The melting point of Diethyl carbonate is frequently referred to in the literature as -43 degC. Recently, we conducted some DSC experiments which produced a melting point of around -754degC. The instrument was confirmed to be in calibration and we began a literature hunt. We found 2 papers by Michael S. Ding(ref.1 and 2), describing experimental procedures by DSC, in which he also found the melting point of diethyl carbonate as -74.3degC, confirming our result. One of the main references for the -43degC melting point of diethyl carbonate is in french and dates back to the 1930's (ref 3).
Suppliers of Diethyl carbonate list the melting point at -43degC (lit), but in some literature where the melting point is analysed during the experimental it is reported as -74degC. How can we go about rectifying or highlighting this?
