PROCEDURE

实验过程

A 1-liter flask was charged with 43.9 g (0.51 mol) of 3-penten-2-ol, 51.6 g (0.51 mol) of triethylamine and 300 ml of dichloromethane, and the mixture was cooled down to 0° C. While stirring the mixture at 0° C., 52.3 g (0.50 mol) of methacryloyl chloride were added dropwise over 1 hour, and the mixture was stirred additionally for 5 hours at room temperature. Solids were separated by filtration from the resultant reaction mixture, and the filtrate was washed 3 times with water and then distilled in the presence of 5 g of p-methoxyphenol to obtain 42.4 g of 1-methyl-2-butenyl methacrylate.
