Vorschrift

50.0 g of gluconolactone is dissolved in 950 ml demineralised water. The pH is adjusted to 6.0 with 25 g of a 45% w/w sodium hydroxide solution. The solution is heated to 55° C. under nitrogen, until no more oxygen is detected. 6.35 g of the prepared Pb/Pt/C catalyst (ratio Pt/Pb 5/2) is added and the suspension is stirred at 1300 rpm for another 10 minutes under nitrogen. The reaction is started by switching from nitrogen to oxygen (maximum 10% oxygen in the mixture). The reaction is continued without further pH control. The reaction is stopped after 2.5 hours reaction time.
