Abstract: PROBLEM TO BE SOLVED: To provide a new method for production of acrylic acid by means of heterogeneously catalyzed partial gas phase oxidation of propylene. SOLUTION: There is disclosed the method for producing acrylic acid by means of heterogeneously catalyzed partial gas phase oxidation of propylene in two steps, wherein the propylene used is obtained by previous dehydrogenation of propane; a first oxidation step is operated along with the limited propylene conversion; and unconverted propane and the propylene in the product gas mixture of a second step of partial oxidation are substantially recycled by supplying them into the previous propane dehydrogenation process.

Abstract: A process for producing a liquid formulation of salts of sulfonated azo dyes by coupling an at least equimolar amount of diazotized aminoarylsulfonic acids I H2N—Ar—SO3H (I), where Ar is phenylene (which may be monosubstituted by sulfo) or naphthylene (which may be mono- or disubstituted by sulfo and/or monosubstituted by hydroxyl) onto the coupling product of an unsubstituted or methyl-substituted phenylenediamine with itself comprises dissolving the azo dye in a basic medium and then subjecting the solution to a nanofiltration.

Abstract: The present invention provides a process for preparing 1,6-hexanediol from a carboxylic acid mixture which comprises adipic acid, 6-hydroxycaproic acid and small amounts of 1,4-cyclohexanediols and is obtained as a by-product in the oxidation of cyclohexane to cyclohexanone/cyclohexanol with oxygen or oxygen-containing gases and by water extraction of the reaction mixture, by esterification of the acids and hydrogenation, in which a) the mono- and dicarboxylic acids present in the aqueous dicarboxylic acid mixture are reacted with a low molecular weight alcohol to give the corresponding carboxylic esters, b) the resulting esterification mixture is freed of excess alcohol and low boilers in a first distillation stage, c) a separation of the bottom product is carried out in a second distillation stage into an ester fraction substantially free of 1,4-cyclohexanediols and a fraction comprising at least the majority of the 1,4-cyclohexanediols, d) the ester fraction substantially free of 1,4-cyclohexanediols is catalytically hydrogenated and e) 1,6-hexanediol is obtained in a purifying distillation stage from the hydrogenation effluent while removing an alcohol-low boiler mixture in a manner known per se, wherein alcohol is removed by a membrane system from the mixtures, obtained after the esterification in stage b) and/or after the hydrogenation in stage e), of alcohols and low boilers and recycled into the esterification.

Abstract: The stream containing hydrogen chloride (I) and the stream containing oxygen (II) are fed into an oxidation zone. The hydrogen chloride is oxidized to chlorine. A gas and a water-free gas streams are remained through the cooling and drying. The stream reversal contains chlorine-rich, chlorine, oxygen and carbon dioxide, and the liquefaction is carried out by compression and cooling (6). The gas and the water-free gas streams contain chlorine, water, oxygen, carbon dioxide and inert gases. The Gas/liquid stream is separated into a gas stream containing chlorine, oxygen, carbon dioxide and inert gases and into a fluid stream containing chlorine, oxygen and carbon dioxide. The gas stream is fed into a membrane separation unit (9) and separated into the stream reversal and chlorine-poor, chlorine, oxygen and carbon dioxide containing gas by membrane separation. The liquid stream is separated into a chlorine stream and a stream containing oxygen and carbon dioxide by distillation. The chlorine-poor and the gas stream are led into the oxidation zone, and the chlorine poor is removed.
