Abstract
HUT045474 Chromium is eliminated as chromium phosphate from a mother liquor obtd. during chromium trioxide oxidation of iso-eugenol-methyl-ether producing 3,4,3',4':tetra-methoxy-6 (alpha-acetyl-propyl)- benzo-phenone. Sources of phosphate may be: phosphoric acid, tri-sodium-phosphate or phosphate fertilizer, pref. di:hydrogen-ammonium phosphate.
