    摘要： It has been now surprisingly discovered after extensive research that 2-halo-4,6-bisaryl-1,3,5-triazine can be prepared with unprecedented selectivity, efficiency, mild conditions, and in high yield by the reaction of cyanuric halide with aromatics in the presence of at least one Lewis acid and at least one reaction promoter. This reaction is also unprecedently general as a variety of aromatics can be used to produce a wide selection of 2-halo-4,6-bisaryl-1,3,5-triazines. The novel approach includes the use of the reaction promoters in combination with at least one Lewis acid under certain reaction conditions to promote the formation of 2-halo-4,6-bisaryl-1,3,5-triazine compounds from cyanuric halide. Preferably, the Lewis acids and reaction promoters are combined to form a complex. 2-Halo-4,6-bisaryl-1,3,5-triazines are key intermediates for making 2-(2-oxyaryl)-4,6-bisaryl-1,3,5-triazine class of UV absorbers.

    摘要： The creation of novel halloysite-based compositions is disclosed. In one embodiment, the hollow clay nanotubes of halloysite are loaded with nanoscale zerovalent iron particles. The resulting composition provides an effective manner of remediating chlorinated hydrocarbons. In another embodiment, the hollow clay nanotubes of halloysite are imbibed with dispersants such as DOSS and Tween 80 surfactants. The resulting composition stabilizes oil-in-water emulsions and subsequently releases the surfactants, thereby reducing interfacial tension significantly, which allows much smaller droplets to form and thus provides for more effective oil remediation.

    摘要： This invention relates generally to benzocycle-substituted pyrimidines and triazines and the use thereof to protect against degradation by environmental forces, inclusive of ultraviolet light, actinic radiation, oxidation, moisture, atmospheric pollutants and combinations thereof. The new class of benzocycle-substituted pyrimidines and triazines comprises a benzocycle attached to the triazine or pyrimidine ring, and preferably an additional aryl ring containing a hydroxyl group, either free or blocked to form a latent stabilizer, ortho- to the point of attachment to the triazine or pyrimidine ring. These materials may, under the appropriate circumstances, be bonded to formulations comprising coatings, polymers, resins, organic compounds and the like via reaction of the bondable functionality with the materials of the formulation. A method for stabilizing a material by incorporating such benzocycle-substituted pyrimidines and triazines is also disclosed.
