Abstract: PROBLEM TO BE SOLVED: To provide a method for removing impurities from 3-(2'-acetoxyethyl)- dihydroxyethyl)dihydro-2(3H)furanone. SOLUTION: In this method, 3-(2'-hydroxyethyl)dihydro-2(3H)furanone including impurities is subjected to plural distillations or purifications and high boiling point impurities are removed, then a product taken out from the top part is subjected to at least other one process, thus a low boiling point component and a middle boiling point component are removed from the top part to obtain pure 3-(2'-hydroxyethyl)dihydro-2(3H)furanone (I) as a column bottom product.

Abstract: The invention relates to a method for producing 2-{1-[2-(4-chlorophenoxy)- propoxyimino]-butyl}-3-hydroxy-5-(tetrahydrothiopyrane-3-yl)-cyclohex-2-enon e lithium salt by reacting the corresponding acid 2-{1-[2-(4-chlorophenoxy)- propoxyimino]-butyl}-3-hydroxy-5-(tetrahydrothiopyrane-3-yl)-cyclohex-2-enon e with lithium hydroxide, and for extracting the lithium salt. It is advantageous to use a solvent mixture containing methanol and at least one aromatic hydrocarbon, and to remove part of the solvent before extraction. I t is especially preferable to dissolve the acid in an aromatic hydrocarbon, preferably toluol, and to use a methanolic lithium hydroxide solution. The product obtained efficiently according to the inventive method also has considerable advantages in terms of formulation techniques.
