Polarographie der Tetrosen und die Anwendung der Polarographie beim Studium der Spaltung von 1.1‐Bisalkylsulfonyl‐pentose‐enen‐(1)

Abstract: P m ZUMAN und HELMUT ZINNWPolarographie der Tetrosen und die Anwendung der Polarographie beim Studium der Spaltung von 1.1-Bisalkylsulfonyl-pentose-enen-( 1)Erythrose wird in einer zweielektronigen Stufe an der Quecksilbertropfelektrode reduziert. Die pH-Abh;ingigkeit der Stufenhbhe wird durch pH-verhderliche Reaktionsgeschwindigkeit der Dehydratation der hydratisierten Form der Erythrose, welchein W r i g e n m u n g e n Uberwiegt, erklm. Die polarographischen Stufen der Tetrosen dicnten zum Verfolgen der Abb… Show more

“…Kuta [616] observed an increased reduction rate for oxalic acid esters on increasing ionic strength of the solution, particularly if polyvalent cations were introduced into the solution. A similar effect of cations on the reduction of tetrose was described by Zuman and Zinner [214].…”

“…The wave height on the polarographic curves of erythrose solutions is limited by the rate of dehydration of the molecules [214]. It increases with increasing pH attaining a maximum height (at pH 10-12) that nearly corresponds to the diffusion current with n = 2.…”

“…The method has followed the conversion of carbohydrates of oak wood in brandy wine storage (193), analyzed for glucose and lactose in the control of penicillin production (205), followed the acid hydrolysis of raffinose, sucrose, melezitose (1034), the hydrolysis of 1,1 -bis methanesulfonylderythropentose-ene-1 to tetroses (1113), and studied the behavior of fructose in the presence and absence of borate (937).…”
