Abstract
염석결정화 방법으로 염료용액으로 부터 염료를 결정화하였다. 이번 연구에서 반응성 염료(RB-8, RB-49, RR-218)의 모액의 용해도와 결정화 속도를 연구하였다. 그 결과 연속식 결정화기에서 반응성 염료(RB-8, RB-49, RR-218)에 대한 결정화 속도식 RB-8에서 결정성장 속도 G=7.1×10^(-4)△C0.67와 핵생성 속도 B0=3.1×10^(15)△C[1.2×10^(-8)+△C0.7MT2]이고 RB-49는 결정성장 속도 G=5.2×10^(-4)C0.3441와 핵생성 속도 B0=7.2×10^(15)△C[3.3×10^(-8)+(△C)0.7MT2], RR-218의 결정성장 속도 G=4.4×10^(-4)C0.2361와 핵생성 속도 B0=6.3×10^(15)△C[7.9×10^(-8)+(△C)0.7MT2]의 실험식으로 표현할 수 있다. 또한 특성 곡선 법을 적용하여 입도분포를 계산한 결과 실험식과 일치하는 결과를 확인할 수 있었다.
Salting-out technique was adopted to crystallize dye crystals from dye solution. In this research solubility of dye solution and crystallization kinetics of Reactive dye (RB-8, RB-49, RR-218) was investigated. The empirical expressions of salting-out crystallization kinetics for Reactive dye (RB-8, RB-49, RR-218) in continuous MSMPR crystallizer was RB-8 in crystal growth kinetics G=7.1×10^(-4)△C0.67 and nucleation kinetics B0=3.1×10^(15)△C [1.2×10^(-8) +△C0.7MT2], RB-49 in crystal growth kinetics G=5.2×10^(-4)△C0.3441 and nucleation kinetics B0=7.2×10^(15)△C [3.3×10^(-8) +(△C)0.7MT2], RR-218 in crystal growth kinetics G=4.4×10^(-4)△C0.2361 and nucleation kinetics B0=6.3×10^(15)△C [7.9×10^(-8)+(△C)0.7MT2]. Also, comparison of calculated crystal size distribution applying to characteristic curve method with experimental crystal size showed good agreement.
