The present invention discloses a method for synthesizing sodium allyl sulfonate, comprising the following steps: adding a phase transfer catalyst and an inhibitor to a sodium metabisulfite solution, stirring and mixing uniformly to obtain a sodium metabisulfite mixture, and simultaneously introducing the sodium metabisulfite mixture, a sodium hydroxide solution, and allyl chloride into a reactor for reaction to obtain the target product. The synthetic method of the present invention changes the addition order of the raw materials, so that the raw materials to be involved in the reaction enter the reactor at the same time for reaction, and adds a phase transfer catalyst and an inhibitor, which greatly reduces the occurrence of side reactions, improves the selectivity and conversion rate of the reaction, and thereby improves the yield of the product; Compared with the conventional method, the method of the present invention does not need to undergo dehydration, activated carbon decolorization, impurity removal and other steps, and the subsequent treatment steps are simple, which saves production cost, improves production efficiency, and is more suitable for industrialized production.
