  • 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.

  • Publication number: 20190155851
    Abstract: This application discloses an information filtering method and an information processing apparatus. Shared information that is shared by a user account of an online service is obtained. A credibility reference rating associated with the user account is obtained. The credibility reference rating indicates account credibility of the user account. Whether the shared information satisfies a filtering condition is determined based on the credibility reference rating. Further, the shared information is filtered when the shared information is determined to satisfy the filtering condition.

  • Publication number: 20060166955
    Abstract: The present invention relates to a clean process for the degradation of steroidal sapogenin to produce 16-dehydropregnenolone and its analogs. The pure or the crude pseudo steroidal sapogenin, derived from steroidal sapogenin, dissolved in organic solvent, reacts with hydrogen peroxide with or without metal compound and acid as catalyst, and the crude products directly go through elimination and hydrolization in the presence of base to give 16-Dehydropregnenolone or its analog, accompanied with the other product 4R(or S)-methyl-5-hydroxy-pentate, which is converted to 4R(or S)-methyl-?-pentyl lactone after acidification and extraction from the water layer. This technology improved the utilizing degree of steroidal sapogenin, improved the yield, and cleared up the chromium pollution in the former technique. In a word, the method disclosed in this invention is more suitable for manufacture.
