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

BTEAC(三乙氯化)为相转移催化剂合成了异烟酸乙酯。

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、碳酸氢反应得到碳酸氢钠微析出和氯化,过滤。

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

副产的氯化在联碱车间加工成氯化、工艺合理经济划算。
