Applications of Di-N-Octylamine in Industrial Manufacturing

Di-N-Octylamine performs critical roles in several downstream industrial segments that prioritize consistent formulation performance and strict compliance with sector-specific regulations. As a direct manufacturer, we ensure deep integration with partners’ production processes, supporting a sustainable supply chain for precise applications.

1. Rubber Accelerators Production

Rubber chemicals manufacturers employ Di-N-Octylamine as an essential intermediate during the synthesis of sulfenamide and thiuram accelerators, serving both the tire and mechanical rubber goods markets. This amine’s alkyl structure facilitates the building of accelerator molecules with properties tailored for high-speed vulcanization and finished rubber resilience, especially where resistance to environmental stress is prioritized. Its role is not replaceable by aliphatic amines with shorter carbon chains, as the octyl groups impart low volatility and compatibility with various rubber systems.

Industry compliance standards

• ISO 9001:2015 for quality management in chemicals manufacturing
• ASTM D4670 / D4670M standards for rubber compounding ingredients
• REACH Regulation (EC) No 1907/2006 for chemical safety in the EU
• Environmental Protection Law of China (applicable for domestic facilities)

Typical usage ratio

• As a chemical intermediate: 0.3–2.1 molar equivalents, depending on the specific accelerator target compound; adjustment based on rubber grade and accelerator performance requirements

Downstream process integration

• Directly added to batch reactors during synthesis of sulfenamide or thiuram accelerator intermediates; typically introduced after initial charge of raw materials and before oxidative or condensation stages

Final product types

• Delayed-action rubber accelerators (e.g., NOBS, TMTD, TBBS grade chemicals)
• Radial and bias tire compounds
• Industrial conveyor belt vulcanization agents
• Rubber hose and gasket formulations

2. Agrochemical Active Ingredient Synthesis

Agrochemical producers adopt Di-N-Octylamine as a core building block for manufacturing select herbicide and pesticide actives, including certain urea and carbamate derivatives. In these formulations, alkyl chain length has a marked impact on active performance, controlling volatility and crop surface retention. Our product’s consistency allows downstream processors to meet stringent tolerances outlined by regional regulators, minimizing impurities that could affect field efficacy or crop residuals.

Industry compliance standards

• FAO/WHO Specifications for Plant Protection Products
• EU Regulation (EC) No 1107/2009 for plant protection product approval
• US EPA Guidelines for Pesticide Registration (OPPTS 830 Series)
• GB 2763-2021 Maximum Residue Limits for Pesticides in Food (China)

Typical usage ratio

• Intermediate for actives: 0.5–1.5 molar ratio in condensation or alkylation steps; precise dosage determined by targeted yield and purification needs

Downstream process integration

• Charged during key condensation steps to prepare N-octyl carbamate or urea derivatives; usually added post-solvent loading and prior to activating or alkylating agents

Final product types

• Pre-emergent herbicide technical concentrates
• Insecticide formulation intermediates
• Finished ready-to-spray crop protection solutions
• Controlled-release granules and formulations for field application

3. Antistatic Agent Manufacturing for Plastics

Manufacturers in the plastics additives sector utilize Di-N-Octylamine to prepare specialized antistatic agents used in the production of polyolefin films, rigid packaging materials, and electrical component housings. The compound’s hydrophobicity and compatibility allow for the formation of long-lasting, migration-resistant antistatic properties, specifically sought after in packaging that demands low surface resistivity and high processability.

Industry compliance standards

• US FDA 21 CFR 178.3130 (Antistatic and Antifogging Agents in Polymers)
• EU Regulation (EU) No 10/2011 on materials and articles intended to come into contact with food
• EN IEC 61340-5-1 for electrostatics in electronic component environments
• Chinese GB 9685 standard for food contact additives

Typical usage ratio

• For base antistatic compound synthesis: typically 2–7% by weight relative to total additive formulation; final additive blends used at 0.1–0.5% in polymer processing depending on resistivity targets and film thickness

Downstream process integration

• Condensed with fatty acids or sulfonates to produce amide or quaternary ammonium antistatic agents before let-down into masterbatch systems or direct dry blending during resin compounding

Final product types

• Polyethylene and polypropylene films for food and electronics packaging
• Injection molded antistatic housings for consumer electronics
• High-frequency cable insulation
• Cleanroom-grade plastic partitions and trays

4. Corrosion Inhibitor Production for Industrial Lubricants

Lubricant formulators integrate Di-N-Octylamine in the manufacture of oil-soluble corrosion inhibitors, principally for industrial gear oils, turbine oils, and compressor lubricants. The bulky octyl chains render this amine especially effective when synthesizing amide and amine carboxylate inhibitors that coat metal surfaces under severe operating conditions, extending machinery service life in high-humidity or saline environments. This application focuses on metals prone to acid-catalyzed corrosion, such as iron and steel substrates.

Industry compliance standards

• ASTM D665 for evaluating rust-preventive characteristics of lubricating oils
• ISO 12925-1 for industrial gear oils
• DIN 51517 for lubricating oils in industrial applications (Germany)
• REACH registration and SDS compliance for finished inhibitors

Typical usage ratio

• 2–5% by weight relative to inhibitor concentrate; final inhibitor blends added at 0.02–0.20% in base oils, tailored by expected water ingress and system metallurgy

Downstream process integration

• Introduced in the synthesis of amide inhibitors via direct amide formation with carboxylic acids; inhibitor concentrate then emulsified or blended into base lubricating oils during kettle blending

Final product types

• Premium industrial gear and turbine oils
• Hydraulic system lubricants for critical infrastructure
• Corrosion-protective fluids for metalworking
• Long-life compressor oils for marine or coastal installations
