p-xylene with molecular oxygen gas in the presence of a solvent system consisting essentially of 85 to 97 weight percent liquid benzoic acid and 15 to 3 weight percent water to provide a fluid feed for the purification of such phthalic acid by hydrogenation of the fluid effluent of such oxidation in the presence of a heterogeneous catalyst containing a Group VIII noble metal at an elevated temperature at which all the aromatic oxygen-containing products are in solution under the requisite elevated pressure to maintain a liquid phase of said solution followed by the precipitation of such phthalic acid from solution and the separation washing and drying of the precipitate. Such integration of process steps eliminates expensive and time consuming intermediate steps of precipitating impure iso- or terephthalic acid from oxidation effluent, separation, washing and drying said impure precipitate as well as purification of solvent for recycle to oxidation.
