摘　　要：探索了叔胺分解氟化铵制氨气和氟化氢的方法。以叔胺作为萃取剂,在极性溶剂、水的存在下分解氟化铵释放出氨气;然后,加入高沸点的非极性溶剂蒸发出水和极性溶剂;最后,在更高的温度下,实现叔胺氟化盐的分解,释放出氟化氢;最终,达到将氟化铵分解,并分步释放出氨气和氟化氢。This paper studied the decomposition of ammonium fluoride for production of ammonia and hydrogen fluoride.Tertiary amine as extraction agent,in the presence of water,ammonium fluoride released ammonia in a polar solvent;then adding non -polar solvents with high -boiling point,polar solvents and water was distilled;finally,at higher temperature,the decomposition of tertiary amine fluoride was achieved,hy-drogen fluoride was released;eventually,the decomposition of ammonium fluoride was reached,and the am-monia and hydrogen fluoride were stepwise released.
