  • Publication number: 20240092726
    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.

  • Patent number: 10078765
    Abstract: The invention provides multiple methods and devices for processing a stolen terminal. Therein, a method for processing a stolen terminal comprises: receiving a state modification message from a sending party, wherein the state modification message carries the current state of the terminal; and in a case where the state modification message is legal, forwarding the state modification message to a server, so that the server modifies the state information of the terminal stored in the server to be the current state according to the state modification message. By employing embodiments of the invention, the state information of a terminal can be modified, which solves the problem in the prior art that other identification cannot be provided to indicate whether the terminal is stolen or not, and can achieve the beneficial effects of increasing the probability of recovering a stolen terminal and effectively curbing the stealing acts.
