NOVELTY - Producing isooctyl salicylate comprises e.g. adding salicylic acid and isooctanol into a reaction kettle, adding water carrying agent and catalyst, stirring, raising temperature, refluxing and reacting, separating water, cooling, filtering, recovering catalyst and reusing, adjusting the filter liquor pH, separating water, washing organic phase with water to neutral, carrying out atmospheric distillation and recovering solvent, adding crude product into rectifying kettle, carrying out vacuum extraction and rectifying in a rectifying device with a reflux condenser.    USE - The method is useful for producing isooctyl salicylate (claimed).    ADVANTAGE - The method can recycle esterified catalyst after synthesis, and unreacted salicylic acid, which can be used in the next batch of synthesis, thus saving raw material and its cost; is simple and easy to operate; and is suitable for industrialization.    DETAILED DESCRIPTION - Producing isooctyl salicylate comprises (i) esterifying: adding salicylic acid and isooctanol according to mol ratio of 1:1.2:1.5 into a reaction kettle, then adding 1-1.5 times of water carrying agent and 0.1-0.2 times of catalyst, stirring, raising temperature, refluxing and reacting, separating water, GC detecting residual salicylic acid to less than 0.05%, stopping reaction, cooling, filtering, recovering catalyst and reusing, adjusting the filter liquor pH to 8.5-9.5, separating water, at last, washing obtained organic phase with water to neutral, carrying out atmospheric distillation and recovering solvent, where the residue is mainly composed of isooctyl salicylate crude product, and repeating solvent recovery process, and (ii) purifying crude product: adding obtained crude product into rectifying kettle, carrying out vacuum extraction and rectifying in a rectifying device with a reflux condenser, where the vacuum degree is 150-200 Pa, distilling isooctanol, iso-octyl ether and iso-octyl salicylate with purity of less than 99.5%, finally collecting purity greater than or equal to 99.5%, iso-octyl ether residue is less than 0.01% of fraction to obtain the product.
