Abstract
The kinetics of hydrogenation of acrylonitrile butadiene rubber (NBR) latex by the action of diimide generated by hydrazine hydrate and hydrogen peroxide in the presence of copper sulfate at low temperature was studied by calculating the initial reaction rate constants. Altering reaction parameters of different reactant dosages such as carbon-carbon double bonds, hydrazine hydrate, hydrogen peroxide, and copper sulfate can be designed to calculate the initial reaction rate constant in a hydrazine hydrate/hydrogen peroxide/copper sulfate reaction system. The method of initial reaction rate constants gives rate constant and reaction order in the hydrogenation reaction of NBR latex calculated from the hydrogenation kinetic data. Based on these kinetic values, the kinetic equation of hydrogenation of NBR latex in this catalytic system at the temperature ranged from 5 to 65 °C and the hydrogenated reaction activation energy were studied in this paper.
