text: Inspection of the data in these examples shows that by using sulphuric acid as the preferred acidifying agent, and relatively small amounts of diluting water in the acidification step such as in Example 1, namely a ratio of 4 parts ethylene glycol to 1 part water, that in the subsequent steps, a higher yield of ethylene glycol is recovered in the product fraction, and this ethylene glycol is of higher purity'as evidenced by its lighter color, narrower boiling range, lower residual acidity and corrosion index than the ethylene glycol recovered by the use of higher ratios of water to ethylene glycol as exemplified by the 1:1 ethylene glycol-water ratio of Example 2, and the still higher 1:2,ethylene glycol-water dilution of Example 3.
