Polynuclear Aromatic Hydrocarbons (PAHs), characterized by multiple fused benzene rings, represent a vital class of organic chemicals essential for modern synthetic pathways.
Structurally, PAHs display extraordinary stability due to the delocalization of π-electrons across their planar configuration. This inherent thermodynamic stability translates to exceptional performance characteristics in industrial applications, particularly as high-temperature heat transfer fluids, functional organic synthesis intermediates, and specialized non-polar solvents.
As a leading manufacturer, we specialize in separating, refining, and synthetically optimizing these compounds. In industrial applications, our products serve as primary precursors for agricultural chemicals, resins, polymer plasticizers, and high-performance engineering coatings. Our chemical engineering teams leverage advanced fractional crystallization and continuous catalytic hydrogenation techniques to customize distillate ranges, ensuring compliance with strict regulatory limits on volatile compounds while maximizing solvent efficacy.
| Aromatic Solvent Grade | Primary CAS Numbers | Distillation Range (°C) | Kauri-Butanol Value (KB) | Flash Point (PMCC) (°C) | Major Industrial Application |
|---|---|---|---|---|---|
| Solvent S100 | 64742-95-6 | 160 – 180 | > 90 | ≥ 40 | Pesticide EC, High-Gloss Paint Coatings, Ink Formulations |
| Solvent S150 | 64742-94-5 | 182 – 207 | > 92 | ≥ 62 | Emulsifiable Agricultural Concentrates, Industrial Baking Finishes |
| Solvent S180 | 64742-94-5 / Custom | 220 – 290 | > 95 | ≥ 100 | High-Boiling Paint Systems, Metal Working Solvents, Mining Extraction |
| Durene (1,2,4,5-Tetramethylbenzene) | 95-93-2 | 79 – 81 (Melting Point) | N/A (Crystalline) | ≥ 54 | Intermediate for Pyromellitic Dianhydride (PMDA), Polyimide Resins |
Situated in Linzi, Zibo City, Shandong Province—the heartland of China's petrochemical manufacturing—our facility maintains direct pipeline integration with mega-refineries, securing robust raw material supplies and minimizing volatile feedstock transport costs.
Scale guarantees market resilience. Our state-of-the-art distillation towers process up to 720,000 metric tons of refined aromatic solvents and chemical intermediates annually, maintaining inventory buffers for global wholesale partners even during energy supply contractions.
Leveraging deep industrial partnerships with state-backed giants like Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical, we ensure that every batch of crude aromatic feedstock undergoes rigorous gas chromatography-mass spectrometry (GC-MS) pre-screening.
Established in December 2004 with a registered capital of 60 million yuan, Shandong Saier Chemical has evolved from a local solvent blender into a national high-tech enterprise at the forefront of the Chinese chemical industry. Located at No.207, WeiLiu Road, Qilu Chemical Industrial Park, Zibo City, we have pioneered the development of environmentally friendly high-boiling aromatic solvents and synthetic intermediates.
Our primary focus centers on key aromatic hydrocarbons such as S-100, S-150, S-150ND (Naphthalene Depleted), S-180, and S-200, alongside highly specialized products including Durene, Heat Transfer Oil L-QC320, PVC plasticizers, thiophene, 1,3-Cyclohexanedione, MIPK, TMOF, TMOA, HPA, and TMG. This diverse product portfolio satisfies the rigorous requirements of our major domestic clients, including Sinopec and PetroChina, while also serving key markets across Asia, Europe, the Americas, and Southeast Asia.
High-solvency aromatic carriers are essential for producing stable, high-loading emulsifiable concentrates (EC). Our low-naphthalene variants prevent crystallization in cold storage, maintaining agricultural efficacy and crop safety.
We supply ultra-pure Durene (1,2,4,5-tetramethylbenzene) and Pyromellitic Acid (PMA), which serve as key chemical building blocks for polyimide films, electronic coatings, and heat-resistant aerospace resins.
Our formulation L-QC320 represents a significant advance in synthetic thermal oils. Engineered for continuous liquid-phase heat transfer, it exhibits high thermal stability and oxidation resistance at temperatures up to 320°C.
The global chemical industry faces a pressing need for low-VOC, high-boiling solvents with minimal hazardous air pollutant (HAP) footprints. At Shandong Saier Chemical, our research and development programs prioritize modern VOC reduction technologies. By integrating custom-engineered zeolite concentration rotor systems, we optimize internal vapor recovery during refinement. This dramatically reduces stack emissions and helps us achieve our target of lowering the carbon footprint of our operations by 30% by 2030.
For international procurement departments, importing bulk solvents and intermediates like Aromatic Solvent S100 and Durene involves navigating a complex web of logistics, chemistry, and regulatory requirements. Our wholesale distribution system addresses these hurdles through:
Whether you require custom distillation parameters, high-volume chemical intermediates, or low-naphthalene eco-friendly formulations, Shandong Saier Chemical provides consistent, verified quality. Contact our sales engineers to request technical datasheets or sample shipments.
