The conversion of propylene glycol-acetone mixtures into cyclic ketal over sulforesin Dowex DR-2030 and acidic ZrO2-SiO2 catalysts under steady conditions at 40–100°C has been studied. It has been shown that 2,2,4-trymethyl-1,3-dioxolane can be obtained with 99–94°% yield at 40–50°C. Conversion of p...
