Abstract: A process is described for purifying polyalkylene glycols obtained by adding alkylene oxide to alkylene glycol, in which, after addition is complete, the resultant polyalkylene glycol is treated at a pH of >7 with a bleaching agent selected from the group consisting of peroxides, peracids, percarbonates, perborates, peroxodisulfates or oxygen, in each case with or without addition of a bleaching activator. The process is suitable in particular for preparing polyethylene glycol having molar weights from 196 to 203 g/mol which meets requirements of pharmacopeias.

Abstract: A method for the purification of polyalkylene glycols (I) obtained by addition of alkylene oxides to alkylene glycols involves treating the crude product at pH above 7 with a bleaching agent selected from organic and inorganic peroxides, per-acids, percarbonates, perborates, persulfates and oxygen, in each case with the optional addition of a bleach activator. An independent claim is also included for pharmaceutically-active compounds, foods or food supplements containing (I) purified by the above method.

Abstract: A method for the production of spray-dried material in a spray tower, in which the melt fed into the tower is cooled with a counter-current of gas and then discharged from the tower while the gas stream is taken off and transferred directly to a heat exchanger to lower or raise the temperature of the gas.

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.
