The extraction of copper(II) with <I>o</I>-, <I>m</I>-, and <I>p</I>-methylbenzoic acids in 1-octanol was carried out at 25 °C and aqueous ionic strength of 0.1 mol dm<SUP>−3</SUP> (NaClO<SUB>4</SUB>). In contrast to the extraction with benzoic acid, in which only the monomeric copper(II) benzoate is extracted, the dimeric copper(II) species is also responsible for the extraction of copper(II) with <I>o</I>- and <I>m</I>-methylbenzoic acids in 1-octanol together with the monomeric one. On the other hand, <I>p</I>-methylbenzoic acid has a poorer extracting capability than <I>o</I>- and <I>m</I>-methylbenzoic acids and only the monomeric copper(II) species is responsible for the extraction.
