Abstract: A tundish veneer composition comprising about 45-80 percent by weight of MgO, about 1-7 percent by weight of a refractory clay filler, about 1-15 percent by weight of a refractory glass wool fiber, about 3-10 percent of aqueous colloidal silica binder, and optionally, up to about 15 percent by weight of graphite, a foaming agent, or a dispersing agent.

Abstract: A method for the electrostatic precipitation of dust particles entrained in a gas stream which comprises adding predetermined amounts of an alkanol amine phosphate into the particle-laden gas stream in a location preceding the precipitation apparatus where the gas is at a temperature not greater than 650.degree. F.

Abstract: A method for the stabilization of both water-in-oil emulsions and solutions of poly trimethylamino methylol acrylamide is disclosed. The process consists of adding to the water-in-oil emulsion or solution containing the polymer from 10-50 mole percent of orthophosphorus acid based on the weight of the polymer. Water-in-oil emulsions of polymer are then stabilized by heating the emulsion for a period of time to obtain a stabilized emulsion of a water-soluble quaternary salt of poly trimethylamino methylol acrylamide. Solutions of poly trimethylamino methylol acrylamide need not be heated and are stablized by the addition of the orthophosphorus acid and mixing.

Abstract: The addition of citric acid to large amounts of catalyst fines allows their incorporation into catalyst formulations without the loss of important physical properties.

Abstract: Phosphate and phosphite mono and diesters in small amounts function as antifoulant additives in ethylene cracking furnaces which are subjected to elevated temperatures from about 500.degree. - 1700.degree. F. These furnaces produce material that deposits and accumulates upon furnace surfaces including furnace coils and transfer line exchangers. The present antifoulant additives inhibit and suppress fouling and also help clean up previously fouled furnace surfaces.

Abstract: A composition and method for the control of corrosion and foam in acrylonitrile plants is disclosed. The composition generally consists of a polypropylene glycol, a glyoxalidine salt of a carboxylic acid and an ethylene glycol monoalkylether. The composition when fed into absorbers, strippers, and quench towers of acrylonitrile plants provides excellent corrosion inhibiting and anti-foam properties.

Abstract: A method for treating aqueous wastes containing at least 1% proteinaceous matter with at least 0.20% by weight of cationic water-soluble polyamines. Preferred polyamines include ethylene dichloride-ammonia, quaternary ethylene dichloride-ammonia and dimethylamine-epichlorohydrin-ammonia polymer.

Abstract: A method for preparing a hydrotreating catalyst having a controlled pore distribution is disclosed. The method requires adding to the alumina prior to forming from 0.1 to 15% by weight of a water soluble polycarboxylic acid having from 2 - 22 carbon atoms. The resulting formed alumina support after being calcined has a pore volume distribution such that most of the pore volume in pores greater than 200 A in diameter as measured by Mercury penetration porosimitry is substantially eliminated. The pore volume as measured by nitrogen adsorption in the range of between 100 A and 1200 A is reduced. The polycarboxylic acid may be added to the catalyst carrier prior to forming in different ways such as by dissolving the catalytically active metals with the water soluble polycarboxylic acid and then impregnating hydrothermally or by pore volume or by adding a water soluble polycarboxylic acid salt to the hydrous or xero gel after precipitation.

Abstract: 1-aminoalkane--1, 1-diphosphonic acids of the formula, ##STR1## may be produced in good yield by reacting a nitrile of the formula,R -- CH.sub.2 -- C .tbd. Nwith at least 2 moles of phosphorous acid in the presence of a high boiling hydrocarbon oil at a temperature ranging between 140.degree.-170.degree. C without a catalyst. In the above formula, R is hydrogen, alkyl, aryl, arylalkyl, substituted aryl, substituted alkyl, and substituted arylalkyl. These compounds show anti-corrosive activity.

Abstract: ClO.sub.2 and its water-soluble salts are catalysts for water-soluble bisulfites when these latter compounds are used as oxygen scavengers in aqueous systems.

Abstract: An improved method for cationizing starch which comprises reacting an aqueous slurry of starch under alkaline conditions with a water-soluble quaternary ammonium polymer in the presence of a small amount of a metal-free oxidizing agent.
