Aniline oil (Pure Aniline, C6H7N) is one of the most critical primary aromatic amines used in the global chemical synthesis industry. Known for its distinct aromatic odor and chemical reactivity, it serves as a foundational building block for downstream products ranging from polyurethanes to synthetic dyes.
However, sourcing the right grade of aniline oil requires deep technical understanding. In this guide, we break down what aniline oil really is, its core industrial applications, and 9 essential tips to help you choose the best supplier for your manufacturing needs.
Aniline oil is an organic compound derived from the catalytic hydrogenation of nitrobenzene. Unlike natural oils, it is a pure chemical intermediate. In its pure form, it is a colorless, oily liquid that darkens upon exposure to air and light due to oxidation.
As a highly reactive aromatic hydrocarbon, aniline serves as an excellent solvent, antioxidant, and chemical reactant in complex syntheses.
Aniline oil is prized across multiple heavy industries for its versatility:
Polyurethanes (MDI): Over 70-80% of global aniline is consumed to produce Methylene diphenyl diisocyanate (MDI), used in rigid/flexible PU foams and automotive parts.
Rubber Processing: It is a key precursor for rubber vulcanization accelerators and antioxidants (6PPD), enhancing tire durability.
Dyes and Pigments: It is the backbone of the synthetic dye industry (indigo, azo dyes) for textiles, leather, and inks.
Agrochemicals & Pharmaceuticals: Used as an intermediate for manufacturing herbicides, fungicides, and APIs (like paracetamol).
Ensure the supplier provides a minimum purity of ≥ 99.9% for standard industrial synthesis. High-purity aniline prevents unwanted side reactions in your production line.
Excessive moisture (H2O) and residual nitrobenzene can affect catalytic efficiency. Demand a Certificate of Analysis (COA) specifying moisture levels (typically ≤ 0.1%).
Aniline oxidizes easily when exposed to air. Look for suppliers offering tightly sealed Iron Drums (200kg/210kg) or ISO Tanks with nitrogen blanketing (nitrogen flushing) to preserve quality during maritime transit.
Aniline oil is a Class 6.1 Toxic Substance (UN 1547). Your supplier must possess valid export licenses, compliant SDS (Safety Data Sheets), and strong relationships with top shipping lines experienced in DG cargo.
Aniline prices fluctuate with crude oil and benzene markets. Partner with a supplier that maintains massive inventory buffers to guarantee continuous supply during market volatility.
Ensure the product complies with international regulatory frameworks such as REACH (for the European market) and relevant ISO quality management standards.
To mitigate quality risks, choose a supplier that supports third-party pre-shipment inspections like SGS or Bureau Veritas to verify quantity and specifications at the loading port.
A reliable B2B supplier should be willing to provide small testing samples for your R&D lab to check compatibility before committing to an FCL (Full Container Load) order.
Chemical sourcing isn't just about the product; it's about solutions. Choose a partner that offers technical data support, flexible payment terms (L/C, T/T), and 24/7 post-sales tracking.
Aniline oil is an indispensable powerhouse in the modern chemical industry, driving innovation in polyurethanes, rubber, and textiles. When selecting aniline oil, the focus should always be on purity, storage stability, logistics safety, and supplier reliability.
