Abstract The solubility data of functional compounds in supercritical carbon dioxide were compiled and discussed. The investigation included essential oils, phenolic compounds, carotenoids, tocopherols, carboxylic acids, alkaloids and vitamins. The data were correlated with four mathematical models. The parameters of each model were adjusted for each compound using the experimental data from literature. From the evaluation of the compiled data, it was possible to observe that the essential oils are the most soluble compounds and the phenolic compounds are the least soluble compounds in supercritical CO2, in the range of temperatures and pressures that were evaluated. In relation to the models, it was observed that the prediction of the solubilities of the biocompounds in supercritical fluids was acceptable for all the models, with the Jiang et al. equation being the model that presented the best results to predict the solubility for all functional groups.

功能化合物在超临界 CO2 中的溶解度：数据评估和建模

摘要 对功能化合物在超临界二氧化碳中的溶解度数据进行了整理和讨论。调查包括精油、酚类化合物、类胡萝卜素、生育酚、羧酸、生物碱和维生素。数据与四个数学模型相关。使用文献中的实验数据针对每种化合物调整每个模型的参数。从对汇编数据的评估中，可以观察到，在所评估的温度和压力范围内，在超临界 CO2 中，精油是溶解度最高的化合物，酚类化合物是溶解度最低的化合物。关于模型，观察到生物化合物在超临界流体中溶解度的预测对于所有模型都是可以接受的，Jiang 等人。
