Abstract
IT is found that the thermal expansion of the crystal lattice of n-paraffins is not equal in all directions.1 The increase in length of the a axis measured in the range of liquid air temperature to room temperature is about 7 per cent, of the b axis about 2 per cent, whereas the c axis remains practically unaltered. This axis is parallel to the chain axes of the molecules.
