Abstract
Suspension or solutions of cyanuric chloride in water are prepared at high mixing velocities and low temperatures with resulting low degree of hydrolysis by introducing liquid cyanuric chloride through a nozzle in the upper portion of the mixing apparatus in countercurrent flow to upwardly flowing water introduced from at least one lower nozzle above a breast shaped constriction in the lower, open portion of the apparatus. In this way the chamber walls are always covered with an unbroken layer of liquid. The process can be carried out at normal, reduced or elevated pressure. At reduced pressure by evaporation of the water there is simultaneously a cooling of the system.
Claims4
A process for the production of a suspension or solution of cyanuric chloride in water comprising spraying cyanuric chloride downwardly and outwardly at a temperature in its molten range from upper portion of a vertical tubular zone closed at the top thereof to contact and mix with said water which forms a liquid layer defining said tubular zone, constricting said layer in breast-shaped manner downwardly below the place of entry of the cyanuric chloride into the tubular zone to form a narrower discharge opening, discharging said water as a spray tangentially to said layer and directed slightly upwardly in the direction of the closed top above said constriction and below the point of introduction of the cyanuric chloride and thereby forming said liquid layer along the entire tubular zone to the point of introduction of the cyanuric chloride, whereby the thickness of said layer where it is formed in the breast-shaped constriction is greater than it is in the remainder of the tubular zone.
