Versuchsvorschrift

To a mixture of 1.00 g of methacrylic acid and 0.836 g of ethyl vinyl ether was added 2 mg of p-toluenesulfonic acid monohydrate, and a reaction was allowed at room temperature for 1 hour. The conversion ratio of methacrylic acid was 82%, with the conversion ratio of ethyl vinyl ether of 94%. Accordingly, 1-ethoxyethyl methacrylate was obtained with the reaction yield of 80% and the selection ratio to ethyl vinyl ether of 85%, and a polymer of ethyl vinyl ether was produced.
