| description | The invention relates to the field of isooctyl salicylate, and particularly discloses a preparation method of isooctyl salicylate. The preparation method comprises the following steps: S1, uniformly mixing methyl salicylate, isooctanol and a solid organic base catalyst, and reacting for 15-16 hours under the conditions that the vacuum degree is less than-0.08 MPa and the temperature is 100-120 DEG C to obtain a crude ester-catalyst mixture and methanol gas; s2, filtering the crude ester-catalyst mixture, separating crude ester and a solid organic base catalyst, and recycling the solid organic base catalyst; and S3, carrying out reduced pressure distillation on the crude ester organic layer, and condensing the distilled component to obtain the isooctyl salicylate. The isooctyl salicylate prepared by the preparation method disclosed by the invention has the advantages of higher yield and purity, simple process and lower production cost, and is suitable for large-scale industrial production.
