Original Measurements
Tsindrik, N. M.; Zh. Obshch. Khim. 28, 830-4 (1958).
Variables:
Prepared by:
Method/Apparatus/Procedure:
A visual polythermal method was used. The temperatures were measured with a Nichrome-Constantan thermouple.
Source and Purity of Materials:
- Analytical grade materials were recrystallized twice. The extrapolated fusion temperature of the lithium formate was 273°C.
Estimated Errors:
Ambient temperature: The compiler estimates the accuracy of the temperature measurements to be probably ±2 K.
Mass concentration (m/v) (1): No information is given.
Experimental Values:
Note: Note 1: There is a eutectic at 162°C and 100x1=55.Note 2: The system was investigated at 0≤100x1≤80.
