亚硝酸铵溶液生产工艺研究

Study on production process of ammonium nitrate solution

亚硝酸铵属于基础化工原料,在许多领域应用广泛。生产己内酰胺的原料主要是硫酸羟胺,硫酸羟胺可运用亚硝酸铵溶液制取。生产亚硝酸铵溶液的方法有很多种。本文结合实验室结果,以氮氧化合物为原料,对用碳酸氢铵溶液吸收法来制备亚硝酸铵溶液的生产工艺进行探讨。

Ammonium nitrite is a basic chemical raw material, which is widely used in many felds. The main raw material for producing caprolactam is hydroxylamine sulfate, which can be made from ammonium nitrosammonate solution. There are many ways to produce ammonium nitrate solution. Based on the laboratory results, the production process of ammonium nitrate solution by ammonium bicarbonate solution absorption method was discussed.
