| Abstract: | The optimum conditions were studied under which chloroacetic acid was aminolysed to synthesize HClsalt of iminodiacetic acid in the presence of calcium hydroxide. The analysis method of the content of product was also proposed. The mole ratio of chloroacetic acid to ammonia, calcium hydroxide and hydrochlorid was 1.00.91.02.4. The temperatures for the operations relating to adding materials, reacting, acidifying and crystalizing were 2030 , (452) , 6580 and (02) , respectively. The time relating to these operations was 4 h,6 h, 0.51 h and 8 h, respectively. The mass fractions of ammonia and chloroacetic acid were 25% and 80%, respectively. The coefficient of variation of the analysis method was 0.034%, and the recovery rate of the addition method was 99.72%. |
