반응 단계

Into a 3 oz. Fischer-Porter glass aerosol reaction vessel was placed a magnetic stirring bar and 10 mL of an aqueous solution containing glycolic acid (750 mM), ethylene diamine (865 mM), FMN (0.01 mM), propionic acid (HPLC internal standard, 75 mM), and 5% Ru on Al2O3 (1.39 g, 14,000 IU). The final pH of this solution was 9.1. The reaction vessel was sealed and the reaction mixture was cooled to 15° C., then the vessel was flushed with oxygen by pressurizing to 70 psig (483 kPa) and venting to atmospheric pressure five times with stirring. The vessel was then pressurized to 70 psi (483 kPa) of oxygen and the mixture stirred. Aliquots (0.10 mL) were removed through a sampling port (without loss of pressure in the vessel) at regular intervals for analysis by HPLC to monitor the progress of the reaction. After 21 hours, the HPLC yields of glyoxylate, oxalate, and formate were 0.6%, 0%, and 0%, respectively, and 97% glycolate remained.
