Measurements of the physical properties of 1-octadecylamine were carried out in a temperature range of 30 to 120°C. The melting point of the compound was observed at 55°C and no liquid crystalline phase was found within this temperature range. The decomposition point of the carbonate of this amine was found to be a little higher than the melting point. A mixture of the amine with a small amount of its carbonate gave DSC curve similar to that of typical liquid crystalline materials.
