    摘要: A method for purification of acetone containing at least one oxidizable impurity. The method comprises the steps of: (a) contacting acetone containing at least one oxidizable impurity with a heterogeneous oxidation catalyst in the presence of oxygen for a time and at a temperature sufficient to oxidize at least a portion of at least one of the oxidizable impurities; and (b) substantially separating purified acetone from the resulting mixture obtained from step (a).

    摘要: The presence of a base in the reaction mixture in a metal-ligand catalyzed partial oxidation of alkanes results in sustained catalyst activity, and in greater percent conversion as compared with oxidation in the absence of base, while maintaining satisfactory selectivity for the desired oxidation, for example the oxidation of isobutane to isobutanol.

    摘要: Significant amounts of soluble fluoride, known to create problems in processes requiring high quality grade calcium chloride, are removed from calcium chloride solution using hydroxyapatite as a removal mechanism. Under acidic conditions, calcium chloride solution is purified to about less than 10 ppm fluoride, significantly, to less than 1 ppm fluoride. At least 0.1 weight percent hydroxyapatite and concentrated hydrochloric acid are added to calcium chloride solution and slurried to remove fluoride and create a highly purified calcium chloride solution, substantially free of fluoride.
