Abstract : The melting point of an organic solid can be determined by placing a small amount of the solid in a small capillary tube, affixing the tube to the stem of a thermometer centred in a heating bath, heating the bath slowly, and observing the temperatures at which melting begins and ends. Pure samples typically have sharp melting points, such as 148.5-149 °C or 168-169 °C; impure samples of the same compounds melt at lower temperatures and over a larger temperature range, such as 135-138 °C or 196-199 °C.
