EXTRACTION OF MALIC ACID WITH ALIQUAT-336 IN EXISTENCE OF DILUENT SOLVENTS

In this study, the effect of diluents in different structures on the extraction of malic acid from aqueous solutions with Aliquat-336, named chemically as tricapril metyl ammonium chloride, was investigated. Diluting solvents used in experiments are heptane, toluene, kerosene, cyclohexane and methyl isobuthyl ketone (MIBK). Furthermore, the effect of MIBK+Heptan mixture in 1:1 volume ratio on the extraction was investigated also. The extraction was performed at room temperature by means of a shaker. The distribution coefficients and loading factors were calculated from the experimentally determined results, presented as tables and graphics, and compared with each other. Among the diluents used in this study, the best results were obtained with MIBK.

MALÝK ASÝDÝN ALÝQUAT-336 ÝLE SEYRELTÝCÝ ÇÖZÜCÜLER VARLIÐINDA EKSTRAKSÝYONU

Bu çalýþmada, Malik asidin sulu çözeltilerden, kimyasal ismi trikapril metil amonyum klorür olan Aliquat-336 ile ekstraksiyonuna farklý kimyasal yapýdaki seyrelticilerin etkisi incelenmiþtir. Çalýþmada kullanýlan seyrelticiler Heptan, Toluen, Kerosen, Siklohekzan ve Metilizobutilketon (MIBK)’dur. Bu çözücülerin yaný sýra MIBK+Heptan’ýn hacmen 1:1 oranýndaki karýþýmý da kullanýlarak ekstraksiyon üzerine etkisi incelenmiþtir. Ekstraksiyon iþlemleri oda sýcaklýðýnda ve bir çalkalayýcý yardýmýyla gerçekleþtirilmiþtir. Elde edilen deneysel sonuçlardan yararlanýlarak daðýlma katsayýlarý ve yükleme deðerleri hesaplanmýþ, sonuçlar tablolar ve grafikler halinde sunularak karþýlaþtýrýlmýþtýr. Kullanýlan seyrelticiler içerisinde en iyi sonucu MIBK'un verdiði görülmüþtür.
