High-purity sodium ethylenediamine ethyl sulfonate synthesis method

The invention discloses a high-purity sodium ethylenediamine ethyl sulfonate synthesis method which includes the steps: 1 slowly dropwise adding sodium vinyl sulfonate solution into ethylenediamine under the condition of room temperature and stirring, increasing temperature to perform reflux for 3.5-4.5 hours under the condition of stirring after dropwise adding, and cooling the solution to obtainmixed solution containing sodium ethylenediamine ethyl sulfonate; 2 enabling the mixed solution to pass a strong acid type cation exchange resin adsorption column for adsorbing unreacted ethylenediamine and sodium ethylenediamine ethyl sulfonate, and performing elution with deionized water to remove impurities; 3 performing elution with alkali solution, swapping out the adsorbed ethylenediamine and sodium ethylenediamine ethyl sulfonate and collecting liquid flowing out of the strong acid type cation exchange resin adsorption column to obtain collected liquid; 4 performing decompression concentration on the collected liquid and removing diethylamine to obtain high-purity sodium ethylenediamine ethyl sulfonate. The method is simple, safe and convenient to operate, and the synthesized sodium ethylenediamine ethyl sulfonate is high in purity.

Method for preparing ethylenediamine esilate

The invention relates to a method for preparing ethylenediamine esilate. The method comprises the steps that glycolonitrile and taurine salt serve as raw materials, or glycolonitrile, taurine and alkali metal hydroxide serve as raw materials, and cyanoethyl taurine salt is obtained through a dehydration condensation reaction; then, under the action of a hydrogenation catalyst, an ethylenediamine esilate hydrogenation solution is obtained through hydrogenation; a solvent is removed, and then the product ethylenediamine esilate is obtained. According to the catalyst, aluminum oxide and/or silicon oxide serve/serves as a carrier, and NiO, CoO, MoO3, MnO2 and Tc2O7 serve as active components. According to the method, ethylenediamine esilate can be obtained with a high conversion rate and high selectivity as long as light components such as the solvent in the hydrogenation solution are removed, the method is environmentally friendly in process, economical, safe and high in product yield, and has the industrialization amplification prospects, and purification is easy.
