Study On The Reaction Kinetics Of Basic Hydrolysis Of Poly (N-vinylformamide)

To apply basic hydrolysis of polyvinylformamide(PNVF) to productive practice, the kinetics of the reaction was studied, before which the stoichiometric ratio of PNVF and sodium hydroxide being 2:1 had been determined and that the regularity of the reaction had been discussed. There were some conclusions can be drawed from the results: a) the rate equation was of first order with respect to both PNVF concentration and sodium hydroxide concentration; b) the absolute instead of the relative concentration of NaOH is one of the important factors which contribute to the rate constant; c) as the concentration of NaOH steady grows, the rate constant arises in a form like a fold line, that is the rate constant is approximately equal at the certain range of NaOH concentration but ascends greatly out of the scope; d) increasing the concentration of NaOH will decrease the activation energy of the reaction.
