Preparation method of cyanoacrylate ultraviolet light absorber

The invention provides a preparation method of a cyanoacrylate ultraviolet light absorber. Benzophenone compounds represented by general formula I with cyanoacetate under a weakly alkaline condition by using activated carbon grafted acidic ionic liquid as a catalyst to generate a compound represented by general formula II. The preparation method of the cyanoacrylate ultraviolet light absorber adopts the activated carbon grafted acidic ionic liquid catalyst to replace acetic acid, so that the preparation method has the advantages of easiness in recycling of the catalyst, high product yield, fewthree wastes, and convenience in post-treatment, and is an economical, practical and environment-friendly technology.
