Abstract: Complexes are made by reacting a solid ammonium molybdate and a solid alkali metal molybdate with ethylene glycol. Stripping of water of reaction subsequent to complex formation is preferred. The ratio of moles of alkylene glycol to total gram atoms of molybdenum should be in the range from about 7:1 to about 20:1 and the ratio of gram atoms of molybdenum in the ammonium molybdate to gram atoms of molybenum in the alkali metal molybdenum should be in the range of about 1:1 to about 20:1. Solutions of the complexes are excellent catalysts for the reaction of propylene with an organic hydroperoxide such as tertiary butyl hydroperoxide to form proplyene oxide and tertiary butyl alcohol.

Abstract: Storage stable solutions of molybdenum/alkanol complexes in the alkanol are prepared by reacting a molybdenum oxide and ammonium hydroxide and an amount of a straight chain or branched chain C.sub.6 -C.sub.13 alkanol, within the range of about 10 to about 55 moles of alkanol per gram atom of molybdenum sufficient to form a storage stable molybdenum/alkanol complex. The complex-forming reaction is initiated in the presence of about 1 to about 4 moles of water per gram atom of molybdenum and about 0.5 to about 10 moles of ammonia per gram atom of molybdenum, the water and ammonia preferably being added in the form of concentrated ammonium hydroxide. The reaction is conducted at a temperature of about 120.degree. to about 190.degree. C. for a period of time, normally about 3 to about 8 hours, sufficient to substantially completely remove ammonia and water to provide a liquid reaction product comprising said solution of molybdenum/alkanol complex dissolved in unreacted alkanol and containing about 0.
