실험 절차

To 2.83 g of the crude reaction solution obtained was added 0.11 g of methanol, followed by heating at 60° C. for 4 hours. Then, it was found out by gas chromatography analysis that the conversion of the 1,1,1-trichloro-2-methyl-2-propanol was 86.0% and the yield of methyl 2-chloro-2-methylpropanoate was 10.2%. As to other products, it was obtained methyl methacrylate in a 0.2% yield, methacrylic acid in a 8.7% yield, (1,1,1-trichloro-2-methyl-2-propyl) methacrylate in a 13.1% yield, and (1,1,1-trichloro-2-methyl-2-propyl) 2-chloro-2-methylpropanoate in a 22.8% yield.
