Abstract

The invention relates to a method for preparing a gydroxysulfobetaine amphoteric surface active agent including a polyether chain segment, belonging to the technical field of preparation of surface active agents. The gydroxysulfobetaine amphoteric surface active agent including the polyether chain segment is prepared by taking fatty amine polyoxyethylene ether and 3-chlorine-2-hydroxyl propane sodium sulfonate as raw materials. The gydroxysulfobetaine amphoteric surface active agent including the polyether chain segment is shown as a chemical structural formula in the specification. According to the gydroxysulfobetaine amphoteric surface active agent including the polyether chain segment synthesized by using the method disclosed by the invention, three hydrophilic groups consisting of polyoxyethenyl, quaternary ammonium salt and sulfonyl and hydrophobic alkyl are included; the gydroxysulfobetaine amphoteric surface active agent including the polyether chain segment has the two good surface activities of the non-ionic and amphoteric surface active agent; in addition, besides the good performance of the traditional gydroxysulfobetaine amphoteric surface active agent, the performances, such as water solubility, detergency, emulsifiability, dispersibility, solubilising power and the like, are improved obviously.

Description

technical field [0001] The invention relates to a sulfobetaine amphoteric surfactant, in particular to a preparation method of a hydroxysultaine amphoteric surfactant containing a polyether segment, and belongs to the technical field of surfactant preparation. Background technique [0002] Among surfactants, amphoteric surfactants have excellent resistance to hard water and electrolytes due to their structure containing both anionic and cationic groups; low toxicity and easy biodegradation; low toxicity to skin and eyes Irritant; good compatibility. At the same time, they also have the characteristics of anionic and cationic surfactants, such as good emulsification, dispersibility, antistatic and soft and smooth properties; certain bactericidal and mildew inhibiting properties. In short, it is a class of surfactants with excellent performance, so the annual growth rate of amphoteric surfactants at home and abroad is far greater than that of other types of surfactants in rec...
