摘要/Abstract

摘要： 用苦卤与工业液碱NaOH水热反应合成碱式硫酸镁(MOS)晶须，考察了原料配比、反应温度、液碱浓度及反应时间对液相组成和产品形貌的影响，用XRD和SEM等手段对产品进行表征，并对反应后母液进行钾盐和钠盐分离。结果表明，适宜的MOS合成条件为Mg2+与OH?摩尔比1:1.5及NaOH浓度4 mol/L、反应温度200℃、反应时间7 h。合成晶须后的母液按Mg2+与OH?理论摩尔比1:2反应，使母液中Mg2+完全转化为Mg(OH)2晶体。除镁后母液根据0和25℃时Na+, K+//Cl?, SO42??H2O四元体系相图、25和100℃时NaCl?KCl?H2O三元体系相图，通过蒸发浓缩结晶和低温结晶分离出NaCl, Na2SO4?10H2O和KCl。
