Reaction Steps

A treatment for canker sores was formulated. A solution of phenolsulfonic acid was prepared as described in Example 1, except that the weight of available stock liquefied phenol USP was calculated and prepared for 2.4 moles of phenol. The amount of available stock sulfuric acid NF that contained 5.26 moles was calculated. The weight of sulfuric acid NF was 515.90 grams. The 5.26 moles of sulfuric acid NF was treated as described in Example 1. A quantity of 400 mL of Liquified Phenol USP was added to a 600 mL beaker. A quantity of 2.4 moles of phenol as Liquefied Phenol USP was added to a 1 L Corning Pyrex No. 1395 bottle using the Mettler PS-5002-S balance.
