The application discloses a method for constructing a cycloalkene-quinolinone axial chiral compound through a Heck reaction. The method uses a quinolinone compound containing central chirality as a substrate, uses palladium acetate (Pd(OAc)2) and 4,5-bisdiphenylphosphine-9,9-dimethylxanthene (Xantphos) as a catalyst, uses silver phosphate (Ag3PO4) as an alkali, and uses toluene as a solvent to prepare a cycloalkene-quinolinone axial chiral compound. The compound can be reacted with diisobutylaluminum hydride to realize conversion of a functional group. The method has mild reaction conditions, raw materials are easy to obtain, the product has excellent enantioselectivity, and has excellent yield, and thus provides a new method for synthesizing a cycloalkene-quinolinone axial chiral compound.

This invention discloses a low-temperature, high-speed blow molding method for polylactic acid (PLA) drainage bags, relating to the field of polymer materials technology. The method first involves blending PLA with plasticizers and lubricants, melting and granulating the mixture at a specific low-temperature window, and then blow molding it to obtain a substrate. Subsequently, the substrate is pretreated with a silver ion solution and then subjected to in-situ oxidative polymerization with a dispersion containing functionalized pyrrole derivative monomers and silver phosphate microcapsules loaded with perfluorinated monomers, constructing a composite functional coating on the substrate surface. This invention effectively inhibits the thermal degradation of PLA by strictly controlling the low-temperature process parameters of blow molding, ensuring the safety of the substrate; simultaneously, by embedding microcapsules into the coating through in-situ polymerization, it achieves a synergistic effect of antibacterial and hydrophobic functions.
