Versuchsvorschrift

Isodecyl alcohol (791.4 grams; 5.-0 mol), benzoic acid (622.8 grams; 5.1 mol), zirconium carbonate (3.3 grams) and toluene (75 ml) were placed into a three-necked, round bottom flask equipped with stirrer, thermometer, 10" Vigeraux column, water trap and condenser. The reaction temperature was 184° C., washed first with water (25 mls) at 90°-95° C. for 30 minutes, then with sodium carbonate (15%) at 90°-95° C. for 30 minutes and twice with water (300 ml) at 90° C. for five minutes. After being washed, the product was dried at 125° C. and filtered to yield the desired product (1254.6 grams; 95.6% yield). It assayed 99.5% with the following properties:
