The high pressure density data of six substances which are potential liquid organic hydrogen carrier systems (LOHCs) (toluene and methylcyclohexane, N-ethylcarbazole and dodecahydro-N-ethylcarbazole, dibenzyltoluene and octadecahydro-dibenzyltoluene) have been measured within pressure range of (1 to 25) MPa within wide range of temperature varying from 293.15 K to 523.15 K. The experimental data were correlated as a function of temperature and pressure using Tait equation. The experimental data were compared with correlated data, resulting in absolute average deviation (AAD = 0.10 %), maximum deviation (MD = 0.30 %), and standard deviation (σ = 1.12 × 10⁻⁴ g·cm⁻³).

潜在液态有机氢载体的高压密度数据的实验测量和相关性

在压力范围（1至25）在从293.15 K到523.15 K的宽温度范围内的MPa。使用Tait方程将实验数据与温度和压力的函数相关。将实验数据与相关数据进行比较，得出绝对平均偏差（AAD = 0.10％），最大偏差（MD = 0.30％）和标准偏差（σ= 1.12×10 ^-4 g·cm ^-3）。
