Abstract


Formation of 2,4-dimethyl-1,3-dioxolane from propylene glycol and acetaldehyde over sulfonic cation-exchange resins and acidic oxides at 10–50°C has been studied . The highest cyclic acetal yield of 83% at 84% propylene glycol conversion was achieved over sulforesin KU-2.8.

Keywords


acid catalysis; 2,4-dimethyl -1,3-dioxolan; propylene glycol; acetaldehyde; sulfonic cation-exchange resin
