production method | from benzene and propionyl chloride by condensation, hydrolysis. The benzene and anhydrous aluminum trichloride were put into a glass-lined reaction Pan, cooled to 10 ° C. With stirring, and a mixture of propionyl chloride and anhydrous benzene was added dropwise. After dropping, slowly raise the temperature to 20 °c for 1H. The reaction solution was added to ice water, and the mixture was hydrolyzed by stirring at 30 °c or lower. The oil layer was separated by standing, washed with sodium hydroxide solution, washed with water until neutral, and distilled under reduced pressure to collect a 12-120 ° C. (4.0kPa) fraction, I .e., phenylacetone, with a yield of 85%. |
