Abstract: An industrial process for the heterogeneously catalytic gas-phase oxidation of propane with molecular oxygen to form acroleine in which, starting with a molar reactant ratio of the propane to the O2 in the undiluted state in the gas mixture fed in of 7:3, said gas mixture is diluted with the reactant propane and possibly inert gases so that the gas mixture fed in has more than 70 vol % propane and at least 5 vol % O2.

Abstract: The production of acrylic acid (I) and/or its esters comprises; (a) catalytic gas-phase oxidation of propene and/or acrolein to give a gaseous product containing (I), (b) absorption of the reaction product with a solvent, (c) distillation in a column to give crude (I) and solvent, (d) purification of (I) by crystallisation and optionally (e) esterification of crystallised (I). Also claimed is an apparatus for the process, comprising reactor(s) for stage (a), an absorption column, a distillation column, dynamic crystalliser(s) and static crystalliser(s), and container(s) for intermediate storage.

Abstract: Paper, cardboard and board having high dry strength, wet strength and alkali resistance are produced by adding resin solutions, which are obtained by reacting homopolymers and copolymers of vinylimidazoles with epichlorohydrin in a ratio of from 0.02 to 2.9 moles of epichlorohydrin per equivalent of basic nitrogen in the polymer, to the paper stock and then draining the latter on a screen to form sheets.
