The amide hydrolysis rate constants are about one order of magnitude higher than the extrapolated results from other investigators, but the reaction rate increased proportionally with hydroxide ion concentration, suggesting that an alkaline hydrolysis mechanism is also appropriate. These data establish the ...
esterification, ester hydrolysisU.v. scanning experiments indicate the formation of diacylamine intermediates in the alkaline reaction of O-4-nitrobenzoyl- and O-benzoyl-N-nitrophenylglycolamide. The product of these reactions includes the benzanilide derived from a 1→4 migration of the anilino-...
steps involved, and a kind of conversion limit exists when hydrolysis is about 60% complete.Theoretical calculations based on the assumption that the reactivity of each amide group depends upon whether zero, one, or two of its nearest neighbors have reacted were compared with the experimental ...
Alkaline hydrolysis allows the partial separation of the cellulose fibres from the cell wall [55, 62, 112]. These treatments are usually made using diluted solutions of NaOH (1–10%) at low or high temperatures and of concentrated NaOH solutions at low temperatures. NH4OH and anhydrous NH3 (...

This invention relates to an improved process for the production of aliphatic and/or aromatic polyamines containing urethane and/or urea and/or biuret and/or isocyanurate groups and, preferably, also alkylene ether, carbonate and/or acetal groups by the alkaline hydrolysis of NCO-preadducts ...
n is 0, or a positive number up to 99 which may be regarded as an index of the degree of hydrolysis of m + n amide groups originally present; m plus n is equal to 100; and Z is a number from about 0.1 to 30, where Z times 100 is equal to the number of mer units between ...
