titleOfInvention | Process for the continuous production of polyoxyalkylene polyols |
abstract | The invention relates to a process for producing a polyoxyalkylene polyol, comprising depositing an alkylene oxide onto an H-functional starter substance in the presence of a double metal cyanide (DMC) catalyst, wherein the alkylene oxide is dosed at the mass flow rate m(alkylene oxide), the H-functional starter substance is dosed at the mass flow rate m(starter substance), and the double metal cyanide (DMC) catalyst is dosed in a dispersant at the mass flow rate m(DMC) continuously into the reactor with the reaction volume V during the reaction, and the resulting reaction mixture is continuously removed from the reactor, and wherein the quotient of the sum of the mass flow rates Σ{dot over (m)} of {dot over (m)}(alkylene oxide), {dot over (m)}(starter substance) and {dot over (m)}(DMC) to give the reaction volume V in the steady state is greater than or equal to 1200 g/(h·L). |
