Wang, Xiaoda (author), Zhao, Yuqing (author), Han, Lumin (author), Li, Ling (author), Kiss, A.A. (author)Cylcohexanol is an essential bulk chemical that can be produced via cyclohexene hydration, a liquid-liquid two-phase reaction that is limited by the low reaction rate and the equilibrium conversion. Adding an appropriate solvent is the most promising method to break through these limitations. However, in previous works the solvent was almost...journal article 2023
