Abstract: The present disclosure discloses a method for synthesizing quinolones intermediates by a continuous flow reaction. Specifically, according to the method, a microchannel reactor is used, which improves the selectivity and conversion rate of the reaction, and the conversion rate of compound ii is increased to more than 95% and the yield is increased to more than 85%; avoids the use of a solvent such as methanol, and methyl tert-butyl ether, etc., in the intermittent reaction process, which simplifies the post-processing method, shortens the overall operation time from about 24 hours to a few minutes, greatly improving the production efficiency, and realizing the continuity and automation of the whole process; and thus makes the product have high purity and high yield, which is suitable for industrial production.

Abstract: A plug-in electric ceramic heating plate and an electric stove provided with the heating plate are disclosed. The plug-in electric ceramic heating plate comprises a plate body and a plate component, and the electric stove provided with the heating plate comprises an electric socket matched with an electric plug on the plug-in electric ceramic heating plate. The plate body includes a plate shell, a temperature controller, a microcrystal glass plate, the electric plug, an electric plug press plate, a plug adapter and a bottom cover plate. The electric plug is connected with the plate component through the plug adapter. The plate has notches formed on its circumference. A convex edge corresponding to the shape of the notch on the circumference of the plate is arranged in the plate shell.
