Abstract: Disclosed is a continuous process for purifying contaminated waste water. First the water passes through an equalization zone including at least two separate compartments, in one of which the pH of the water is adjusted to a range of from about 6.5 to 9.5. The water flows through the separate compartments such that the concentration of contaminants in the water exiting the equalization zone will approach about constant concentration which changes only gradually even though influent contaminant concentration changes rapidly. Water in at least one compartment of the equalization zone is aerated so that the dissolved oxygen in the water is at least three parts of dissolved oxygen per million parts of water. Solids are skimmed from the surface of the water in the zone, and coagulant is added to the effluent water from the equalization zone so that colloidal particles in the water flocculate. The water from this equalization zone is then filtered to remove flocculated particles.

Abstract: Novel catalysts and processes are disclosed for producing highly crystalline polypropylene and highly crystalline copolymers of propylene with ethylene or propylene with other alpha-olefins. Such catalysts can reduce the amount of low-molecular-weight and, particularly, amorphous polymers formed without serious effect on the polymerization yield. These novel catalysts and processes involve improving an alkylaluminum compound-titanium chloride catalyst by using in combination small amounts of hydrogen sulfide and a sterically hindered, lower alkyl substituted, cyclic, tertiary amine, a sterically hindered, lower alkyl substituted, cyclic, amine oxide, or a trihydrocarbylphosphite. Such catalyst systems are useful in slurry polymerization, bulk polymerization and techniques in which polymerization is accomplished utilizing monomer substantially in the vapor phase.

Abstract: Phenols alkylated with high molecular weight ethylene-propylene-diene terpolymers are obtained in essentially quantitative yields and with no measurable fragmentation of terpolymer by reacting terpolymer with a large excess of phenol, in the presence of BF.sub.3 as catalyst, at alkylation temperatures of about 170.degree.-300.degree. F. The preferred terpolymers consist essentially of about 35-45 mole percent propylene, 65-55 mole percent ethylene, and about 1.0-2.5 mole percent of a 5-alkenyl-2-norbornene such as 5-ethylidene-2-norbornene. The novel terpolymer alkylated phenol compositions are useful as intermediates for the preparation of multifunctional addition agents for lubricating oils, for example addition agents having combined dispersant-viscosity index improving properties.

Abstract: High surface area silver olefin oxide catalysts with orderly distribution of pore size are prepared by pyrolysis of silver salts of di- and polycarboxylic acids or mixtures thereof to carbon-like polymers containing silver, followed by combustion of the carbonaceous material. The resulting unsupported or supported silver catalysts are useful for oxidations, cyclizations, isomerizations, and cracking. The carbon-like polymers containing silver, before combustion of the carbonaceous material, find utility as bactericides and catalysts. Extraction of the silver yields high surface area carbon adsorbents of predetermined structure.

Abstract: A catalytic composition is produced by reacting in an aqueous medium, vanadium and phosphorus compounds together with a hydrogen halide and removing liquid from the resulting reactants to form a solid which in an improved manner is heated at a temperature of about less than 470.degree. C. to effect liberation of water of hydration from the solid and thereafter contacting with a reducing material selected from the group of carbon monoxide, hydrogen and hydrogen sulfide at a temperature of from about 300.degree. to about 600.degree. C. and in the substantial absence of gaseous oxygen other than that liberated from the solid. The specific reduction step as taught and claimed herein improves catalyst activity performance by increasing the catalyst conversion and selectivity to a desired oxygenated product, and the ultimate yield of the oxygenated product per quantity of feed component converted. It also minimizes formation of inactive VPO.sub.
