This invention provides processes for reducing the environmental availability of one or more environmental pollutants in solids, liquids, and combinations of solids and liquids.

Processes for reducing environmental availability of environmental pollutants

This invention provides zinc-free aqueous brine compositions. These zinc-free aqueous brine compositions have a density of about 14.3 pounds per gallon or more, and a true crystallization temperature of about 20&#xb0; F. or less, and comprise water and one or more inorganic bromide salts, with the provisos that

High density aqueous well fluids

This invention provides zinc-free aqueous brine compositions. These zinc-free aqueous brine compositions have a density of about 14.3 pounds per gallon to about 15.8 pounds per gallon, and a true crystallization temperature of about 20&#xb0; F. or less, and comprise water and two or more inorganic bromide salts, where the inorganic bromide salts include calcium bromide and cesium bromide. Processes for forming these zinc-free aqueous brine compositions are also provided.

These zinc-free aqueous brine compositions have a density of about 14.3 pounds per gallon or more, and a true crystallization temperature of about 20&#xb0; F. or less, and comprise water and one or more inorganic bromide salts, with the provisos that when calcium bromide is present, one or more other water-soluble inorganic salts are also present, when lithium bromide is present, calcium bromide is absent, when bismuth(III) bromide is present, one or more other water-soluble inorganic salts are also present, and for a true crystallization temperature of about 10&#xb0; F. or less, when manganese(II) bromide is present, one or more other water-soluble inorganic salts are also present. Processes for forming these zinc-free aqueous brine compositions are also provided.

Disclosed is a method for the preparation of easily-swallowed, reliably-dosed, aesthetically-improved tablets of sodium ibuprofen dihydrate, the method comprising the formation of the tablets with punches or presses comprising contact surfaces which are chrome or chrome-plated.

High content sodium ibuprofen granules, their preparation and their use in preparing non-effervescent solid dosage forms

Thermally-activated cellulosic-based carbon is rendered more thermally stable by exposure to a halogen and/or a halogen-containing compound. Such treated cellulosic-based carbon is suitable for use in mitigating the content of hazardous substances in flue gases, especially flue gases having a temperature within the range of from about 100&#xb0; C. to about 420&#xb0; C.

Self-ignition resistant thermally-activated carbon

Activated cellulosic-based carbon is rendered more thermally stable by exposure to water or aqueous acid, and optionally, to a halogen and/or a halogen-containing compound. Such treated cellulosic-based carbon has enhanced thermal properties and is suitable for use in mitigating the content of hazardous substances in flue gases, especially flue gases having a temperature within the range of from about 100&#xb0; C. to about 420&#xb0; C.

Brominated sorbents for removing mercury from emissions produced during fuel combustion

Described are granules composed at least of a substantial amount of ibuprofen, at least one pharmaceutically-acceptable super disintegrant, and at least one pharmaceutically-acceptable binder different from the super disintegrant(s), the super disintegrant(s) being substantially uniformly dispersed throughout the granules. The methods for preparing such granules are described. The granules are useful in forming solid dosage forms such as filled capsules or compressed solid dosage forms.

High ibuprofen content granules and their preparation and their use in pharmaceutical dosage forms

Mixtures of isomeric alkylthiated mononuclear aromatic amines comprising in the range of about 30 to about 70 mole percent of (i) at least one 3,5-di(alkyl-thio)-2,6-diamino-1-alkylbenzene and in the range of about 30 to about 70 mole percent of at least one 3,5-di(alkylthio)-2,4-diamino-1-alkylbenzene, such mixture containing at least about 90 mole percent of (i) and (ii), and optionally containing up to 10 mole percent of one or more isomers of (i) and/or (ii). An alkyl group may be present as a substituent in lieu of a hydrogen atom in the remaining ring position. These mixtures are useful as curatives or extenders in processes for making polyurethanes, polyurethane-ureas, and polyureas.

Aromatic amine curatives and their use

Existing coloration of a liquid ring-polyalkyl-substituted aromatic primary diamine is reduced by blending into such diamine a color-reducing amount of at least one dihydrocarbylhydroxylamine. Preferably, the resultant product is stored in a closed container under an inert atmosphere.

Reducing the coloration of aromatic diamines

Odor formation during storage of (hydrocarbylthio)aromatic amines due to formation and release of odoriferous sulfur-containing species such as dihydrocarbyldisulfides, is suppressed. To accomplish this, a small amount of N,N-dihydrocarbylhydroxylamine odor-inhibitor (e.g., N,N-diethylhydroxylamine) is blended with the (hydrocarbylthio)aromatic amine. This enables products such as a mixture of 3,5-di(methylthio)-2,4-diaminotoluene and 3,5-di(methylthio)-2,6-diaminotoluene) to be stored for long periods of time with significantly reduced formation and release of odoriferous sulfur-containing species.
