| Abstract: | Hydrolyzing ammondysis chloroacetic acid to produce glycolic acid is a parallel and a competitive side reaction in synthesis glycine. Through experimented results and kinetics analysis, the second order parallel reaction is derived, its rate constant under certain temperature and activation energy can be calculated,the Arrhenius experience formula can be obtained. The influence of temperature on the reaction is discussed, it is pointed out the temperature of the synthesis glycine could not be high. |
