In this work, to find out the best conditions, several experiments carried out. So, the highest yield was obtained at (30±3) °C, by gradual addition of sodium monochloro acetate to methylamine solution. The total reaction time is 6 hours. Based on data, and the plots of kinetics of the reaction, a second-order reaction equation was suggested for this synthesis reaction. The rate constant (?), and the regression coefficient (R2) were found as 0.0085 and 0.0934, respectively, which were in the best agreement with second-order reactions. According to the results, these data were applied for scale up laboratory to pilot phase. In addition, an industrial plant was suggested and designed.
