The invention discloses a novel path for synthesizing 2-hydroxy-4-methylbenzenesulfonic acid. The method is characterized by comprising the steps of taking a compound in a general formula I as a raw material, generating a compound of a general formula II through sulfonation reaction, and causing the compound of the general formula II to undergo catalytic hydrogenation reaction to obtain the target product 2-hydroxy-4-methylbenzenesulfonic acid. The total yield can reach 74%. According to the process path, the raw materials are low in cost and easy to obtain, and the path is simple to operate, short in reaction time and suitable for industrial production.
