A mixture of 94 grams (1.0 mol) of phenol, 5.31 g (0.0500 mol) of 3-mercaptopropionic acid, 10 g of LEWATIT BE ion exchange resin and 1.0 g of 2,6-dimethylnaphthalene (internal standard for liquid chromatography analysis) was heated to about 65° C. in a round bottom flask equipped with a condenser, an internal thermometer and a mechanical stirrer. The solution was held under a static nitrogen atmosphere and stirred at about 65° C. for about 8 hrs. after which the THPE was isolated by precipitation with methylene chloride (4 mL/1 g of reaction mixture). The yield is given in Table III.
