The Action of Sodium Hydroxide on Cellulose

were not obtained for the purpose under discussion, but it will be noted in every set of data that the amount taken up by cliange-in-titer is lower than the total amount. It will further be noted that, wherever sufficient data are at hand, a flat portion of the curve is found, and that this portion occurs at 0.3 mol of NnOII per mol (162 g.) of cellulose. It is evident that the amount of water taken up is not so small a quantity that it can be neglected, ;ix is done in the change-in-titer method. Examination of these curves should show that those maintaining the formation of the chemical compound « ’&dquo;If&dquo;,On)2.NaOH in mass have not
