为了考察碳酸钾水溶液对催化剂性能的影响,需要不同温度、不同浓度碳酸钾水溶液的粘度系数。由于文献资料上缺乏高浓度、高温度碳酸钾水溶液的粘度系数数据,我们作了测定。一原理液体的粘度系数可用比较法测得,即使待测液体与一已知粘度的同体积液体,分别在相同温度下,以t和t_0时间内流过奥氏粘度计毛细管,则有:
In order to investigate the impact of aqueous potassium carbonate solution on the performance of the catalyst, the viscosity coefficient of potassium carbonate aqueous solution at different temperatures and different concentrations is needed. Due to the lack of literature on the viscosity of high concentration, high temperature potassium carbonate aqueous solution data, we made the determination. The viscosity of a principle of liquid viscosity can be measured by comparison method, even if the measured liquid and a known viscosity of the same volume of liquid, respectively, at the same temperature, t and t_0 flow through the capillary of the Ovens viscometer, are:
