Abstract
The invention relates to a process for preparing polyether alcohols by reacting a) aromatic amines with b) alkylene oxides in the presence of c) a catalyst, wherein the alkylene oxide b) comprises at least 90% by weight, based on the weight of the component b), of propylene oxide and an amine is used as catalyst c).
Claims10
A process for preparing polyether alcohols by reacting a) aromatic amines comprising tolylenediamine with b) alkylene oxides in the presence of c) 0.01 to 0.5% by mass of a catalyst comprising imidazole, wherein the alkylene oxide b) comprises at least 90% by weight, based on the weight of the component b), of propylene oxide,
- wherein said aromatic amines and said alkylene oxides are reacted at a temperature of from 90 to 150° C.
