化学动力学在地球化学(特别是成矿作用地球化学)研究中有极其重要的作用,其主要应用包括七个方面。本文重点介绍了地球化学中化学动力学的实验研究方法以及碳酸盐、硅酸盐、氧化物和硫化物等矿物的反应动力学实验成果;介绍了Helgeson的质量迁移理论及其研究热液在围岩中的运移方面的应用,并在热力学性质和动力学行为两方面研究了围岩的离解作用、蚀变作用与矿化作用及其相互关系。

A water—jacketed polarimeter tube has been designed for the experiment of inversion of cane sugar.This design does not change any parts of pol- arimeter,the rate constant and the activation energy of reaction for inve- rsion of cane sugar were determined by the water-jacketed polarimeter tube. The result obtained was in good agreement with the literature value.

本文用自行设计的恒温样品管,在不改变旋光仪任何部件的情况下,测定了不同温度下蔗糖转化反应的速度常数及反应的活化能,所得结果与文献值一致。化学动力学实验对化学动力学理论的形成和发展起着十分重要的作用。而做好动力学实验及准确地测定动力学数据的重要条件是恒温。对于蔗糖转化反应动力学数据的测定,目前大多采用 WZZ—1或 WZZ—T 型旋光仪,该仪器没有恒温装置,因此在实验过程中,温度的变化无法控制,处理实验数据所得的线性关系较差。这样对于学生做好实验,养成严格的科学态度,以及对于动力学研究,都是不足的。针对这一问题,我们设计制作了恒温样品管装置,摸索了实验条件,测定了不同温度下蔗糖水解反应的速度常数及反应的活化能,并验证了实验装置的可靠性。
