摘要： A process for drying a wet cake of aminoguanidine bicarbonate (AGB), which comprises subjecting the wet cake of aminoguanidine bicarbonate to drying temperatures from about 35.degree. C. to about 95.degree. C. under a carbon dioxide-containing atmosphere for a sufficient amount of time to form a dried aminoguanidine bicarbonate product which is substantially free of moisture.

摘要： Hydrated alkali metal dichloroisocyanurate particles are prepared in a process which comprises, in a first step, spraying droplets of an aqueous slurry of alkali metal dichloroisocyanurate into an evaporation zone fed with a moving stream of heated gas to evaporate water from the droplets and form dry porous solid spherical particles of hydrated sodium dichloroisocyanurate. In a second step, the dry particles are fluidized in a cooling gas until cooled to a temperature below about 50.degree. C. The resulting porous hydrated particles have a uniform distribution of hydration, are dust-free, and quickly dissolve in water.

摘要： A continuous process is disclosed for the production of monoalkali metal cyanurates. In the process, cyanuric acid and an aqueous solution of the alkali metal hydroxide are continuously reacted in a first reactor to produce a first slurry comprised of cyanuric acid and a monoalkali metal cyanurate. This first slurry is conveyed to a second reactor to further react the cyanuric acid with the alkali metal hydroxide to produce a second slurry comprised of the monalkali metal cyanurate.The novel process produces slurries of monoalkali metal cyanurate which are consistent both with respect to chemical composition and solids content while reducing equipment and operating costs.
摘要翻译：公开了用于生产单碱金属氰尿酸盐的连续方法。在此过程中，氰尿酸和碱金属氢氧化物的水溶液在第一反应器中连续反应，以产生由三聚氰酸和一碱金属氰脲酸盐组成的第一浆料。将该第一浆料输送到第二反应器以进一步使氰尿酸与碱金属氢氧化物反应，以产生由单碱金属氰尿酸盐构成的第二浆料。新工艺生产的单碱金属氰脲酸酯浆料在化学成分和固体含量方面均一致，同时降低了设备和操作成本。
