반응 단계

An analysis of the crude reaction solution by gas chromatography revealed that the conversion of 1,1,1-trichloro-2-methyl-2-propanol was 67.7% and the yield of methyl 2-chloro-2-methylpropanoate was 36.5%. As to other products, it was obtained (1,1,1-trichloro-2-methyl-2-propyl) methacrylate in a 10.5% yield, and (1,1,1-trichloro-2-methyl-2-propyl) 2-chloro-2-methylpropanoate in a 13.5% yield. The crude reaction solution obtained was distilled under a reduced pressure, thereby obtaining methyl 2-chloro-2-methylpropanoate at a purity of 85%.
