High-quality alpha-olefin sulfonate production process

The invention belongs to the technical field of fine chemical engineering, and aims to provide a high-quality alpha-olefin sulfonate production process which is low in alpha-olefin residue, high in active matter content and shallow in color. The process can be simply implemented on the existing device for producing alpha-olefin sulfonate, and the existing sulfonation devices cannot be changed. Thetechnical scheme includes that the high-quality alpha-olefin sulfonate production process includes the steps: 1) dissolving an appropriate quantity of sulfonation catalysts in alpha-olefin in advance; 2) performing sulfonation on the alpha-olefin with the dissolved sulfonation catalysts in advance on an existing gas-phase SO3 membrane-type sulfonation device according to existing sulfonation production processes of the alpha-olefin sulfonate; 3) performing acid ester cooling to reach the temperature of 30-35 DEG C after sulfonation, and producing the alpha-olefin sulfonate according to an existing aging, neutralizati
