Descripción: In a Ph.D. Thesis submitted in 1946 from this Laboratory, Tasker prepared in pure form the series of the monoethyl ethers of the polyethylene glycols, R(OCH2CH2)n0H, where n was 1, 2 or 3. The tendency of several of these compounds to form peroxides when exposed to light and air was noted, the esters made with p-toluenesulfonyl chloride (tosyl chloride) and pyridine were prepared, and the replacement by iodine atoms of the tosyloxy groups in the products was studied. Tasker then applied the tosylation-iodination technique to a commercial hydroxyethyl ether of cellulose, but his results made it clear that side-reactions of an unexpected nature were occurring. In the light of the knowledge gained from his studies in the polyethylene oxide series, Tasker put forward suggestions concerning the possible nature of the side-reactions. These suggestions, however, were only tentative, because at that time the literature contained no reference to the existence of an hydroxyethyl derivative of a simple sugar, the chemical behavior of which would serve as a model for the probable behavior of an hydroxyethylcellulose.
