摘要： 本文对四氢萘和香豆素的反应动力学和反应机理作了研究。实验结果表明, 反应遵从二级反应动力学, 通过协同反应机理进行, 反应中间物是二氢萘。本文提出了二步反应机理, 并对该机理作了进一步讨论和研究。

Abstract: This paper is concerned with the kinetics and mechanism for the reaction between tetralin and coumarin. Second order reaction kinetics has been established and the kinetic parameters have been determined at the same time by the kinetic experiments. It was found that the reaction followed a concerted reaction mechanism instead of a radical one.
A mechanism containing two steps with Dialin as a intermediate has been suggested and the disscusion for it has also been given in this paper.
