有机胺法分解氯化铵的工艺
Decomposition of ammonium chloride by organic amine
摘要
Abstract
The decomposition of ammonium chloride(NH4Cl) in the presence of organic amine under anhydrous conditions was studied,and the effect of reaction conditions on release of ammonia (NH3) and hydrogen chloride (HCl) was investigated. Moreover,the best organic amine for separating ammonia (NH3) and hydrogen chloride (HCl) from decomposition of ammonium chloride(NH4Cl) was determined from trihexylamie,tris (2-ethylhexyl) amine,trioctylamine and trilaurylamine. The results show that trihexylamine (THA) has advantages of shorter reaction time and higher yield of ammonia (NH3) and hydrogen chloride (HCl) compared with the other organic amines. The yield of ammonia (NH3) can reach 97.5% under the reaction conditions ofn(THA)∶n(NH4CI) =1.4∶1,n(Isoamylol)∶n(NH4Cl) = 6.84∶1,N2 flow rate 140mL/min,temperature 132℃ and reaction time 3.5h. On the hand,the yield of hydrogen chloride (HCl) can reach 94.65% under the reaction conditions of tetradecane∶trihexylamine hydrochloride=11∶1,N2 flow rate 260mL/min,temperature 223℃ and the reaction time 4.5h.关键词
