Embodiment 1
[0023] 112.2 g of 1-hexadecene was added to a 500 ml four-necked round-bottom flask, stirred with a magnetic stirrer, 69.0 g of salicylic acid was slowly added, and then 13.8 g of benzenesulfonic acid was added. Nitrogen gas was introduced, the reaction temperature was 120° C., and the reaction time was 7 hours. After the reaction is finished, water is added to wash to remove the catalyst, and after standing to separate layers to remove water, the product alkyl salicylic acid is obtained. The conversion rate of olefin reaction was 89.6%.
Embodiment 2
[0025] 126.2 g of 1-octadecene was added to a 500 ml four-neck round-bottom flask, stirred with a magnetic stirrer, 69.0 g of salicylic acid was slowly added, and then 13.8 g of benzenesulfonic acid was added. Nitrogen gas was introduced, the reaction temperature was 130° C., and the reaction time was 7 hours. After the reaction is finished, water is added to wash to remove the catalyst, and after standing to separate layers to remove water, the product alkyl salicylic acid is obtained. The conversion rate of olefin reaction was 76.2%.
Embodiment 3
[0027] Add 117.6 g of C16C18 alkenes to a 500 ml four-neck round bottom flask, stir with a magnetic stirrer, slowly add 69.0 g of salicylic acid, and then add 13.8 g of benzenesulfonic acid. Nitrogen gas was introduced, the reaction temperature was 130° C., and the reaction time was 7 hours. After the reaction is finished, water is added to wash to remove the catalyst, and after standing to separate layers to remove water, the product alkyl salicylic acid is obtained. The conversion rate of olefin reaction was 83.7%.
