| titleOfInvention | A kind of secondary amide sulfonic acid type surfactant and its preparation method and application |
| abstract | The invention relates to the technical field of surfactants, and specifically provides a secondary amide sulfonic acid type surfactant and a preparation method and application thereof. The general molecular structure of the secondary amide sulfonic acid surfactant is: Wherein, R is one of methyl, ethyl, and hydroxyethyl. The preparation method includes the following steps: 1) preparing a reaction intermediate I, the structural formula of the reaction intermediate I is C 18 H 37 NH(CH 2 ) 3 NHCH 2 CH 2 CONHC(CH 3 ) 2 CH 2 SO 3 H; 2 ) Preparation of intermediate II, the general structural formula of the reaction intermediate II is Wherein, R is one of methyl group, ethyl group and hydroxyethyl group; 3) The reaction intermediate II is added dropwise to the reaction intermediate I, mixed and reacted to obtain the secondary amide sulfonic acid type surfactant. Solve the problems in the prior art that the surfactant still has poor foam suppressing performance and emulsifying performance, complicated preparation method, mainly high reaction temperature and complicated process steps. |
