The effect of TOA (tri-n-octylamine), TOMA (tri-n-octylmethylammonium iodide), DEDA (N,N{prime}-didodecylethylenediamine), DEDMA (N,N{prime}-didodecyl-N,N{prime}-tetramethylethylene-diammonium diiodide), and NDM (N-dodecylmorpholine) upon the solvent extraction of boron from CaCl{sub 2} brine with CTMP [2-chloro-4(1,1,3,3,-tetramethylbutyl)-6-methylolphenol] in petroleum benzine has been studied. In order to extract boron effectively and reject other cations such as Ca{sup 2+}, the extraction of boron with CTMP was investigated in terms of extractant, the concentration of an amine, and solvent polarity. The results show that in the presence of long-chain amines, boron extraction, hence distribution, and an increase in selectivity are observed when CTMP is used together with long-chain amines and their ammonium salts in petroleum benzine.
