Decomposition of ethylene carbonate
WebThe mass fraction of sulfolane (ω(SL)) in the EC/SL mixtures varied from 0 to 1 with an increment of 0.05–0.10. Since the melting points of ethylene carbonate and sulfolane … WebThe mass fraction of sulfolane (ω(SL)) in the EC/SL mixtures varied from 0 to 1 with an increment of 0.05–0.10. Since the melting points of ethylene carbonate and sulfolane are above room temperature (≈36 and ≈29 °C, respectively), they were heated until wholly melted (up to 40 °C for EC and up to 30 °C for SL).
