Comparison of experimental densities for [bmim][BF₄] (⚪-298,34 [18]; □-313,01 [18]; △-322,85 [18]; ♢-332,73 [6]; ■-313,1 [14]; ♦-332,6 [14]; ▲-352,6 [14]) with those calculated: (a) by the Tait EOS [14] (in a working range via the interval 10 K thick continuous curves); (b) by the Sanchez-Lacombe EOS [14] (thick dashed curves); (c) by the FT-EOS (thin continuous curves).
