摘要

Novel 2-hydroxypropylimidazole derivatives of the formula I <IMAGE> I <IMAGE> where m is 1 or 2 and n is 0 or 1, R1 is an aliphatic or cycloaliphatic radical of 6 to 21 carbon atoms, R, if n is O, is an aliphatic, cycloaliphatic, aromatic or araliphatic radical of 6 to 21 carbon atoms and is preferably identical with R1, or R, if n is 1, is a divalent aliphatic or aromatic radical of 2 to 15 carbon atoms or is <IMAGE> +TR <IMAGE> p being 0 or 2, and R', R'' and R''' are hydrogen or alkyl of 1 to 4 carbon atoms, and R'' or R''' may also be nitro.
