    摘要: The present disclosure relates to a recycling method for producing dimethyl carbonate and dimethyl carbonate derivatives. The process is unique in that it produces a by-product that can be re-used in the process as a raw material for repeating the process. For example, when the process is directed to synthesizing dimethyl carbonate, glycerol is used as a starting material. Glycerol is also a by-product produced during formation of dimethyl carbonate, and therefore it can be re-used as starting material to generate more dimethyl carbonate.

    摘要: The present disclosure provides for a process for an equilibrium limited reaction using reactive chromatography unit (RCU) in which a first organic donor reactant (FODR) and a second organic acceptor reactant (SOAR) react to form a product mixture of a first acceptor product (FAP) and a second donor co-product (SDCP). The equilibrium-limited reaction does not produce water. The RCU has separation media to separate the product mixture into a raffmate and an extract. The FODR is in a stoichiometric deficit relative to the SOAR for the equilibrium limited reaction, so that the SOAR acts as the eluent for both the raffmate and the extract, and so as not to produce an azeotrope of FODR and the SDCP in the extract.
