Propylene carbonate
Propylene carbonate(CAS NO. 108-32-7) is manufactured by reaction of 1,2-propylene oxide with CO2 in the presence of a catalyst (quaternary ammonium halide). Contaminants include propylene oxide, carbon dioxide, 1,2- and 1,3-propanediols, allyl alcohol and ethylene carbonate. Propylene carbonate can be purified by percolation through molecular sieves (Linde 5A, dried at 350
