Procedure

The resulting catalyst precursor was reduced by passing a gaseous stream of geraniol and nerol (65% geraniol/35% nerol; 670 mg/min, 4.3 mmol/min), O2 (73 ml/min, 3.3 mmol/min), and steam (10 ml/min water) through the reactor tube at 360° C. to produce citral in 80% yield (moles of citral produced per mole of nerol/geraniol introduced; determined by capillary weight percent gas chromatograph).
