Abstract: The present invention relates to a method of redissociating Michael adducts of acrylic acid present in a liquid F in a redissociation apparatus comprising at least one separating column K, an evaporator V and a pump P, wherein, in the event of an unwanted rise in the viscosity of the residue R in the bottom space of the separating column K, the feed of the liquid F into the redissociation apparatus is stopped, the residue R in the bottom space of the separating column K is diluted and cooled with a solvent 1, and the bottom space of the separating column K is emptied.

Abstract: The present invention relates to a method for the regioselective hydroformylation of polyunsaturated acyclic hydrocarbons, which are 1, 3 butadienes, which, in the 2 position, bear a saturated or monounsaturated or polyunsaturated acyclic hydrocarbon radical. The present invention also relates to the production of secondary products of these hydroformylation products, especially of ambrox.

Abstract: A process for preparing acrylic acid, in which heterogeneously catalyzed gas phase partial oxidation of at least one C3 precursor of acrylic acid with molecular oxygen over catalysts in the solid state of matter at elevated temperature affords a product gas mixture comprising acrylic acid, water vapor and secondary components, then the product gas mixture is directed into a condensation column equipped with separating internals, the product gas mixture is allowed to ascend into itself within the condensation column and undergoes fractional condensation, separating the product gas mixture into a bottoms liquid comprising conversion products and secondary components that are higher-boiling than acrylic acid, a crude acrylic acid comprising water and secondary components that have been depleted overall as target product, an acid water still comprising acrylic acid and secondary components, and a residual gas mixture comprising secondary components that are lower-boiling than water, the target product is conducted out of the condensation column via a side draw and the side draw is above the feed point of the product gas mixture into the condensation column, wherein the parts of the condensation column that are in contact with product are made of stainless steel, at least one of the streams of matter fed to the condensation column comprises a source for halide ions, and halide ions are removed in the region of the separating internals of the condensation column above the side draw.
