Paragraph 0014-0019, (2018/02/04)
The invention discloses a method for preparing ethylene diamine tetraacetic acid disodium by means of a membrane chemical reactor. The method comprises the steps of 1, material feeding, wherein a certain amount of deionized water is put into the membrane chemical reactor, and then liquid sodium hydroxide and ethylene diamine tetraacetic acid are put into the membrane chemical reactor according to the mass ratio of 2:4 at 95 DEG C by eight batches till the pH value of reaction solution is 5; 2, heat insulation, after materials are fed, heat insulation is conducted on the reaction solution at 90 DEG C for 45 min, and the pH value of reaction solution is controlled to be 5. The preparing process is simple, parallel reaction selectivity and safety are high, three wastes are not generated basically during production, the produced ethylene diamine tetraacetic acid disodium powder is pure white, purity is 99.8% or more, and quality is stable.
