ABSTRACT:
New dialcohols of mononuclear, five-membered or six-membered, unsubstituted or substituted N-heterocyclic compounds which contain two NH-groups in the molecule, by reaction of mononuclear, five-membered or six-membered, unsubstituted or substituted N-heterocyclic compounds, for example hydantoin, barbituric acid, uracil, dihydrouracil, parabanic acid and the corresponding derivatives, with ethylene oxide or propylene oxide to give dialcohols. These diols are useful as intermediates for the preparation of polymers, such as polyesters or polyurethanes, or of epoxy resins.
