염화암모늄에 의한 황화철의 염소화 반응(I)
Chlorination of Iron Sulfide with Ammonium Chloride(I)
황화철의 활용방안 및 염화암모늄을 새로운 염소원으로서의 사용가능성을 조사하기 위하여 N2 기류하에서 염화암모늄에 의한 황화철의 염소화반응을 시도하였다.
황화철은 염화암모늄에 의해 FeCl2로 염소화되었으며 반응온도 375 ℃, 반응시간 1 hr, 염화암모늄의 양은 mole ratio 9.0, N2 가스의 유량 100 ㎤/min의 조건하에서 그 전환율은 97.2 %로서 염화암모늄은 효과적인 염소화제였다.

The chlorination of iron sulfide with NH4Cl was thermodynamically and experimentally investigated in order to find the possibility of NH4Cl being an alternative chlorine source and the new process for the beneficiation of iron sulfide.
Iron sulfide was converted to FeCl2 in this chlorination and NH4Cl was a good chlorine source.
The optimum conditions for this chlorination were that reaction temperature 375 ℃, reaction time 1 hr, NH4Cl mole ratio to iron sulfide 9.0 and N2 flow rate 100 ㎤/min（reactor size : ID=3.0 ㎝）
Under above mentioned conditions, the conversion of iron sulfide to FeCl2 was 97.2 %.
