1-(2-hydroxyethyl)-5,5-dimethylimidazolidine-2,4-dione

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Thus, to make the non-methylolated hydantoin fatty acid ester, or MHEDMH ester (Ia), 5,5-dimethylhydantoin, or DMH (ii) [C5H8O2N2 =128 mol. wt.], is reacted with ethylene oxide in a first step per reaction scheme (1a), e.g. in the presence of a catalyst such as sodium hydroxide, to form monohydroxyethyl dimethylhydantoin, or 1-(2-hydroxyethyl)-5,5-dimethylhydantoin [i.e., 1-(2-hydroxyethyl)-5,5-dimethyl-1,3-diazacyclopentane-2,4-dione], or MHEDMH (vi) [C7H12O3N2 =172 mol. wt⟧
