Abstract: Preparation of polyalcoholates involves the steps: (a) reaction of alcohols with bases with formation of an alcoholate containing mixture, (b) preparation of the mixture in a water-free form, (1c) feeding of the mixture into a rotary reactor, (d) feeding of alkylene oxide into the reactor in a number of sites, (e) reaction of the alcoholate and/or products of reaction. Preparation of polyalcoholates involves the steps: (a) reaction of alcohols with bases with formation of an alcoholate containing mixture; (b) preparation of the mixture in a water-free form; (c) feeding of the mixture into a rotary reactor; (d) feeding of alkylene oxide into the reactor in a number of sites; (e) reaction of the alcoholate and/or products of reaction between the alcoholate and alkylene oxide into the reactor. The steps (a) to (e) are continuous, the reactor is cooled externally, and the reactor is in the form of a plate-type heat exchanger, a plate-type heat exchanger system in a container with vapor cooling, a single way tube type heat exchanger, or a multi-way tube heat exchanger.
