Production of valuable chemicals from furfural through hydrotreatment requires information of hydrogen solubility in furfural and the most often applied solvent, 2-propanol. This study investigates hydrogen solubility in furfural and 2-propanol at the temperature range of 323-476 K and pressure range up to 12.5 MPa. The measured data are compared to prediction with Soave-Redlich-Kwong, Peng-Robinson, and Perturbed-Chain Statistically Associating Fluid Theory (PC-SAFT) equations of state. The most accurate prediction of hydrogen solubility in furfural and 2-propanol was obtained with PC-SAFT.

IntroductionPhytochemicals are used in many products, including foods, beverages, pharmaceuticals, and cosmetics. The extraction of phytochemicals is considered one of the best solutions to valorize these underestimated materials. Many methods have been developed to efficiently extract phytochemicals at high quality, high purity, and low costs without harming the environment. Recently, molecular hydrogen (H2) has shown its ability to improve the extraction of phytochemicals from plant materials. Due to its unique physicochemical and biological properties, H2 showed an efficient ability to extract phenolics and antioxidants at high yields with cost‐effective potential. Without sophisticated equipment and high energy and solvent consumption, the hydrogen extraction method is a green and applicable alternative for the extraction of phytochemicals.ObjectivesThis review aims to provide the latest knowledge and results concerning the studies on using hydrogen‐rich solvents to extract phytochemicals from different agri‐food wastes, by‐products, and other plant materials.Materials and MethodsRecent literature relating to extracting phytochemicals by the hydrogen‐rich solvent method and its potential mechanisms is summarized to provide a basic understanding of how hydrogen can improve the extraction of phytochemicals.ResultsThis review describes, for the first time, the practical procedure of how researchers and laboratories can apply the hydrogen extraction method under safe conditions at a low‐budget scale. The review provides some examples of the hydrogen extraction method and the mechanisms and rationale behind its effectiveness.ConclusionsIt can be concluded that the hydrogen‐rich solvent method is a green and cost‐effective method for extracting phytochemicals from different plant materials.

“…With hydrogen, the increase of temperature increases solubility but with other gases the trend is opposite. [135][136][137][138] Hydrogen solubility in furfural has remained unstudied in the past. This is most probably caused by the instability of furfural at higher temperatures and due to the fast reactions with hydrogen.…”
