  • Patent number: 10807961
    Abstract: A method for producing propylene oxide involves an oxidation step, a distillation step, an epoxidation step, and a separation step. The distillation step involves distilling the reaction mixture containing cumene hydroperoxide to separate it into a concentrate containing cumene hydroperoxide and a distillate. The reaction mixture is continuously distilled so that the ratio of the flow rate of the distillate to the flow rate of the reaction mixture to be distilled is 0.037 to 0.13. The epoxidation step involves obtaining a reaction mixture containing propylene oxide and cumyl alcohol by contacting the concentrate with propylene in the presence of a catalyst in one or more reactors to cause a reaction between propylene and cumene hydroperoxide in the concentrate, in which the outlet temperature of the final reactor is adjusted to 115° C. or more and less than 140° C.

    Abstract: A 4,5-disubstituted-1H-pyrrolo(2,3-f)quinolin-2,7,9-tricarboxylate compound, or an analog, or derivative thereof, having a structure of Formula I: R1 and R4 are each independently an atom or group selected from hydrogen, a linear or branched C1-8 alkyl group, a deuterated linear or branched C1-8 alkyl group, an aralkyl group, or a substituted aryl group; R2 is independently an atom or group selected from halogens, a linear or branched C1-8 alkoxy group, or a deuterated linear or branched C1-8 alkoxy group; and R3 is independently an atom or group selected from a linear or branched C1-8 alkoxy group, or a deuterated linear or branched C1-8 alkoxy group. The compound is useful as a reaction intermediate for the synthesis of PQQ. A process in which CAN is used as an oxidant in the synthesis of PQQ in existing patents and literatures is replaced. This makes the process cheaper and more efficient.
