実験手順
The oxidation zone consisted of a vertical, glass tube oxidizer 60 inches (152.4 cm) in length and 2 inches (5.1 cm) in diameter having a capacity of 3.7L and equipped with inlets at the base for feeding air and the hydrolysis zone effluent. The top of the oxidizer was equipped with, in order, a heater exchanger for condensing acetic acid and water from the oxidizer vapor effluent, a vapor/liquid separator, a pressure-regulating valve, a trap cooled to -67° C. by dry ice (solid carbon dioxide) and a scrubber. The oxidizer is charged initially with an acetic acid solution containing 5 weight percent water and 0.3 weight percent cobalt, provided as cobalt hydrate or cobalt acetate. The oxidizer is heated to 130° C. by means of an electric heating cable and pressurized with air which was sparged to the bottom of the oxidation vessel while feeding either acetaldehyde or the EDA hydrolysis product.
