Preparation of polyether polyols containing aromatics |
| abstract |
In a process for preparing polyether polyols containing aromatics by molecular addition of alkylene oxides to H-functional initiators at from 70 DEG C. to 135 DEG C. and pressures of from 0.1 MPa to 1.0 MPa, the alkoxylation is carried out using at least one initiator comprising at least 95% by weight of 2,3 and 3,4 isomers of tolylenediamine, from 0.5 to 4% by weight of 2,4 and 2,6 isomers of tolylenediamine and from 0.1 to 1.5% by weight of more volatile fractions from tolylenediamine production. The polyether polyols prepared by this process can be used as component of a polyol mixture for producing rigid polyurethane foams. |
