ROTOR-STATOR-TYPE MIXING REACTOR FOR MIXING, AT LEAST, TWO FLUIDS, SUSPENSIONS OR SOLUTIONS AND METHOD OF ISOCYANATE PRODUCTION

摘要

FIELD: process engineering.SUBSTANCE: invention relates to mixing. Mixing reactor comprises rotary symmetric housing confined at front by face plate and including mixing chamber with separate inlets for, at least, two substances and one outlet. Note here that first substance inlet is made at mixing chamber shaft while second substance inlet is composed of multiple openings made in said face plate in symmetry about mixing chamber shaft. Note here that every opening is complemented with rod to be displaced along said shaft. Mixing reactor differs from known designs in that face plate has channels directed outward from first substance inlet in reactor shaft. Invention relates to production of isocyanate by phosgenation of primary amines whereat they are mixed with phosgene to react therewith in said reactor.EFFECT: higher quality and rate of mixing of substances with notable different viscosities.5 cl, 2 dwg, 1 tbl
