ABSTRACT:
In a process for the production of tertiary carboxylic acids, especially by "Koch synthesis", the byproducts, e.g., a dimer of tripropene, are removed from the reaction mixture by azeotropic rectification with alkanediols, e.g., 1,3-butanediol, as entrainers, thus obtaining the tertiary carboxylic acids in pure form.
