Abstract: A process for manufacturing a substituted cyclohexanecarbonitrile said process comprising the following steps: —reacting the corresponding substituted cyclohexanecarboxylic acid with thionyl chloride to make the corresponding acyl chloride; and simultaneously or subsequently —reacting the chloride with sulfonamide in sulfolane as solvent to make the substituted cyclohexanecarbonitrile.

Abstract: Process for manufacturing an aqueous hydrogen peroxide solution comprising the following steps: —hydrogenating a working solution which comprises an alkylanthraquinone and/or tetrahydroalkylanthraquinone and a mixture of a non-polar organic solvent and a polar organic solvent wherein the concentration of non-polar organic solvent in said mixture is equal to or higher than 30 wt %; —oxidizing the hydrogenated working solution to produce hydrogen peroxide; and —isolating the hydrogen peroxide, wherein the polar organic solvent is a substituted cyclohexane carbonitrile.

Abstract: A process includes preparing a crude aqueous hydrogen peroxide solution by auto-oxidation of at least one alkylanthraquinone in a working solution that includes at least one organic solvent and the at least one alkylanthraquinone; and washing the crude aqueous hydrogen peroxide solution with a mixture of at least one organic solvent and an organophosphorous chelating agent to create a purified aqueous hydrogen peroxide solution having less than 100 ppb Cr; wherein the organic solvent used for the washing is not part of the working solution and is not recycled into it.

Abstract: A process for preparing coated particulate alkali metal percarbonate in which coating is carried out by mixing percarbonate with a solid particulate coating and agent and optionally with an aqueous liquid, so that the amount of water present during mixing does not exceed 12% of the total weight of the mixture. Coated alkali metal percarbonate obtainable by this process and its use as active bleach in detergent compositions is also disclosed.
