    Abstract: Unique polyphase compositions are disclosed having, as a continuous phase a propylene polymer and as a second phase a substantially amorphous organic material selected from solid or semi-solid hydrocarbons and hydrocarbon resins. These compositions are prepared by dispersing a propylene polymer of substantially all sub-micron particle size in the second phase and fusing the polymer under controlled conditions which assure the formation of the propylene polymer into a continuous phase.

    Abstract: Oil is removed from contaminated water by means of a fibrous structure of low denier polyolefin fibers attached to a pumping system. The polyolefin fiber structure can absorb many times its own weight of oil while absorbing little or no water. The oil is then easily removed from the fibrous structure by pumping.

    Abstract: Process, integrated with ammonia air oxidation, for the manufacture of nitric oxide of at least 99 percent purity comprising the steps of (1) effecting the ammonia oxidation, (2) maintaining maximum NO content in the oxidation effluent, and then contacting the effluent with nitric acid to convert the NO to NO2, (3) cooling the NO2 containing gas product to condense the NO2 therefrom as liquid N2O4, (4) passing the liquid N2O4 into a packed converter tower and therein at least partially vaporizing the liquid; passing resulting vaporization product upwardly through the tower packing and passing water or weak nitric acid into the tower and downwardly through the packing in countercurrent flow reaction contact with the vaporization product, and then into the zone of said vaporization and reaction contact with any unvaporized liquid, and vaporization product to convert substantially all of the initially added liquid dinitrogen tetroxide to nitric oxide gas product containing minor contaminant amounts of NO2, HNO3 and water, (5) water-scrubbing the NO2 and HNO3 contaminants from the NO gas product to form resulting water-wet NO gas product containing, on an anhydrous basis, at least 99 percent NO, and (6) dehydrating the water-wet NO gas product to form said NO of at least 99 weight percent purity. Strong nitric acid is formed in the converter tower as by-product.
