Abstract

Zgłoszenie dotyczy procesu otrzymywania oksyalkilatów w reakcji addycji co najmniej jednego tlenku alkilenowego do startera będącego substancją chemiczną zawierającą co najmniej jeden aktywny atom wodoru w obecności katalizatora zasadowego, prowadzony w reaktorze obiegowym. W procesie według zgłoszenia krotność cyrkulacji K<sub>C</sub> [h<sup>-1</sup>] wyrażona jako stosunek objętościowego przepływu cieczy obiegowej reaktora V [m<sup>3</sup>/h] do objętości cieczy w reaktorze Vc [m<sup>3</sup>] określona równaniem (1): K<sub>c</sub>=V/Vc (1) wynosi co najmniej 10 h<sup>-1</sup>.The application concerns the process of obtaining oxyalkylates by the addition of at least one alkylene oxide to a starter, which is a chemical substance containing at least one active hydrogen atom in the presence of a basic catalyst, carried out in a circulating reactor. In the process as reported, the circulation multiplicity K<sub>C</sub> [h<sup>-1</sup>] expressed as the ratio of the volume flow of the reactor circulating liquid V [m<sup>3</sup>/h] to the volume of liquid in the reactor Vc [m<sup>3</sup>] defined by equation (1): K<sub>c</sub>=V/Vc (1) is at least 10 h<sup>-1</ sup>.
