Abstract: The invention relates to oil suspension concentrates based on 2-{1-[2-(4- chlorophenoxy)-propoxyimino]-butyl}-3-hydroxy-5-(tetrahydrothiopyran-3-yl)- cyclohex-2-enone lithium salt and certain formulation auxiliary agents, in addition to the use of said oil suspension concentrates as plant protecting agents, especially rice herbicides. Preferred formulation auxiliary agents a re monocarboxylic and/or dicarboxylic acid esters, e.g. liquid fatty acid ester s; anionic surfactants such as sulfonates, e.g. alkyl and alkylaryl sulfonates and sulfosuccinates; and non-ionic surfactants such as optionally ethoxylate d carboxylic acids and esters of monofunctional or polyfunctional alcohols, e. g. ethoxylated fatty acids and polyoxyethylene sorbitan fatty acid esters. The aforementioned oil suspension concentrates are stable in storage and have excellent properties of use.

Abstract: The present invention relates to oil suspension concentrates based on 2-{1-[2-(4-chlorophenoxy)propoxyimino]butyl}-3-hydroxy-5-(tetrahydrothiopyran-3-yl)cyclohex-2-enone lithium salt and certain formulation auxiliaries and to the use of the oil suspension concentrates as crop protection compositions and in particular as rice herbicides. Preferred formulation auxiliaries are mono- and/or dicarboxylic esters, for example fluid fatty acid esters, anionic surfactants of the sulfonate type, for example alkyl- and alkylarylsulfonates and also sulfosuccinates, and nonionic surfactants of the type of the nonethoxylated or ethoxylated carboxylic acids and esters of mono- or polyfunctional alcohols, for example ethoxylated fatty acids and polyoxyethylene sorbitan fatty acid esters.The oil suspension concentrates described herein are storage-stable and have excellent use properties.

Abstract: A process for removing impurities from 3-(2'-acetoxyethyl)-dihydro-2(3H)-furanone (I), which comprises initially preparing the 3-(2'-acetoxyethyl)-dihydro-2(3H)-furanone containing the undesirable impurities in a manner known per se by acetylating 3-(2'-hydroxylethyl)-dihydro-2(3H)-furanone, subsequently treating it with strong mineral acids and finally removing the decomposition products of the undesirable impurities from I.
