Description

General description

Tributylamine (TBA) is a tertiary amine used as strong base anion (SBA) exchange resin. TBA can also be used as a corrosion inhibitor for mild steel in HCl solution. Additionally, it can be used as a base solvent in various organic synthesis.

Application

Tributylamine may be used as:

• An extraction solvent with CHCA (α-cyano-4-hydroxycinnamic acid) for the selective phospholipids (PLs) extraction from EVOO (extra virgin olive oil) and HO (hazelnut oil).
• A hydroxylating agent in the synthesis of spinel nickel ferrites (NiFe₂O₄) nanoparticles (NPs).

Features and Benefits

In various co-precipitation methods, tributylamine is used as a hydroxylating agent instead of NaOH and NH₄OH since it causes a uniform rise in pH which prevents local supersaturation and promotes homogeneous nucleation throughout the solution.
