    摘要： The present invention relates, in one aspect, to a process for preparing a storage-stable dispersion of a biocide which comprises the steps of: (a) mixing a plastisol, comprising a resin and a carrier, and a biocide to provide a mixture of said plastisol and said biocide (b) heating said mixture of plastisol and biocide to an elevated temperature of between about 30.degree. C. and about 100.degree. C. to provide a homogeneous, storage stable dispersion, said dispersion containing said biocide in an amount of between about one and about 30 weight percent based upon the weight of said dispersion, said resin being present in an amount of between about 5 and about 75 weight percent based upon the weight of said dispersion, with the proviso that when the weight percent of said resin in said dispersion is between about 30% and about 75%, then said elevated temperature is between 30.degree. C. and 45.degree. C., and when the weight percent of said resin in said dispersion is between about 5% and about 29%, then said elevated temperature is between 46.degree. C. and 100.degree. C., and (c) cooling the dispersion to a temperature of between about -20.degree. C. and about 40.degree. C. to provide a storage-stable mixture having a viscosity of between about 2,000 and about 30,000 centipoise.

    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.
