실험 절차

Five-hundred grams molten erucic acid were slowly added to a mixture of 679 gms toluene and 723 gms concentrated sulfuric acid while maintaining the temperature below 10° C. Tolyldocosanoic acid (acid value 123) was obtained in 82% yield. Distilled tolyldocosanoic acid (108 gms), 400 mls acetic acid 9.8 gms Co(OAc)2.4H2O and 1.3 gms ZrO(OAc)2 were then heated at 105° C. and 350 psi O2 for six hours during which time the acid value increased from 127 to 207. The selectivity to the desired carboxyphenyldocosanoic acid was 64.4% at a tolyldocosanoic conversion of 53.7%.
