An equation of state for saturated liquids (TONG'S EOS) was used to estimate saturated liquid densities of gravimet-rically prepared binary mixtures containing the major components of liquefied natural gas (LNC), i. e nitrogen and low-carbon alkanes, within the temperature range of 105K～140K. The model equation was tested for prediction of the saturated densities of LNC mixtures using all the pure components. The advantage of this method was simple and convenient in use.
