本文用一方程逼近钼硅黄显色的消光-时间曲线,求得了双硅酸的显色速度常数,从而建立了一个在多种聚合度的硅酸水溶液体系中测定单硅酸的方法.利用这个方法,确定单硅酸聚合反应的初速度对其自身浓度是二级反应.根据本实验室提出的硅酸聚合理论,计算了速度常数和相应的活化能,进一步证明了以前所提机制的正确性.

This is to report the results of a kinetic study of the polymerization of monosilicic acid by the use of molybdosilicic acid colorimetiic method.With the establishment of a method of determining monosilicic acid in polymerizing silicic acid system,it is now possible to improve the method of measuring reaction order,spacitic rate constant and energy of activation.
