Yield:352-87-4 33.9 g

Reaction Conditions:

with 1-methyl-1H-imidazole at 20; for 4 h;

Steps:

1 Production Example 1
15.0 g of 2,2,2-trifluoroethanol and 9.8 g of 1-methylimidazole were placed in a glass reaction vessel, and 10.5 g of methacrylic acid chloride was added dropwise at room temperature and stirred for 4 hours. After the completion of the reaction, the product liquid was 33.9 g, and as a result of analyzing this reaction product solution,The reaction product liquid is methacrylic acid15.8 g of 2,2,2-trifluoroethyl ester as an ionic liquidIt contained 11.1 g of 1-methylimidazole hydrochloride
