The density of petroleum products in a wide range of parameters of state

The density of liquid products of catalytic cracking (CC) and viscosity breaking (VB) is measured in the temperature range from $293$ K to $473$ K at atmospheric pressure and at pressures elevated to $60$ MPa. The resultant data are generalized along with experimental data on the density of directly distilled liquid petroleum fractions and commercial petroleum products. Dependences are obtained, which are suitable for determining the density of a wide range of petroleum products in view of the special features of their hydrocarbon composition.
