The application discloses a method for intensifying a Passerini reaction based on a thin liquid film microreactor, and belongs to the technical field of process intensification of the Passerini reaction. In the method, a gas pipeline at an inlet section of the microreactor is extended into a pipeline of the microreactor, so that a uniform ultra-thin liquid film is formed on the inner wall of the pipeline, and alpha-acyloxyformamide can be synthesized efficiently and rapidly, and a pure product can be obtained by rotary evaporation. The method combines the advantages of the past methods, meets the requirements of high efficiency, rapidness, low cost and green chemistry, and can synthesize the product very simply and rapidly, thereby providing good experimental conditions for development of new molecules. Meanwhile, a continuous flow chemistry platform is built, thereby laying a foundation for subsequent industrial application.

This invention discloses a digestion apparatus for determining the content of polyisoprene, comprising a steam generating flask, with a conduit connected to the top of the steam generating flask, and a Claisen inductor connected to the end of the conduit away from the steam generating flask. This digestion apparatus provides a reaction site through the steam generating flask, generating stable steam, which is then provided with a uniform heat source via a heating seat to accelerate sample digestion and prevent localized overheating. The steam is then introduced into the Claisen inductor via the conduit. The Claisen inductor enables multifunctional connections, preventing sample loss, improving reaction efficiency, providing safety protection, preventing harmful gas leakage, improving reaction control precision, and ensuring optimal experimental conditions. The digestion flask provides a sealed, high-temperature and high-pressure resistant reaction environment, promoting the complete decomposition of organic matter in the sample and ensuring reaction uniformity and safety.
