FIELD: industrial organic synthesis.
SUBSTANCE: polyetherpolyols are synthesized via reaction of diols or polyols with ethylene oxide, propylene oxide, butylene oxide, or mixtures thereof in presence of suspended multimetallic cyanide complex catalyst in reactor provided with stirrer, wherein reaction mixture is recycled with the aid of pump through externally located heat-exchanger.
EFFECT: increased productivity based on unit volume in unit at high quality of product.
