Yield: 64%

Reaction Conditions:

with tetra-n-propylammonium bromide;sodium sulfite in water for 20 h;Reflux;Time;

Steps:

2 Example 2 A kind of ion pair chromatography reagent is fourteen method of preparing sodium alkyl sulfonic acid, comprising the following steps:
(1) sulfonated: the cooling return device and mechanical stirring 5000 ml in three-mouth bottle, by adding 378g anhydrous sodium sulfite and 1350 ml water, then adding 542 g 1-polybromide tetradecane and 4.2 g four n-propyl ammonium bromide, heating reflux for 20 hours, to the reaction solution until no delamination clarification. (2) purification of: the pressure under the conditions of 85 °C/20mmHg evaporating the water content in the reaction mixture, and the remaining solid after drying, in a Soxhlet extractor, using 5500 ml anhydrous ethanol extraction, crude 660 g, then using 11000 ml anhydrous ethanol recrystallized, get the pure product after filtering. (3) drying: the purification of the product in the vacuum inside the drying box, to dry the condition 80 °C/100mmHg 3 hours, to obtain the finished product 585 g (yield 64%), content ≥ 99.6%.
