8. Mai 2024 · The electro-decarboxylation of carboxylic acids has been studied for over a century, since Hermann Kolbe first identified alkanes and CO 2 formation from acetic and valeric acid.
Vor 6 Tagen · In 1845 German chemist Hermann Kolbe synthesised acetic acid from inorganic compounds for the first time. This reaction sequence consisted of chlorination of carbon disulfide to carbon tetrachloride , followed by pyrolysis to tetrachloroethylene and aqueous chlorination to trichloroacetic acid , and concluded with electrolytic ...
