Direct factory export catalog for advanced industrial formulations, synthetic intermediates, and high-purity solvents.
Under the chemical classification of industrial hydrocarbons, C9 Solvent (often termed C9 aromatic hydrocarbon or heavy aromatic naphtha) refers to a liquid mixture containing nine carbon atoms per molecule. The composition is primarily dominated by alkylated benzenes, which include isomer combinations of trimethylbenzenes (such as pseudocumene, mesitylene, and hemimellitene), methylethylbenzenes, indane, and propylbenzenes.
These hydrocarbons are synthesized through refined downstream petrochemical processing of crude refinery streams—specifically the C9 aromatic fractions generated during reformate extraction or pyrolysis gasoline (pygas) co-production. Renowned for their high solvency parameters, elevated boiling ranges, and slow evaporation rates, C9 solvents serve as critical carrier fluids and synthesis building blocks in industrial formulations worldwide.
Understanding the molecular properties of C9 fractions allows formulators to customize evaporation dynamics and compatibility profiles:
| Chemical Parameter | Aromatic Solvent S100 | Aromatic Solvent S150 |
|---|---|---|
| CAS Number | 64742-95-6 | 64742-94-5 |
| Boiling Range (°C) | 160 – 180 °C | 180 – 210 °C |
| Flash Point (°C, PMCC) | ≥ 40 °C | ≥ 62 °C |
| Aromatic Content (vol%) | ≥ 99.0% | ≥ 99.0% |
| Kauri-Butanol (KB) Value | 90 - 95 | 92 - 97 |
Founded in December 2004 — Pioneering Quality and Sustainability in Aromatic Hydrocarbons.
Established at No. 207, WeiLiu Road, within the national-level Qilu Chemical Industrial Park, Linzi, Zibo City, Shandong Province, Shandong Saier Chemical Technology Development Co., Ltd. has developed into an industry-leading manufacturer with a robust production capacity of 720,000 tons per year. Built upon a strong registered capital of 60 million yuan, our enterprise has established highly secure raw material channels from premier global energy companies including Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical.
Our initial capabilities centered around high-boiling aromatic solvents including S-100, S-150, S-150ND, S-180, and S-200, along with auxiliary lines of Heat Transfer Oils L-QC320, Durene, PVC plasticizers, and high-purity fine chemical intermediates (Thiophene, 1,3-Cyclohexanedione, MIPK, TMOF, TMOA, HPA, TMG). Today, our sales reach key Chinese industrial hubs (Beijing, Shanghai, Tianjin, Hebei, Shandong, Henan) as well as international markets across Asia, Europe, the Americas, and Southeast Asia.
Strategic Industrial Location: Being nested in the Qilu Chemical Industrial Park enables direct pipeline linkages, minimizing logistic delays and optimizing manufacturing costs.
Premium Feedstocks: Consistent reliance on primary extraction products from Sinopec and PetroChina refineries ensures that our C9 aromatic solvents are free from paraffinic impurities, ensuring consistent solvency.
Diversified Product Portfolio: Providing both bulk aromatic solvents and high-purity chemical intermediates under one integrated supply platform.
Driving innovation in separation efficiency, environmental compliance, and high-performance solvent modification.
By employing advanced, multi-column continuous vacuum rectification, Saier Chemical achieves precise boiling point cuts. This selective separation controls isomer ratios to tailor evaporation rates, catering specifically to advanced coil and automotive OEM coatings.
Addressing international environmental and toxicology demands, our R&D pipeline prioritizes ND (Naphthalene-Depleted) grades. By reducing naphthalene concentrations to under 1% and 0.1% respectively, we produce S150ND and S200ND variants that support safer formulations.
In accordance with China's Peak Carbon and Carbon Neutrality directives, our factory integrates waste-heat recovery systems and vapor combustors (RTO) into the fractionation processes, yielding a significant decrease in energy consumption per metric ton.
Delivering specialized solvent characteristics designed for diverse industrial applications.
For emulsifiable concentrates (EC) in crop protection, solvents must possess strong solubility to keep active ingredients dissolved under low temperature storage conditions. The high Kauri-Butanol value of our C9 and C10 aromatic solvents (S150 and S200) prevents crystallization of active compounds, maintaining stable performance in agricultural sprays.
In high-bake coatings, coil coatings, and automotive finishes, the evaporation rate of the solvent system determines the smoothness and adhesion of the final dry film. Our C9 aromatic fractions evaporate gradually, allowing the resin polymer chains to flow and level properly, preventing surface defects such as orange peel or pinholes.
Operating a chemical manufacturing facility at scale requires robust logistical integration and quality monitoring. Located within the highly integrated Qilu Chemical Industrial Park, Saier Chemical utilizes advanced automation and computerized control systems to maintain a production capacity of 720,000 tons per year.
Our raw materials are delivered directly via pipeline and dedicated chemical transport fleets from major refineries. This proximity minimizes raw material price volatility and shipping delays. Furthermore, our strategic proximity to Qingdao Port allows for efficient bulk loading and container dispatch, ensuring rapid distribution to major international shipping routes.

Frequently asked questions concerning the chemical characteristics, industrial applications, and logistics of C9 aromatic solvents.
C9 aromatic solvents are composed almost entirely of ring-structured alkylbenzenes, providing high solvency parameters (KB value over 90). In contrast, paraffinic mineral spirits consist of straight or branched-chain alkanes, which have lower solvency. Aromatic solvents are preferred for dissolving tough resins such as alkyds, epoxies, and polyurethanes, and are often used in high-performance coatings and pesticide formulations.
Naphthalene is classified as a hazardous chemical and a potential carcinogen. To meet strict international environmental, health, and occupational safety regulations (such as EU REACH), chemical manufacturers require low-naphthalene versions. In response, Saier Chemical produces Naphthalene-Depleted (ND) grades, reducing naphthalene levels to under 1% and 0.1% respectively, helping formulators avoid precautionary hazard labels.
We offer multiple packaging configurations including standard 200L steel drums (180kg net weight), 1000L IBC containers, and ISO tank shipments for large bulk consignments. Backed by our 720,000-ton annual capacity, standard order processing and delivery to local container terminals typically takes 10 to 15 days, ensuring stable logistics timelines.
Our raw materials are sourced directly from reputable refineries like Sinopec and PetroChina.
