摘要： A process for recovery of molybdenum from residual fractions derived from an epoxidation reaction of propylene with tertiary butyl hydroperoxide in liquid phase with tertiary butyl alcohol, in the presence of soluble molybdenum, which process comprises:Fractionating epoxidation reaction product for obtaining a liquid fraction containing essentially all molybdenum from the reaction product;Contacting the liquid fraction with anhydrous ammonia for forming a precipitate containing the major portion of the molybdenum and a liquid phase containing 500 ppm or less molybdenum;Separating the liquid phase from the precipitated solid;Evaporating the liquid phase under conditions of elevated temperatures and reduced pressure in the presence of 1 to 3% water for separation into an evaporator overhead vapor essentially free of molybdenum and an evaporator concentrate comprising essentially all of the molybdenum fed to the evaporator;Rapidly cooling evaporator concentrate from about evaporation temperature to about room temperature or less for converting the evaporator concentrate into a brittle, fracturable solid which is easier to accumulate and dispose of in an environmentally acceptable manner.

摘要： A process for the production of detergent range alcohols and ketones by reacting an alkane with a hydroperoxide in the presence of a transition metal porphyrin catalyst is described. Preferred hydroperoxides include cumene hydroperoxide and tertiary butyl hydroperoxide. The transition metal porphyrin catalyst may be transition metal phthalocyanines, transition metalloporphines and the like. The transition metal itself may be iron, manganese, cobalt and mixtures thereof. Suitable ligands include, but are not limited to imidazoles and lithium borate. Other useful additives include alkali metal perchlorates, such as sodium perchlorate, iodosylbenzene and alkali metal superoxides, such as potassium superoxide, and phase transfer catalysts such as tetrabutyl ammonium bromide.

摘要： An improved procedure for making molybdenum/ethylene glycol complexes useful as epoxidation catalysts wherein the cycle time necessary for catalyst preparation is significantly reduced by preparing a mixture of undiluted ethylene glycol with undiluted ammonium dimolybdate in the molar ratio of about 7 to about 20 moles of ethylene glycol per gram atom of molybdenum, heating the mixture from ambient conditions to a temperature of about 25.degree. to about 150.degree. C. over a 5 to 100 minute period while simultaneously reducing the pressure to about 5 to about 100 mm Hg and, after an appropriate holding time, if necessary, returning the mixture to ambient conditions and recovering an essentially solids free clear catalytically active solution of molybdenum/ethylene glycol complex in unreacted ethylene glycol having a molybdenum content of about 10 to 15 wt. % of molybednum.
