| Abstract: |
| The epoxidized natural rubbers(ENRs) with different epoxide numbers(B) were prepared by suitably increasing the reaction temperature and reducing the formic acid and hydrogen peroxide，the equation of reaction kinetics in ENR preparation was derived from the basic reaction equation and the relationship of B to reaction temperature and time，formic acid and hydrogen peroxide level was discussed.The results showed that the reaction in ENR preparation by epoxidizing NR with formic acid peroxide was the first order reaction，and the reaction of NR with hydrogen peroxide was the second order reaction.The resultant reaction rate constant k4 was 1.125×10-4 dm3·(mol·s)-1，activation energy was 82.674 kJ·mol-1；the relationship between B and hydrogen peroxide was linear. |
