    摘要: A method for decomposing halogenated organic compounds which comprises: (a) preheating the halogenated organic compound to a temperature above about 300.degree. C. and (b) contacting the preheated organic compound with a platinum catalyst in the presence of an oxidizing agent at a temperature of at least 350.degree. C. The process converts the major part of the halide in the organic halide to hydrogen halide.

    摘要: Color may be removed from colored polyphenylated alkane by contacting this material with certain adsorbants. The adsorbants provided comprise certain crystalline zeolites in a silica alumina matrix and bauxite clay having at least one material selected from the group consisting of ferric oxide, titanium oxide, and zirconium oxide, which is activated by sulfuric acid and then calcined to provide the effective adsorbant.

    摘要: An improvement in the process for removing vinyl chloride from a water-polyvinyl chloride slurry, which contains unreacted vinyl chloride, by steam distillation is disclosed. In many instances, steam distillation of the slurry results in an increase in the number of gels or fish eyes. The improvement comprises conducting the steam distillation in the presence of a minor, but effective, amount of an alkali metal sulfite or carbonate. The improved process results in a polyvinyl chloride having no substantial increase in, or a reduced amount of, gels or fish eyes, while still having good heat stability and porosity properties.

    摘要: An improved method of preparing an aldehyde by passing alcohol and air through a reactor containing a silver catalyst is disclosed. Briefly, the improvment comprises passing the alcohol and air through a zone, packed with silver catalyst, maintained at subreaction temperature prior to passing the reactants through the reaction zone. In a preferred embodiment, the reactants, after leaving the reaction zone, are passed through a zone containing inert material and maintained at a subreaction temperature.
