摘要： 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.

摘要： Prodn. of acrolein (I) and/or acrylic acid (II) from C3H8 involves (A) gas phase partial dehydrogenation of C3H8 to C3H6, using heterogeneous catalyst; (B) using the prod. gas mixt. of C3H6 and unreacted C3H8 for charging an oxidn. reactor, in which C3H6 is converted to (I) and/or (II) by gas phase selective partial oxidn. with pure O2 using heterogeneous catalyst; and (C) separating the prod. from the prod. gas stream and recycling at least the unreacted C3H8 from stage (B) to stage (A). The novelty is that, before entering stage (B), constituents other than C3H8 and C3H6, at least H2 and steam, are removed from the prod. gas mixt. from stage (A). Pref. all constituents except C3H8 and C3H6 are removed after stage (A). Stage (B) is carried out in 2 consecutive reactors charged with multi-metal oxide catalysts, the first of Mo-Bi-Fe and the second of Mo-V. The prod. gas mixt. from the first oxidn. reactor is passed directly into the second; and the vol. ratio of organic cpd. for partial oxidn. (C3H6 or (II)) to O2 is 1:(1-3) in both reactors.

摘要： A process for preparing acrolein or acrylic acid or a mixture thereof from propane, in which the propane is initially dehydrogenated under heterogeneous catalysis to give propene, secondary components are removed and the remaining gas mixture, comprising propane and propene, is subjected to the heterogeneously catalyzed partial oxidation to acrolein or acrylic acid or a mixture thereof as the target product, target product is removed from the product gas mixture and the remaining residual gas, comprising excess oxygen and unconverted propane, is recycled into the propane dehydrogenation in such a way that the other propane fed to the dehydrogenation is at least partly converted under dehydrogenating conditions at the recycle point.
