INTRODUCTION

Oleylamine is a long-chain (C18) primary fatty amine derived from natural fatty acids, typically sourced from vegetable oils. It is produced from oleic acid through conversion of the carboxylic acid group (–COOH) into an amine group (–NH₂). With its optimal balance of hydrophobic chain length and reactive amine functionality it serves as a versatile and dependable building block for high-performance formulations.  It offers excellent surface-active properties, broad compatibility with organic systems, and effective corrosion inhibition performance, making it suitable for a wide range of industrial and specialty applications.

Manufacture

Oleylamine is manufactured from naturally derived C18 unsaturated fatty acids (oleic acid) obtained from vegetable oils. Oleic acid is reacted with ammonia at elevated temperatures to produce oleamide. The resulting oleamide is then selectively hydrogenated using a suitable catalyst—typically Ni, Co, or Cu-based—under high hydrogen pressure to yield oleyl amine.
