Modification of Salicylic Acid Esterfication Based on Epichlorohydrin

Salicylic acid as an important growth promoter for crops has broad applications in the field of agriculture.Using epichlorohydrin as material,a modified product of salicylic acid was prepared through esterification reaction.The structure of the product was characterized by Fourier transform infrared spectroscopy.The reaction conditions were optimized and the yield of the product was evalued.When the molar ratio of epichlorohydrin and salicylic acid was 1.5,the reaction solvent was 1,2-dichloroethane,the reaction temperature was 50 ℃,the maximum yield was 87.5%.This research will provide a new method for increasing the water-solubility of salicylic acid,and promote the application and development of salicylic acid in the field of agriculture.
