Patent ID: 7968747

Claim:
A process for preparing aminoglycol of the formula (I) comprising as steps (a) the reaction of a ketoxime of the formula (II) with ethylene oxide in aqueous solution and in the presence of a base where R1 and R are each independently unsubstituted or mono- or poly-halogen-, —CN, —NO 2 -substituted linear (C 1 -C 8 )-alkyl, phenyl or branched (C 3 -C 8 )-alkyl, but, in the case that R1 or R is an unsubstituted or halogen-, CN—, NO 2 -substituted linear (C 1 -C 8 )-alkyl, the other R1 or R radical in each case corresponds to an unsubstituted or halogen-, CN—, NO 2 -substituted phenyl or a branched (C 3 -C 8 )-alkyl, and (b) the further reaction of the 2-hydroxyethyl ketoxime of the formula (III) formed in reaction step (a) in the presence of an acid to give aminoglycol.
