摘要： A continuous integrated process for the production of calcium hypochlorite in which crystals of by-product sodium chloride are more easily separated for the calcium hypochlorite product is described. The process includes: (a) introducing with agitation into a vessel an aqueous slurry of dibasic calcium hypochlorite, sodium hydroxide, and aqueous salt solution saturated with calcium ion and sodium chloride in amounts at least sufficient to substantially dilute the sodium hydroxide; (b) forwarding the resulting aqueous mixture of step (a) to a chlorination zone containing a seed bed of calcium hypochlorite and sodium chloride crystals; (c) introducing chlorine into the chlorination zone, thereby producing an aqueous suspension containing further quantities of calcium hypochlorite crystals and readily separable significantly larger sodium chloride crystals; and (d) removing aqueous suspension containing such calcium hypochlorite and sodium chloride crystals from the chlorination zone to a classification zone. Calcium hypochlorite crystals are maintained in suspension in and removed from the upper portion of the classification zone; while the larger and more dense crystals of sodium chloride settle and are removed from the lower portion of said classification zone.

摘要： A continuous integrated process for the production of neutral calcium hypochlorite in which crystals of by-product sodium chloride are more easily separated from the calcium hypochlorite product is described. The process includes diluting an aqueous slurry of sodium hydroxide, lime and bleach mother liquor with aqueous salt solution saturated with calcium ion and sodium chloride and chlorinating the resulting aqueous admixture in the presence of a seed bed of sodium chloride crystals and calcium hypochlorite crystals at temperatures less than 35.degree. C., e.g., 15.degree.-20.degree. C. A suspension of readily separable, sodium chloride crystals and calcium hypochlorite crystals in chlorinator liquor is conveyed to a classification zone where the sodium chloride and calcium hypochlorite crystals are separated.

摘要： A process for incorporating by thermal diffusion a photochromic substance into a synthetic organic host material is described. In the process, a surface of the host material containing a coating of a resin composition of from about 5 to about 50 parts of hydroxy (C.sub.2 -C.sub.3) alkyl cellulose, e.g., hydroxy propyl cellulose, and from about 95 to about 50 parts of poly(vinylpyrrolidone), which resin composition contains a photochromic substance, is heated to diffuse at least a portion of the photochromic substance into the surface of the host material. Subsequently, the coating is removed by washing with warm soapy water. In a particular embodiment, the host material is a polymer prepared from diethylene glycol bis(allyl carbonate).

The method described comprises depositing a thin uniform substantially dry film of a photochromic-bearing polymeric resin onto at least one planar surface of the synthetic plastic material, heating the plastic article and resin film substantially uniformly at temperatures near to but below the melting temperature of the photochromic substance for a time sufficient to transfer a photochromic amount of the photochromic material into the subsurface region of the plastic article, and thereafter removing the photochromic-lean resin film from the planar surface(s) of the plastic article.
