    Abstract: A process is disclosed for producing isomer mixtures from O- phenoxyalkylhydroxyl amines Ia: H2N-O-CH2-CH(R1)-O-Ar and Ib: H2N-O-CH(R1)-C H2- O-Ar (wherein R1 represents alkyl, Ar where appropriate a substituted phenyl ) and the corresponding salt mixtures. This process involves the following steps: (a) an isomer mixture of O-(2-hydroxyethyl)-oximes (IIa) and (IIb) (i n which R2 is an alkyl and R3 is an alkyl or alkoxy, or R2 and R3 together wit h the common C atom form a 5-7 member ring) is converted by reaction with a sulphonyl halogenide of formula (III): Hal-SO2-R4 (wherein R4 represents an organic group and Hal is a halogen) in the presence of a base to form the corresponding sulphonate mixture of (IVa) and (IVb); (b) this sulphonate mixture is reacted in the presence of a base with a phenol of formula (V): H O- Ar to produce a mixture of O-phenoxyalkyloximes of general formulae (VIa) an d (VIb); (c) the mixture is hydrolysed in the presence of an acid and, if required, (d) the O-phenoxyalkylhydroxyl amines (Ia) and (Ib) are released from the resulting salts using a mineral base. The O-phenoxyalkylhydroxyl amines (Ia/Ib) and their precursors (VIa/VIb) are important intermediate products for plant protective agents and drugs.

    Abstract: Separation of impurities from 3-(2'-acetoxyethyl)-dihydro-2(3H)-furanone (I) obtained by acetylation of 3-(2'-hydroxyethyl)-dihydro-2(3H)-furanone comprises first separating high boiling impurities and subjecting the recovered distillation head product to a further step in which light and medium boiling components are taken off at the head and recovering pure (I) as the sump product.
