A method of removing water from wet organoborane by dissolving the wet organoborane in an organic solvent in which water is incompletely soluble, decanting any insoluble water, and distilling the organic phase to remove water which may be contained therein.

Process for removing water from organoborane compounds

Process for separating alkenes, e.g., butene, from alkadienes, e.g., butadiene by preferentially hydrocyanating the diene and thereafter recovering the unreacted alkenes.

Separation of alkenes from alkadienes

Use of ammonia to control interfacial rag formation when olefin hydrocyanation products are contacted with a hydrocarbon.

Treatment of olefin hydrocyanation products

The process of oxidizing cyclohexane to produce cyclohexanone and cyclohexanol in the weight ratio of 0.5 to 1.5 of cyclohexanone to cyclohexanol, said process comprising contacting a stream of liquid cyclohexane with oxygen in each of at least three successive oxidation stages by introducing into each stage a mixture of gases comprising molecular oxygen and inert gas, said oxygen being introduced in amounts that may range from an amount that will substantially all react with the cyclohexane under the particular conditions involved to an amount in excess of the amount required to react with the cyclohexane, said excess being such that the overall oxygen consumed in the oxidation zone is not more than 95 mole percent of the amount fed under the particular conditions involved, in the presence of a binary catalyst system comprising 0.02 to 0.9 ppm chromium and 0.1 to 5 ppm cobalt at a temperature of from 130.degree. to 200.degree. C. and a pressure of from 60 to 350 psig, reacting any cyclohexylhydroperoxide that may be formed in the presence of said binary catalyst system and recovering a product of cyclohexanone and cyclohexanol in the above ratio.
