Recovery of Triethylamine from a waste of solvent mixture from an antibiotics production

The aim of this study is to perform a batch process to recover and recycle of triethylamine (TEA) from mother liquor that coming an antibiotics production plants. such a homogeneous mixture typically contains Isopropyl Alcohol(IPA),Methylene Chloride(MCH), Methyliso- butylketone(MIBK),2-Ethylhexanoicacid(2-ETH) , DimethylAcetamide(DMAC) ,Acetone (ACT) ,water and Triethylamine Hydrochloride(TEA.C). The recovery of this TEA isn't possible by simple distillation because it form's minimum boiling azeotrope with IPA and water. In this article we try to design a new method to recover and reused this TEA.
