5-methyl 5-nonyl methacrylate and preparation method and application thereof

Abstract

The invention is suitable for the technical field of materials, and provides 5-methyl 5-nonyl methacrylate and a preparation method and application thereof. An intermediate 5-methyl 5-nonanol is obtained by reacting 5-nonanone with lithium particles, and the 5-methyl 5-nonanol is reacted with methacrylic anhydride or methacryloyl chloride to generate 5-methyl 5-nonyl methacrylate. The synthesis process is simple, synthesis is carried out at room temperature, reaction conditions are mild, control is facilitated, side reactions are few, separation is easy to implement, and the purity and yield are high. The prepared 5-methyl 5-nonyl methacrylate has a long chain structure, has good film forming performance, has excellent photosensitive performance, high photosensitive speed, high optical sensitivity and good flexibility, and can be applied to semiconductor materials and various optical materials.
