Overview
1-Octylamine is an aliphatic primary amine with an eight-carbon chain. It is widely utilized in industrial chemistry due to its reactive amino group and hydrophobic tail. As a versatile intermediate, it participates in reactions like alkylation and amidation. Commonly produced via the reaction of octanol with ammonia or through nitrile reduction, it is a key raw material for surfactants and specialty chemicals. Its dual functionality (polar head and non-polar tail) makes it valuable in formulations requiring emulsification or surface modification.
Physical and Chemical Properties
1-Octylamine is a low-viscosity liquid with a strong amine odor, characteristic of primary amines. Its flammability (flash point ~60°C) and corrosivity necessitate careful handling. The compound exhibits typical amine reactivity, forming salts with acids and participating in nucleophilic substitutions. Its limited water solubility but high miscibility with organic solvents like ethanol makes it suitable for non-aqueous systems. The boiling point (175-178°C) allows for distillation purification, while the low melting point (-1°C) ensures liquid state at room temperature in most climates.
Main Applications
In corrosion inhibition, 1-octylamine forms protective films on metal surfaces, particularly in oilfield applications. As a surfactant, it serves as a precursor for quaternary ammonium compounds used in disinfectants and fabric softeners. The rubber industry employs it as an accelerator in vulcanization. It also acts as a pH adjuster in agrochemicals and a building block for pharmaceuticals. Emerging uses include nanotechnology, where it functionalizes nanoparticles for dispersion stability.
Safety and Storage
Classified as flammable and corrosive, 1-octylamine requires storage in tightly sealed containers (stainless steel or HDPE) under nitrogen blanket to prevent oxidation. Grounding is essential to avoid static discharge during transfer. Exposure controls include fume hoods and chemical-resistant gloves (nitrile or neoprene). Spills should be neutralized with dilute acetic acid before absorption with inert material. Firefighting requires alcohol-resistant foam—water jets may spread flames.
B2B Procurement Guide
Industrial buyers should specify purity (typically 98-99%), moisture content (<0.5%), and absence of heavy metals. Bulk shipments (200kg drums or 1000kg IBCs) offer cost advantages but require proper handling equipment. Reputable suppliers provide COA (Certificate of Analysis), SDS, and ISO certifications. Just-in-time procurement is advised due to limited shelf life (12-18 months). Regional pricing varies with raw material (octanol) fluctuations and logistics costs.
