Fund Project:

Extraction of catechol and 1,3,5-trihydroxybenzene hy tri-n-octylamine(in ben-zene or octanol)lias been studied.The effects of organic diluents, pH and concentration of Na₂SO₄ on the distribution coefficient D have been investigated.FTIR analysis of the organic phase shows that trioctylamine forms complexes with phenols through hydrogenbond or ionic association.The compositions of complexes have been determined.
- complexation extraction,
- catechol,
- trihydroxybenzene,
