Reaction Steps
The HBr catalyzed oxidation of diethyl disulfide was carried out at 110° C. With the same concentration as above except for a concentration of 0.0356 M HBr catalyst, the oxidation was complete in 33/4 hours. The yield as the crude sodium sulfonate salt after neutralization was 82% with correction for Na2SO4. The oxidation of diethyl disulfide produced more H2SO4 than that of DMDS. The yields of H2SO4 were 8% with I2 catalysis and 0.6% with HBr catalysis.
