| 摘 要： | 以盐酸羟胺和硫酸为原料，研究了采用反应萃取耦合技术合成硫酸羟胺的方法。结果表明，以三正丁胺-异戊醇混合溶液为萃取剂，反应萃取耦合技术合成硫酸羟胺的条件温和。另外，还考察了温度、反应物浓度、油水体积比等因素对硫酸羟胺产率的影响。在盐酸羟胺和硫酸的浓度均为0.6 mol/L，油水体积比为2.5:1，反应萃取时间为20 min的条件下，一级反应萃取过程后硫酸羟胺的产率可达79.3%。

| Abstract: | The synthesis of hydroxylamine sulfate (HAS) from H2SO4 and hydroxylamine hydrochloride using rreaction-extraction coupling technology has been studied. The results showed that HAS could be synthesized at room temperature using the mixed extractant, tributylamine-isopentanol. The effects of varying several parameters were investigated, including extractant, temperature, oil-water ratio and the initial concentration of reactants. The yield of HAS per pass reached 79.3% when the concentrations of hydroxylamine hydrochloride and HCl were both 0.6 mol/L, the oil-water ratio was 2.5:1 and reaction time was 20 min. |
