Efficient continuous-flow HD exchange reaction of aromatic nuclei in D2O/2-PrOH mixed solvent in a catalyst cartridge packed with platinum on carbon beads

Herein, a continuous-flow deuteration methodology for various aromatic compounds is developed based on heterogeneous platinum-catalyzed hydrogen-deuterium exchange. The reaction entails the transfer of a substrate dissolved in a mixed solvent of 2-propanol and deuterium oxide into a catalyst cartridge packed with platinum on carbon beads (Pt/CB). Pt/ CB could be continuously used without significant deterioration of catalyst activity for at least 24 h. Deuteration proceeded within 60 s of the substrate solutions being passed through the Pt/CB layer in the Pt/CB-packed cartridge.

Synthesis method of paraben compounds marked by stable isotope 13C or D

The invention relates to a synthesis method of paraben compounds marked by a stable isotope 13C or D. In the method, p-hydroxybenzoic acid, which is marked by the stable isotope 13C or D, and an alcohol compound are employed as raw materials for preparing the paraben compounds under the effect of an acidic catalyst p-toluenesulfonic acid. Compared with a synthesis process of the paraben compounds in natural abundance, the method is free of isotope dilution during the reaction process, has mild reaction conditions and high utilization rate on the isotopes. The paraben compounds marked by the stable isotope 13C or D, after separation and purification, are more than 99% in chemical purity and are more than 99 atom% in isotope abundance.
