ammonium chloride

Synthesis of ethyl iso nicotinate using BTEAC (benzyl triethyl ammonium chloride) as phase transfer catalyst was studied.

以BTEAC(苄基三乙基铵)为相转移催剂合了异烟酸乙酯。

First,brine is reacted with ammonium hydrocarbonate to obtain the sodium hydrocarbonate and the ammonium chloride solution,and then filtrated.

卤水制备纯碱分两步进行,第步用卤水、碳酸氢铵反应得到碳酸氢钠微溶析出和铵溶液,过滤。

The ammonium chloride is obtained by processing the by-product solution of ammonium chloride in the workshop of coordinative producing alcali.

副产的铵溶液在联碱车间加工铵、工艺合理经济划算。
