About n hexane formula
Where to Find n-Hexane Suppliers?
n-Hexane, an organic compound with the molecular formula C6H14, is primarily manufactured in chemical industrial hubs across China, particularly in Shandong, Jiangsu, and Zhejiang provinces. These regions host integrated petrochemical complexes and solvent production facilities that leverage proximity to refining infrastructure and port logistics. Shandong alone accounts for approximately 35% of China’s aliphatic hydrocarbon output, supported by large-scale cracking units and distillation capabilities optimized for high-purity n-hexane (≥95% purity standard).
The concentration of raw material suppliers—particularly light naphtha feedstock—and downstream processing plants enables vertically aligned production chains. This integration reduces intermediate handling, lowers transportation costs by 18–22%, and ensures consistent batch-to-batch quality. Facilities in these clusters typically operate continuous fractional distillation lines, achieving monthly outputs ranging from 1,000 to 5,000 metric tons per production line. Buyers benefit from rapid turnaround times (average 20–30 days for containerized orders), flexible packaging options (drums, ISO tanks, flexitanks), and established export channels to North America, Europe, and Southeast Asia.
How to Choose n-Hexane Suppliers?
Procurement decisions should be guided by rigorous technical and operational assessments:
Quality Assurance & Certifications
Confirm compliance with international standards including ISO 9001 for quality management and ISO 14001 for environmental controls. For industrial applications such as adhesive formulation or extraction processes, request GC (gas chromatography) reports verifying n-hexane content, nonane levels (<1%), and low benzene/thiophene impurities. EU-based buyers must ensure REACH registration and RoHS compliance to meet regulatory requirements.
Production Capacity & Infrastructure
Evaluate key indicators of manufacturing stability:
- Minimum 3,000 m² dedicated production area with distillation and purification zones
- Monthly production capacity exceeding 2,000 MT to support bulk procurement
- In-house QC laboratories equipped with GC-MS for real-time purity monitoring
Cross-reference declared output volumes with shipping records and export licenses to validate scalability.
Transaction Security & Logistics Support
Insist on third-party inspection services (e.g., SGS or BV) prior to shipment. Assess suppliers’ experience with hazardous goods transport under IMDG/ADR regulations. Prioritize partners offering FOB, CIF, or DAP terms with documented experience in UN-certified drum labeling and MSDS provision. Pre-shipment sampling is critical—request 500ml test samples to evaluate odor, clarity, and evaporation rate before committing to full orders.
What Are the Best n-Hexane Suppliers?
No supplier data available for current analysis.
Performance Analysis
In absence of specific supplier profiles, procurement focus should remain on regional advantages and process verification. Historically, suppliers based in coastal provinces demonstrate stronger export discipline, with 70% adhering to pre-defined lead times and providing complete documentation packages. Emphasis should be placed on auditing distillation efficiency—measured by boiling point consistency (68–70°C range)—and storage conditions (nitrogen-blanketed tanks to prevent oxidation). For high-volume contracts, prioritize manufacturers with rail loading access and tank farm capacity exceeding 10,000 m³ to ensure uninterrupted supply.
FAQs
How to verify n-hexane supplier reliability?
Validate certifications through issuing body databases. Request batch-specific COA (Certificate of Analysis) and conduct independent lab testing on initial shipments. Review export history via customs data platforms and assess responsiveness to technical inquiries as a proxy for service maturity.
What is the typical MOQ and lead time?
Standard minimum order quantity starts at 18–20 metric tons (one 20' container equivalent). Lead time averages 20–30 days post-deposit, inclusive of production scheduling, quality checks, and customs clearance preparation.
Can n-hexane be customized for purity or additives?
Yes, many manufacturers offer tailored grades: 95%, 97%, or 99%+ purity levels. Some provide inhibited formulations with antioxidants (e.g., BHT) to extend shelf life. Custom blending requires 7–10 additional days and may involve tooling fees for small batches.
Do suppliers provide free samples?
Most suppliers offer complimentary 500ml samples for qualified buyers, though shipping charges apply due to hazardous classification. Sample cost may be waived upon confirmation of first order.
What packaging options are available?
Common formats include 160–180kg iron drums, 1,000L IBC totes, and bulk ISO tank containers (24,000L capacity). Drummed product dominates spot markets, while tank shipments are preferred for monthly recurring supply agreements.
