The present invention relates to microcapsules comprising a core, wherein the core comprises cinmethylin, and a polyurea shell, wherein the shell comprises a polyaddition product of diphenylmethane diisocyanate or an oligomer thereof and at least one amine having at least two primary amino groups; to a composition comprising such microcapsules; to a method for preparing such microcapsules or such a composition; to a composition obtainable by said preparation method; and to the use of such microcapsules or compositions for controlling undesired vegetation.

Microcapsules comprising cinmethyln in the core and a polyurea derived from diphenylmethane diisocyanate or an oligomer thereof

The present invention relates to a composition containing microparticles which comprise cinmethylin and a polymeric material which surrounds or embeds cinmethylin, and at least one herbicide different from cinmethylin. The invention further relates to a method for preparing such compositions and the use of such compositions for controlling undesired vegetation.

Composition comprising cinmethylin-containing microparticles and a further herbicide

Aqueous formulations comprising (A) at least one organic complexing agent selected from (A1) alkali metal salts of aminopolycarboxylic acids and (A2) polymers bearing at least two &#x2014;CH&#x2014;N(CHCOOH)-units per molecule, partially or fully neutralized with alkali, (B) at least one salt of at least one of the following acids: nitric acid, sulphuric acid, sulphamic acid, methanesulfonic acid, C-C-carboxylic acids, C-C-hydroxymonocarboxylic acids, C-C-dicarboxylic acids, unsubstituted or substituted with hydroxyl, and C-C-tricarboxylic acids, each unsubstituted or substituted with hydroxyl, (C) at least one compound selected from (C1) phosphoric acid C-C-monoalkyl esters, (C2) a C-C-alkynol, optionally alkoxylated with one to 10 alkoxide groups per hydroxyl group, and (C3) a C-C-alkynediol, optionally alkoxylated with one to 10 alkoxide groups per hydroxyl group, said aqueous formulations having pH values in the range of from 7.5 to 10.

Aqueous formulations with good storage capabilities

Process for making membranes M comprising the following steps: a) providing a dope solution D comprising at least one polymer P and at least one solvent S, b) adding at least one coagulant C to said dope solution D to coagulate said at least one polymer P from said dope solution D to obtain a membrane M, wherein said at least one solvent S comprises more than 50% by weight of at least one compound according to formula (I) (I), wherein Rand Rare independently Cto Calkyl, Ris selected from H or an aliphatic rest, 20 Ris selected from H or an aliphatic rest, AO represents at least one alkylene oxide, n is a number from 0 to 100. 

Process for making membranes

The present invention relates to a method of separating radioactive elements from a mixture, wherein the mixture is treated with at least one alkanesulfonic acid and at least one further acid, selected from the group consisting of hydrochloric acid, nitric acid, amidosulfonic acid and mixtures thereof and also the use of at least one alkanesulfonic acid and at least one further acid for separating radioactive elements from mixtures comprising these.
