Measurement of the thermal conductivities of 2-Amino-2-methyl-1,3-propanediol (cas 115-69-5) (AMP), 2-amino-2-hydroxymethyl-1,3-propanediol (TRIS) and the mixture (AMP+TRIS, mole ratio 50:50) in the temperature range from 20°C to their supermelting temperatures

2-Amino-2-methyl-1,3-propanediol (cas 115-69-5) (AMP), 2-amino-2-hydroxymethyl-1,3-propanediol (TRIS) and the mixture (AMP+TRIS, mole ratio 50:50) are being considered as potential candidates for the thermal storage of energy. The thermal conductivities have been measured with an uncertainty of ±3% from 20°C to the supermelting points of these substances by means of a calorimeter equipped with a thermistor. The experimental thermal conductivities of the substances under investigation are smoothed by fitting for different values of temperature and reported at intervals of 10 K. In addition, the solid–solid transition and melting temperatures are also determined to be 80 and 108°C for AMP, 135 and 175°C for TRIS and 70 and 142°C for (AMP+TRIS), based on the thermal conductivity–temperature diagrams of these substances.
