Synthesis of bio-based surfactants from cashew nutshell liquid in water†
Abstract
3-Pentadecylcyclohexylamines were synthesised via Pd/C-catalysed reductive amination of crude cashew nutshell liquid, an underused waste product, with hydrogen in water. The short, modular, and waste-minimised synthetic approach enables access to structurally diverse neutral, cationic, and zwitterionic tenside derivatives.
