Abstract
New mono- or 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 butene oxid, 1,2-cyclopentene oxide or 1,2-cyclohexene oxide to give monoalcohols or dialcohols. These compounds are useful as intermediates for the preparation of diglycidyl compounds as set forth in German Offenlegungsschrift No. 2,104,259.
Claims6
A mono- or dialcohol of the formula
- wherein Y.sub.1 and Y.sub.2 each denotes hydrogen or methyl and Y.sub.3 and Y.sub.4 each denotes methyl or ethyl, the sum of the carbon atoms in Y.sub.1 and Y.sub.3 or Y.sub.2 and Y.sub.4 having always to be 2, or wherein Y.sub.2 and Y.sub.4 together denote trimethylene or tetramethylene, and Z represents a member selected from the group consisting of a divalent residue of the formulae ##STR12## wherein R', R", R"' and R"" each represents a member selected from the group consisting of alkyl with 1 to 4 carbon atoms, alkenyl with 2 to 4 carbon atoms, cyclohexyl, cyclohexenyl, and phenyl, or when Z represents the formula ##STR13## R' and R" together denote tetramethylene and pentamethylene, and m and n each represents an integer having a value of 0 to 30 with the sum of m and n having to be at least 1.
