Studies on the rates of mutarotation of the benzyl-N-carbobenzoxy-D-glucosaminides
The independent interconversion of alpha-N-carbobenzoxy-D-glucosaminide to the beta- form, and vice versa, suggests that the proper treatment of the rate data must involve a system of opposing reactions. It is evident from the data cited in the preceding chapter that such opposing rates must necessarily involve the HCl which is included in the reaction mixture. Thus, as the first approach to the analyzed data, it is reasonable to suppose that the rate law for opposing second-order rates will apply. However, it is also apparent from the data that the concentration of HCl used in all this work exceeds the glycoside concentration by a factor of about one hundred times. Therefore, the postulated system of opposing second order processes may be reduced to a system of opposing [pseudo-first-order processes. Such a system can be formulate as follows: [see PDF]
