실험 절차

To a one gallon autoclave reactor is charged 420 g (2.8 mol) of 4'-hydroxyphenylpropiophenone, 116.5 g (3.6 mol) of sulfur, 84 g (1.4 mol) of acetic acid and 189 g (4.2 mol) of dimethylamine. The procedure described in Example 1 is followed and 4'-hydroxyphenylacetic acid product containing less than 100 ppm of total sulfur is obtained.
