Abstract: A composition for regenerating weak acid cation exchange resin comprising about 70-80 weight percent alkali metal chloride, about 5-15 weight percent alkali metal carbonate, and the balance an alkali metal chelating polycarboxylate and a method of regeneration comprising contacting the resin with a solution of the composition are disclosed.

Abstract: Air revitalization compositions containing potassium superoxide which furr comprises from about 2 to about 10 weight percent of lithium monoxide, from about 0 to about 2 weight percent of silicon dioxide, and either from 5 to 10 weight percent of lithium metaborate or from 3 to 8 weight percent of calcium sulfate.

Abstract: A process for purifying a hydrogen sulfide containing gas, which comprises absorbing said hydrogen sulfide onto a mass comprising zinc oxide, alumina and a group II A metal oxide, a large proportion of the group II A metal oxide being in the form of aluminate or silicoaluminate; then regenerating the mass by passing an oxygen containing gas therethrough.

Abstract: A pourable solid filter material for the removal of foreign gases, particularly unpleasant odors, from the air comprises a granular composition. The granular composition is a mixture of at least one acid or basic chemosorptive substance which reacts chemically with the foreign gas, and a substance which stores moisture. A binder which binds the chemosorptive substance into the form of granules is preferably also used as the moisture storing substance. The granules may consist of spherical particles between 0.5 to 5 mm. in diameter. Suitable acid chemosorpents include organic carboxylic acids, amidosulphonic acid, p-toluene sulphonic acid, boric acid, sodium, potassium and ammonium hydrogen sulphates and phthalic andydride. Preferred basic chemosorbents include sodium and potassium carbonates, oxides or hydroxides of calcium and barium, sodium metasilicate, lithium carbonate, hydroxides of sodium or potassium, cement, and potash, double, and soda water glass.

Abstract: An aqueous solution of alkali metal hydroxides which is composed of:A. a 50% by weight aqueous solution of sodium hydroxide, andB. a 45% by weight aqueous solution of potassium hydroxide,With the weight ratio of A to B being 2:1.

Abstract: Soiled hot end coated glassware having a substantially colorless and transparent thin protective coating thereon including an organic coating material is washed in an inhibited aqueous caustic soda cleaning solution to inhibit the deleterious effects of repeated washings and thereby increase the effective life of the protective coating. The cleaning solution comprises on a weight basis from 0.3 to 6% of caustic soda, from 0.01% to 0.3% of at least one soluble zinc containing compound when calculated as zinc oxide, and the remainder water. Other ingredients which may be present include from 0.002 to 0.05% of a synthetic organic phosphate ester anionic surfactant having hydrotrophic properties, from 0.001 to 0.03% of a low foaming synthetic alkoxylated nonionic surfactant, and from 0.008 to 0.2% of a hard water conditioning sequesterant.

Abstract: A spill of a mineral acid is controlled and cleaned up by being absorbed into a granular composition containing ground marble chips, granular soda, granular magnesia and an appropriate normally solid pH indicator.

Abstract: A process for treating domestic, municipal or industrial liquid waste to reduce B.O.D. of the waste comprising adding a sufficient amount of an acid formula and a sufficient amount of an alkaline formula to said waste, to thereby cause evolution of heat and cause flocculation of solids, and separating the resulting solids from the liquid. The novel acid formula and alkaline formula are disclosed. Liquid wastes treated by the process of this invention can be safely discharged into rivers, lakes and streams. In addition the process is extremely efficient since flocculation is rapid, and in many instances starts immediately upon the addition of either formula to the liquid waste.

Abstract: Corrosion inhibition of ferrous metals by aqueous potassium carbonate solutions in acid gas treating systems is effected by a combination of antimony compounds with vanadium anions in the plus 5 valence state.

Abstract: A process for preparing a high solids paste dispersion of fine particle size solid material in a vehicle which comprises premixing the solid material with the vehicle and a deagglomerating agent. The proportions of solid material, vehicle and deagglomerating agent are such that the premix remains a dry discrete flowable powder. The premix is then passed through a colloid mill which converts the powder to a paste dispersion in the form of a coherent mass in one pass through the mill.
