Method for producing polyether alcohols
Abstract
The invention relates to an oxide by H- and initial substance of the DMC catalyst with the reaction, and preparation of alcohol ether method for continuously. According to the method: a) cycloalkyl and primary filling material and catalyst DMC the reactor, b) measuring added to the oxidization according to any of 100-3000 seconds and as measurement speed of the reactor is continuous-running, c) in the step b) measuring adding the initial material is as formula of 5-500 seconds and as measurement speed of the reactor is continuous-running, wherein the sealing layer for achieving of the reactor continuous-running, wherein an product from the reactor for. Of to make the sealing layer in the reactor in the temperature of the amount of the initial substance and oxidized oxide, and measuring is added DMC catalyst as to make in the reactor is as catalyst concentration of the reactor is continuous-running.
