[0058] The present application also provides a method for preparing a sulfonic acid-based aionic bonchronic surfactant, comprising the steps of:
[0059] 1) In the presence of the first catalyst, the siloxane and the endylideate were performed at 70 to 90 ° C for 4 h ~ 5H first catalytic reaction, the molar ratio of silicone and the endylsate of 1: (1.1 ~ 1.5) )
[0060]
[0061] 2) In an inert atmosphere, the first reactive intermediate is carried out at a sodium hydroxide solution for 4 h to 5 h at 25 to 40 ° C, wherein the molar ratio of the first reaction intermediate and sodium hydroxide is 1: (3 ~ 8), then cool, the pH value of 5 wt% hydrochloride is adjacent to 5, preferably for filtration, washing with anhydrous ethanol, and dried to obtain a second reaction intermediate;
[0062]
[0063] 3) In an inert atmosphere, the second reaction intermediate is mixed with dichloride, and the second catalyst dimethylformamide or tetramethylene group is added, and the second catal...

[0073]
[0074] This example provides a method of preparing a sulfonic acid-based anionic bonchronic surfactant (ethylene-bis (N-ethylsulfonate-ninethylenetrialkoxionamide), specifically comprising the steps of:
[0075] 1) Synthesis of methomethyl trikaroxane acrylate
[0076] 1 mol of ninemethylene trikoxane and 1.2 mol of methacrylate were added to 80 ° C, stirred with stirring, and chloroplatinic acid was added, and the first catalytic reaction of 4 h was added, and the decompression was distilled. Methyl silicate;
[0077] 2) Synthesis of ninemethylene three siloxane propionic acid
[0078] Under nitrogen protection, 1 mol of ninemethylene trikaroxoalkoxide, 4.0 mol of sodium hydroxide and 2000 mL of distilled water were added to the reactor, and the water was adj to 5 after 4 h at room temperature, and there was a lot of hydrochloride. Solid precipitation, filtrate, filter cake was washed with anhydrous ethanol, and then nin...
