Abstract
Process for obtaining acrylic acid by the catalytic reaction of acetylene with carbon oxide and water at higher temperature and under increased pressure, using an inert solvent and in the presence of carbonyl-forming metal compounds, especially of the iron group, characterized, because the reaction is carried out in solutions which, in addition to water, contain in excess an inert oxygen-organic solvent and such a small amount of the catalyst, that the solutions do not disintegrate under the reaction conditions.
