The disclosure describes the preparation and use of reactive carbonates containing a metal carbonate bound to a reactive compound, wherein the reactive compound comprises a mineral binding group and a polymer reactive group connected together by a linking group. Such reactive carbonates are useful as reagents in processes for making mineral-bound elastomeric materials, and in methods for reducing cavitation in elastomer materials.

Inorganic particulate compositions containing inorganic particles associated with a copolymer of a hydrophilic monomer and a hydrophobic monomer associated with the inorganic particles are provided. The particulate composition satisfies at least one of the following properties:

Inorganic material composition and utilities thereof

A method for using a composition for use as rock dust in an underground mine is disclosed. The composition includes a fine, wet ground inorganic particulate material treated with at least one hydrophobic treatment, and a coarse, untreated, dry ground inorganic particulate material. Also disclosed is a composition including coal dust and mine rock dust including a fine, wet ground inorganic particulate material treated with at least one hydrophobic treatment, and a coarse, untreated, dry ground inorganic particulate material. The amount of mine rock dust may be sufficient to render the coal dust explosively inert according to at least one of a 20-L explosibility test or an ASTM E1515 explosibility test. The fine, wet ground inorganic particulate material may be calcium carbonate. The coarse, untreated inorganic particulate material may be calcium carbonate. The fatty acid may be stearic acid.

Non-caking mine rock dust for use in underground coal mines

Compositions and methods of using rock dust are disclosed. A mine rock dust may be capable of being applied in a wet form. A moisture tolerant mine rock dust may include a hydrophobic inorganic particulate material. A moisture tolerant mine rock dust may be capable of being dispersed by a light blast of air. A method may include applying a mine rock dust at a concentration having little or no respirable mine rock dust. A method of applying a mine rock dust may include applying a mine rock dust in a wet form. The mine rock dust may be applied at a concentration having little or no respirable mine rock dust. The mine rock dust may include a hydrophobic inorganic particulate material.

Moisture tolerant rock dust and methods of application thereof

A process for treating a sulfurous fluid to form gypsum and magnesium carbonate, whereby the sulfurous fluid is scrubbed with a sequestrating agent to yield a scrubbed fluid, gypsum and magnesium sulfate. The flue gas desulfurized gypsum is isolated from the magnesium sulfate solution by filtration or centrifugation. The magnesium sulfate is reacted with a carbonate salt to produce a magnesium carbonate whereby the reaction conditions are controlled to control the properties of the magnesium carbonate produced.

Process for treating a sulfurous fluid to form gypsum and magnesium carbonate

The present disclosure relates to the preparation of acrylate, alkacrylate, allyl, and polycarbonate derivatives of hydroxy ketal esters, and uses thereof.

Ketal ester derivatives

A ketal ester of an oxocarboxylic acid and a process to make the same, where the ketal ester is of Structure (I): wherein a is 0 or an integer from 1 to 12; n is 0 or 1; Ris a linear alkyl, aryl, arylalkylene, or branched alkyl group with 1-18 carbon atoms; Rand Rcan be hydrogen, Cstraight chain or branched alkyl, phenyl, substituted phenyl, C1-6 alkyl substituted with up to four OH groups, C1-6 alkyl, or acetyl optionally substituted hydrocarbon radicals, or Rand Rtogether with the &#x3b1;-carbon form a cycloaliphatic or heterocyclic ring with 3-6 carbon atoms and 0-3 heteroatoms, provided that only one of Rand Ris hydrogen; Ris a linear alkyl or branched alkyl group with 1-18 carbon atoms; and Ris hydrogen, or an alkyl, aryl, aralkyl or branched alkyl group with 1-10 carbon atoms. 

Ketal esters of oxocarboxylic acids and process of making

Novel ketal compounds can be made from an oxocarboxylate and a triol. Novel polymeric structures are, in turn, synthesized from the ketal compounds. Such ketal compounds and associated polymers are useful in a broad range of applications as a substitute for materials derived from petroleum or other such nonrenewable resources.

Ketal compounds from polyols and oxocarboxylates

The invention relates to polyketal compounds. The compounds are synthesized by the selective ketalization of oxocarboxylic acids, e.g. keto acids and semialdehydes, and esters thereof with tetrols and higher polyols that products two or more cyclic ketal ester moieties per molecule, wherein the cyclic ketal moieties are situated in a bis-, tris-, or polyketal conformation. The invention further relates to applications of these compounds and subsequent reactions thereof.
