    Abstract: In a process to make dithiodiglycol by oxidation of β-mercaptoethanol with sulfur, an improved product is recovered when a 1-10 mol % excess of β-mercaptoethanol is used and hydrogen sulfide is removed by vacuum or nitrogen sparge. A typical product contains 88.1 mol % (92.0 wt %) dithiodiglycol, 2.3 mol % (2.9 wt %) trithiodiglycol and 9.6 mol % (5.1 wt %) unreacted β-mercaptoethanol. Reaction of this product with 35 to 50 wt % solution hydrogen peroxide reduces residual β-mercaptoethanol to less than 0.02 wt % mercaptan. Residual water of about 3.6 wt % after hydrogen peroxide treatment is reduced to less than 1 wt % by vacuum stripping and/or nitrogen sparge or with a wiped film evaporator.
