摘　　要：设计了融入绿色环保理念的综合化学实验——固体酒精的制备及燃烧热的测定。该实验首先将溶液表面张力的测定实验产生的乙醇废液制备成一系列不同乙醇含量的固体酒精,然后进行燃烧热的测定。实验通过用固体酒精代替萘来测定燃烧热,实现了废物的再利用,强化了师生的绿色低碳理念和环境保护意识,调动了学生参与实验的积极性,提高了学生的综合实验能力。A comprehensive chemistry experiment with the integration of the green environmental protection idea,i.e.,the preparation of solid alcohol and the determination of combustion heat is designed.In this experiment,the ethanol waste liquid produced by the determination of the surface tension of the solution is first prepared into a series of solid alcohol with different ethanol content,and then the combustion heat is measured.By using solid alcohol instead of naphthalene to determine the combustion heat,the reuse of waste is realized,the idea of the green low carbon and environmental protection awareness of teachers and students are strengthened,the students＇ enthusiasm to participate in the experiment is aroused,and their comprehensive experimental ability is improved.
