 Variables:


Prepared By:
   P. Baldini

 Experimental Remarks:
   Note: The system was investigated at 0≤100x1≤30 due to thermal instability of component 1. A eutectic is present at 252 ºC and 100x1 = 21.

 Notes:
   a  The T/K values were calculated the compiler.

 Method/Apparatus/Procedure:
   A visual polythermal method was used.

 Source and Purity of Materials:
   The materials were prepared by reacting C.P. carbonates with a slight excess of formic acid.1
Component 1 undergoes a phase transition at 140 °C.2
Component 2 undergoes a phase transition at 242 °C.2

 Estimated Errors:
   Solubility: No information is given.
   Temperature: The compiler estimates the accuracy of the temperature measurements to be probably ± 2 K.
