摘要

以Pitzer电解质溶液理论为基础

引入离子强度函数来表达高温 (1 0 0℃ )时两电解质之间及电解质与非电解质之间的作用系数

计算了 2 5℃和 1 0 0℃时H3BO3-Na2 SO4-NaCl-H2 O四元体系的溶解度

计算值与实验测定值相吻合 .应用该四元体系的相图讨论了用西藏天然硼砂生产硼酸的工艺过程 .

Abstract

On the basis of Pitzer model(1973)

ionic strength is introduced to express the interaction parametersbetween two kinds of electrolyte and those between electrolyte and non-electrolyte at a high temperature of 100 ℃.The solubilities of H_3BO_3-Na_2SO_4-NaCl-H_2O system at 25 ℃ and 100 ℃ are calculated

the calculated values agree with experimental results well. With this quarternary system phase diagram

the technology of producingboric acid from natural borax ore in Xizang China is discussed.
