摘要： 针对传统含尾气吸收实验装置在拆卸过程中普遍存在的残余尾气泄漏问题，本研究基于压力平衡原理设计了新型实验发生装置，可在免于拆除装置造成尾气泄漏的前提下取得有效产物，去除反应生成的有害气体产物，规避了在拆卸装置时可能发生的残余尾气泄漏风险。在介绍装置的设计思路、使用方法及操作步骤后，本文以本科生化学合成实验——二苯乙二酮的制备为例，通过实际实验对比，新型实验发生装置相比传统实验装置，在保证实验效果和效率的同时，其在实验结束拆除装置过程中的二氧化氮泄漏量大幅度减少，有助于减少尾气对实验操作者的危害，减少环境污染，显著提升了实验室实验教学的安全性和环保性，进一步促进了化学实验教学中环保理念的渗透与实践。

Abstract: Residual gas leakage is a common issue during the disassembly of traditional exhaust gas absorption experimental devices. This study designs a novel reactor based on the principle of pressure equilibrium, allowing for the effective production of materials while preventing the leakage of harmful gases. After introducing the design principles and operational procedures of the reactor, we compare the performance of the traditional and new reactors in an undergraduate chemistry laboratory course. The new reactor not only ensures experimental results and efficiency but also significantly reduces residual gas leakage during device disassembly. This advancement minimizes the exposure of laboratory operators to harmful exhaust gases, decreases environmental pollution, and markedly enhances the safety and environmental sustainability of laboratory teaching. It further promotes the integration of environmental protection concepts into chemical laboratory education.
