摘要： A process for conducting equilibrium-limited chemical reactions that produce water as a reaction product. Specifically, a process that uses a reactive chromatography unit (RCU) to improve the efficiency of equilibrium-limited reactions, such as a process for reacting glycol ether (GE) and carboxylic acid (CA) to form water and glycol ether ester (GEE). The process includes supplying GE and CA to the RCU, where one of either the CA or the GE is in a stoichiometric deficit relative to the other reactant. The reactant in the stoichiometric deficit reacts in the presence of the catalyst in the RCU to form a mixture of GEE and water. A raffinate is separated from the mixture using the separation media of the RCU contains at least the GEE. An extract separated from the mixture using the separation media of the RCU contains at least the water.

摘要： The present disclosure provides for a process for supplying a first reactant and a second reactant (reactants) to a simulated moving bed reactor (SMBR) at each step of a sequential repeating injection cycle, where the SMBR includes zones each having an injection point and each containing a solid separation media; reacting the reactants in the SMBR during the sequential repeating injection cycle (cycle) to form a first product; separating the first product in the SMBR with the solid separation media; and changing an amount of one or both of the reactants injected at one or more of the injection points of the SMBR during a step of the cycle. Changing the amount of the reactants can be done at each step of the sequential repeating injection cycle. Changing the amount can include changing an inlet concentration of the reactants injected at one or more of the injection points during each step of the cycle.
