The experimental state parameter values range from 285.9 K to 523.0 K, in temperature, with a mean 327.3 K, and from 1 to 3494 bar in pressure, with a mean of 198 bar (Figures and). Solubility measurements at temperatures above 400 K were sparse, and data for pressures exceeding 500 bar were isolated. The dataset includes compounds exhibiting a wide chemical diversity, featuring 42 unique atom types. Molecular sizes range from 1 to 273 atoms, and molecular weights from 16 to 1819 g mol . The molecular weight distribution closely approximates a normal distribution, with an average value of 325 g mol -1 (Figure ). This suggests that most compounds in the dataset are of medium to high molecular weight.
