Abstract
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.
Claims12
A continuous process for producing a monoalkali metal cyanurate which comprises:
- (a) continuously feeding cyanuric acid and continuously feeding an aqueous solution of an alkali metal hydroxide to a first reactor,
- (b) continuously reacting said cyanuric acid and said aqueous solution of alkali metal hydroxide to produce a first slurry comprised of cyanuric acid and a monoalkali metal cyanurate,
- (c) continuously conveying a portion of said first slurry to a second reactor,
- (d) continuously admixing said portion of said first slurry to further react said cyanuric acid with alkali metal hydroxide to produce a second slurry comprised of said monoalkali metal cyanurate, and recovering said monoalkali metal cyanurate.
