Abstract

The invention discloses an amphoteric ionic Gemini surfactant shown in a structural general formula (I), which is characterized in that R is alkyl of CnH2n +1, and n is equal to the integer of 418. The surfactant takes fatty acid as a raw material, and the fatty acid is reduced to obtain alpha-bromo fatty alcohol through alpha-bromo; and the alpha-bromo fatty alcoho is reacted with propane sultone to obtain alpha-bromo alkoxy propane sulfate, and finally, the alpha-bromo alkoxy propane sulfate is reacted with tetramethylethylenediamine to obtain the amphoteric ionic Gemini surfactant. The surfactant has higher surface activity, excellent synergetic property, excellent soft smoothness and antistatic property for fabrics, good wetting and foaming properties, and good absorption property for the surface of the charged material, and does not produce a water-repellent thin layer.

Description

technical field The invention provides a zwitterionic Gemini surfactant and a synthesis method thereof, belonging to the technical field of surfactant preparation. Background technique Different from ordinary surfactant structure, zwitterionic Gemini surfactant has two cationic groups and two anionic groups, and its special molecular structure makes it have many special properties: (1) It has a relatively low CMC value, and its performance is more efficient than ordinary surfactants; (2) The zwitterionic Gemini surfactant has an isoelectric point and has the surface activity of two ionic surfactants; (3) Strong compounding performance, can be compounded with almost any other type of surfactant, and most zwitterionic surfactants have good synergistic effect; (4) Very low irritation, less irritating to human skin and eyes, and rarely interacts with fragrance; (5) Good wettability and foamability, good adsorption to the surface of charged substances, without forming a h...
