Abstract: An integrated process providing for a gas phase hydro-oxidation of an olefin, preferably, propylene, with oxygen in the presence of hydrogen and a catalyst under reaction conditions such as to form a gaseous hydro-oxidation effluent stream containing an olefin oxide product, preferably, propylene oxide, water, unconverted olefin, oxygen, and hydrogen; and further providing for separation and recovery of the olefin oxide product from the effluent stream. The separation involves feeding the hydro-oxidation effluent stream into a first distillation column employing a liquid reflux rectification agent to obtain a first overhead stream containing unconverted olefin, oxygen, and hydrogen, which is recycled to the hydro-oxidation reactor, and a first bottoms stream containing water and the olefin oxide, from which upon further separation a purified olefin oxide product is recovered.

Abstract: A process is provided for the recovery of hydrogen chloride in anhydrous form from a dry (containing less than about 500 parts per million by weight of water) mixture of hydrogen chloride with one or more non-condensable gases and which may also contain components heavier than hydrogen chloride, which process comprises distilling the mixture to produce an overheads stream containing the non-condensable gases and about 95 percent or more by weight of the hydrogen chloride in the mixture and a bottoms stream containing about 95 percent or greater by weight of all components heavier than hydrogen chloride, and compressing and refrigerating the overheads stream whereby a selected proportion of the hydrogen chloride in the overheads stream is produced in a liquid anhydrous form containing less than about 50 parts per million by weight of water.

Abstract: A saturation process for essentially completely saturating unsaturated halogenated hydrocarbonaceous materials in a feedstock containing such unsaturated materials, employing a first recycle reactor for accomplishing the bulk of the saturation and a second, single pass, plug flow-type polishing reactor in combination.
