Abstract

The process of potassium sulfate crystallization from aqueous solutions in the presence of organic modifiers containing phosphonic, phosphate, sulfonic, sulfate and carboxyl functional groups has been studied. It is shown that the introduction of organic substances has an inhibitory effect on the formation of potassium sulfate crystals. Modifiers containing sulfonic, sulfate and phosphonic functional groups have the greatest inhibitory effect. The effectiveness of modifiers containing carboxyl groups is significantly lower. The formation of stable supersaturated solutions of potassium sulfate is achieved by introducing organic modifiers in an amount of 0.25 – 0.50%.
聚合物和无机改性剂对硫酸钾饱和溶液中相形成过程的影响
研究了在含磷、磷酸盐、磺酸、硫酸盐和羧基官能团的有机改性剂存在下,水溶液中硫酸钾结晶的过程。结果表明,有机物质的引入对硫酸钾晶体的形成有抑制作用。含有磺酸、硫酸盐和膦官能团的改性剂具有最大的抑制作用。含有羧基的改性剂的效果明显较低。通过引入0.25 ~ 0.50%的有机改性剂,可以形成稳定的硫酸钾过饱和溶液。
