摘要： The present invention relates to a process for preparing 2,6-dichloropyridine which comprises reacting an organic solvent-free, catalyst-free reaction mixture comprising 2-chloropyridine and chlorine in the presence of a hydrogen chloride scavenger and ultraviolet light, and optionally in the presence of added moisture, at a temperature of between about 90.degree. C. and about 185.degree. C. Also claimed is a method for preventing calcium chloride plugging of the chlorine feed stream and for preventing calcium chloride build-up in the above reaction mixture which comprises adding moisture in the form of water or steam, or a combination thereof, to the reaction mixture prior to, or during, the reaction of said process.

摘要： The present invention relates to a method for producing submicron-sized particles of pyrithione salts, comprising reacting pyrithione or a water-soluble salt of pyrithione and a water-soluble polyvalent metal salt in a pressurized turbulent flow reactor that generates pulverizing forces, the reaction producing submicron sized particles of pyrithione salt. The present invention also relates to particles made by the above method, and products, such as shampoos, soaps, and skin care medicaments made using these particles.

摘要： Disclosed is a composition and method for providing antimicrobial protection to plastic structures, such as plastic decking, planking, fencing, and panels. The method comprises applying a water-soluble biocide to the metal-containing structure, and converting the soluble biocide to a water-insoluble metal biocide salt that is adsorbed on the surface of, or into the porous structure of the plastic material. The slow release of the insoluble antimicrobial agent from the surface or from within the pores of said plastic structure provides antimicrobial protection for the plastic structure.
