sodium 2-[(2-aminoethyl)amino]ethanesulphonate Chemical Properties,Usage,Production

Chemical Properties

light yellow liquid

Uses

Sodium 2-((2-Aminoethyl)amino)ethanesulfonate is used in the preparation and performance of waterborne polyurethane with ethylenediamine sodium sulfonate as hydrophilic group. Sodium 2-((2-Aminoethyl)amino)ethanesulfonate is also used as crosslinking agent for siloxane coating for transparent plastics.

Synthesis

111-41-1

34730-59-1

The general procedure for the synthesis of 2-[(2-aminoethyl)amino]ethanesulfonic acid sodium salt (50% aqueous solution) from hydroxyethyl ethylenediamine was as follows: 5.0 g of β-hydroxyethyl ethylenediamine (1 mol) was placed in a three-necked flask assembled with a stirrer, a thermometer, a dropping funnel, and an ice-salt bath. Concentrated sulfuric acid was slowly added through the dropping funnel while the reaction temperature was maintained below 10 °C using an ice-salt bath during the dropping process until the sulfuric acid addition was complete. After removing the ice-salt bath, the reaction mixture is heated for vacuum distillation until no anhydrous fraction is distilled out to give the intermediate product ethylenediamine ethanol sulfate. Toluene may be added as a water-carrying agent during this process. After the reaction product is cooled to room temperature, sodium carbonate solution is added dropwise until no more gas is produced. Subsequently, a preheated prepared saturated sodium sulfite solution (151 g solute) is added for the sulfonation reaction. The reaction was refluxed at 100 to 120°C for 30 h. Upon completion of the reaction, partial vacuum distillation was carried out, cooled to 90?95°C, and filtered while hot to remove the sodium sulfate and sodium sulfite crystals to obtain the crude sodium salt of ethylenediamine sulfonate. A higher purity sodium salt of ethylenediamine sulfonate can be obtained by subsequent refining processes such as cooling and crystallization, acidification, recrystallization and purification and salting out, with a combined product yield of 75%. It should be noted that the use of concentrated sulfuric acid in this process has high requirements for equipment and produces pollutant gases such as sulfur dioxide; at the same time, due to the need to recrystallize several times to separate the sodium sulfate, a large amount of acid-containing wastewater will be generated.
