Embodiment 1

[0041] Add 18 g of water and sodium hydroxide (1.1 mol) into a flask equipped with stirring, a thermometer and a reflux condenser, stir well and then add glycine (1.1 mol). The temperature was raised to 60°C, glycidyl stearate (1 mol) was slowly added dropwise, and after 12 hours of reaction, the reaction was stopped. Post-processing method: Pour into acetone, precipitate solid, suction filter while hot, rinse solid twice with acetone, and dry to obtain a new surfactant of sodium stearate glycinate.

Embodiment 2

[0043] Add 30g of water and potassium hydroxide (1.5mol) in the flask equipped with stirring, thermometer and reflux condenser, add valine (1.5mol) after stirring evenly. The temperature was raised to 80° C., and glycidyl caprylate (1 mol) was slowly added dropwise. After 12 hours of reaction, the reaction was stopped. Post-treatment method: Pour into acetone, precipitate solid, suction filter while it is hot, rinse the solid twice with acetone, and dry to obtain a new type of surfactant of potassium caprylate valine.

Embodiment 3

[0045] Add 20g of water and sodium hydroxide (1.2mol) in the flask equipped with stirring, thermometer and reflux condenser, add sarcosine (1.2mol) after stirring evenly. The temperature was raised to 90°C, glycidyl laurate (1 mol) was slowly added, and after 15 hours of reaction, the reaction was stopped. Post-treatment method: Pour into methanol, precipitate solid, suction filter while it is hot, rinse the solid twice with acetone, and dry to obtain a new surfactant of sodium laurate sarcosinate.

Abstract

The invention belongs to a synthesis technology of a surfactant, and relates to a preparation method of a novel amino acid and meglumine surfactant. Specifically, the method comprises the following steps of: sequentially adding glycidyl ester, amino acid or meglumine substances, inorganic alkali and deionized water into a reaction kettle provided with a stirring device, heating to perform a reaction, and cooling to room temperature after the reaction is finished; and pouring reaction liquid into an organic solvent, separating out a solid, carrying out suction filtration while the solid is hot, and drying to obtain a product. According to the preparation method of the novel amino acid and meglumine surfactants,the novel C-N connected amino acid and meglumine surfactants are prepared through one-step reaction of glycidyl ester and amino acid or meglumine, the reaction steps are few, the yield is high, aftertreatment is simple, and good market prospects are achieved.
