  • Patent number: 10752549
    Abstract: The present invention relates to modification of hydratable cement and cementitious materials, such as mortar cement and masonry or ready-mix concrete using ketone alcohol oil waste (“KAOW”) material, obtained as an alkali-soluble liquor waste byproduct at a certain stage in the commercial production of cyclohexanol and cyclohexanone. Preferred applications for KAOW are in chemical admixture formulations whereby KAOW is used to substitute for a portion of a cement dispersant such as sodium lignosulfonate, sodium gluconate, or other conventional dispersant. Another preferred use is in mortar cement and masonry concrete units such as blocks, pavers, curbstones, and other concrete masonry units wherein air void systems advantageously foster freeze-thaw durability.

The catalysts of the invention include gold (including gold sol-gel compounds) and sol-gel compounds containing particular combinations of Cr, Co, Zr, Ta, Si, Mg, Nb, Al and Ti, wherein certain of those metals have been combined with an oxide, such as an inorganic matrix of hydroxides or oxides, or combinations thereof. The catalysts may also optionally be supported on a suitable support member.

  • Patent number: 6002026
    Abstract: The present invention relates to novel oxidative processes for substrates such as olefins, alkanes, aromatics and alcohols using metallic porphyrin or salen catalytic complexes which have been specifically designed to maximize catalytic activity, thereby enhancing efficiency, selectively and speed of oxidation of these substrates. The choice of the substituents in the metallic complexes may be varied, but must be chosen to prevent specific ligand set arrangements known to be stable and therefore less catalytically efficient. Coordination complexes, particularly porphyrins and salens having nitrosyl axial ligands and electron-withdrawing peripheral substituents are preferred. Ruthenium coordination metals are the preferred metal center, with the highly reactive catalytic species found to be Ru.sup.III.
