Abstract
A process for the selective production of defined, partial reaction products of polyfunctional N-glycidyl compounds with hydrohalic acids, pseudohydrohalic acids or acids of phosphorus; mono- or di-ring opening products are obtainable as required. The process is carried out at a pH of from about 2 to 10 which is kept constant within a band of at most 2 units on the pH-scale. N,N'-diglycidyl-N'-(halohydroxypropyl)-urazoles and N-glycidyl-N,N'-bis(halohydroxypropyl) urazoles having pharmaceutical utility are produced in good yield.
