Abstract: The invention relates to a method for the heterogeneously catalysed partial gas phase oxidation of propylene to form acrylic acid. According to said method, the reaction starting mixture contains cyclopropane as an impurity, and the acrylic acid is separated off by means of separation by crystallisation after being transformed from the product gas mixture into the condensed phase.
