Amines separation from mono-, di- and trioctylamines mixture

This study details the development of a simple procedure of separating amines with long hydrocarbon chains. We describe the separation of monooctylamine (MOA), dioctylamine (DOA) and trioctylamine (TOA) from a mixture of three amines. paration of these substances is carried out by liquid–liquid extraction of MOA and TOA from an aqueous mineral acid solution and a nonpolar organic solvent. The results obtained show that the procedure described permits the separation of the three amines and their recovery with minimal losses.
