orginal:
20 to 30 grams phenyl acetic acid are boiled with a large excess of calcium carbonate in a 1l of water. The hot, filtered solution is then evaporated to dryness upon a steam-bath, and the residue of calcium phenyl acetate dried at 12o° to 13o° for several hours. At this temperature the salt melts, and when cooled presents a vitreous appearance.
