摘要:
分别采用液体比重天平和乌氏黏度计测定了在248.15~298.15 K下及质量分数为0.70～0.85时的磷酸密度和黏度.将测定的磷酸密度和黏度分别与温度和质量分数关联得到相应的关联式.在测定范围内，用相应的关联式计算磷酸水溶液的密度，与测定值相比，最大正相对偏差0.21%，最大负相对偏差-0.23%，平均相对离差0.068%；用相应的关联式计算磷酸水溶液的黏度，与测定值相比，最大正相对偏差3.0%，最大负相对偏差-5.0%，平均相对离差绝对值1.83%.
Abstract:
The densities and viscosities of phosphoric acid were measured by using a hydrostatic balance and an Ubbelohdetype capillary viscometer under the temperature rang was from 248.15 K to 298.15 K and the mass fraction range was from 0.70 to 0.85 respectively. The empirical equation for calculating densities of phosphoric acid was obtained by the connections with the temperature and mass fraction, and the average relative deviation is 0.068%. The empirical equations for calculating viscosities of phosphoric acid were obtained by the connections with the temperature and mass fraction, and the average relative deviation was 1.83%.
