Synthesis method of ultraviolet absorber UVA Plus

The invention discloses a synthesis method of an ultraviolet absorber UVA Plus. The method comprises the following steps: step 1, carrying out esterification reaction on phthalic anhydride and n-hexanol to obtain an intermediate monohexyl phthalate without other solvents, enabling the yield to reach over 99%, and enabling the intermediate to be directly subjected to the next step of reaction without refining; step 2, performing an acylation reaction on 3-hydroxy-N, N-diethylaniline and the intermediate monohexyl phthalate under the catalysis of a composite catalyst to prepare an ultraviolet absorber UVA Plus product, enabling the yield to be over 90%. The synthesis method has the advantages of easily available raw materials, easy refining and purification of the product, high yield, low production cost, and suitableness for industrial production.
