摘要：
A method for the heterogeneously catalyzed partial direct oxidation of propane to acrylic acid in the gas phase, in which the reaction gas inlet mixture comprises cyclopropane as an impurity and the acrylic acid, after it has been converted from the product gas mixture into the liquid phase, is operated from the other constituents of the liquid phase with the aid of a separation by crystallization.
