Abstract
Process for obtaining organic acids characterized by the fact that olefins and carbon oxide are used in the reaction in the presence of catalysts such as sulfuric acid or hydrogen fluoride and that the chemical process is carried out in the liquid phase without addition of water with catalysts containing little water in certain cases also in the presence of anhydrous catalysts using for such purposes in particular sulfuric acid in a concentration of at least 90% pure anhydrous hydrogen fluoride or mixed with certain amounts of hydrogen fluoride of boron and collecting the product of the reaction in water from which said product is finally separated by a process known, for example, by distillation of the steam or by means of extraction.
