C9 aromatic solvent represents a complex hydrocarbon fluid fraction consisting primarily of nine-carbon aromatic molecules. Derived from the catalytic reforming of refinery petroleum streams or steam cracking processes, this heavy aromatic naphtha is highly valued across heavy industries for its exceptional solvency, high flash point, and controlled evaporation rates. C9 Solvent is characterized by components such as trimethylbenzenes, methylethylbenzenes, propylbenzenes, and indane isomers.
As a premier OEM manufacturer, Shandong Saier Chemical manages the entire refinement process. Using modern continuous fractionated rectification technology in our Qilu Chemical Industrial Park facility, we isolate the C9 stream to remove high-boiling residues and volatile lower-carbon fractions. This meticulous control yields premium grades (such as S100 and S150 equivalents) that meet stringent global standards, including low naphthalene tolerances and exact flashpoints suitable for paint coatings, agrochemicals, and industrial resins.
Refineries around the world categorize C9 aromatic solvents by evaporation rates, flash points, and distillation ranges. Standard specifications define these materials by their ability to dissolve active chemical ingredients without causing film degradation or premature curing in coatings. By sourcing raw feedstocks from PetroChina, Sinopec, Zhejiang Petrochemical, and Hengli Petrochemical, we ensure that the initial heavy hydrocarbon feed is highly stable, which translates into reliable physical parameters in the final solvent products.
To assist procurement directors and chemical formulation engineers in specifying C9 based aromatic fluids, the table below outlines the analytical values of standard grades, including the typical ranges achieved in our OEM custom batch manufacturing processes.
| Property Parameter | Aromatic Solvent S100 | Aromatic Solvent S150 | Aromatic Solvent S150ND | OEM Standard C9 |
|---|---|---|---|---|
| CAS Number | 64742-95-6 | 64742-94-5 | 64742-94-5 | 64742-95-6 / Mixed |
| Boiling Range (°C) | 160 - 180 | 182 - 208 | 182 - 204 | 150 - 200 (Customizable) |
| Flash Point (Pensky-Martens, °C) | ≥ 40 | ≥ 62 | ≥ 63 | ≥ 42 |
| Aromatic Content (Vol %) | ≥ 99.0 | ≥ 99.0 | ≥ 99.0 | ≥ 98.5 |
| Naphthalene Content (Wt %) | < 0.1 | ≤ 8.0 | < 0.9 (Low Naphthalene) | < 1.0 |
| Density @ 15°C (g/cm³) | 0.870 - 0.890 | 0.890 - 0.910 | 0.890 - 0.908 | 0.875 - 0.900 |
| Kauri-Butanol (KB) Value | 90 - 95 | 93 - 98 | 93 - 97 | 91 - 96 |
These parameters demonstrate the strict controls over distillation cutoffs. For example, our S150ND (Naphthalene Depleted) solvent is highly requested in agricultural formulation sectors, where strict environmental guidelines limit naphthalene concentrations to mitigate phytotoxicity and aquatic pollution risks.
The procurement of C9 solvent on an industrial scale requires careful navigation of international regulatory frameworks and chemical compliance rules. Buyers must align their supply channels with REACH registration in the European Union, TSCA compliance in the United States, and GHS-compliant Safety Data Sheets globally.
We provide stable supply chains via direct rail and sea routes from the Qilu Industrial Park. We utilize robust packaging formats including 200L steel drums, ISO tanks, and ocean bulk vessels.
Our processing aligns with clean production standards. Our low-naphthalene configurations reduce VOC output and comply with the latest RoHS/REACH environmental safety regulations.
Whether you require elevated flash points, customized distillation fractions, or specific blend combinations, our R&D center optimizes parameters for targeted industrial performance.
At Shandong Saier Chemical, our export division coordinates with local agents across Asia, Europe, South America, and the Middle East. With a total annual capacity of 720,000 tons, we act as a primary manufacturing source, protecting our industrial partners from price volatility by utilizing long-term raw material agreements with state-owned petrochemical giants.
Founded in December 2004, Shandong Saier Chemical Technology Development Co., Ltd. is located in the Qilu Chemical Industrial Park (No. 207, WeiLiu Road, Linzi, Zibo City, Shandong Province). Our chemical industrial zone provides us with seamless pipeline infrastructure, high safety standards, and convenient transport links to international shipping hubs like the Qingdao Port.
Originally established with a registered capital of 60 million yuan, Saier Chemical began with a production focus on basic petroleum fractions and high-boiling aromatic solvents. Over the past two decades, we have expanded our capabilities to supply a diverse catalog, including environmental aromatic solvents (S100, S150, S150ND, S180, S200), Heat Transfer Oils (L-QC320), Durene, β-methylnaphthalene, Dimethyl Disulfide (DMDS), and fine chemical intermediates such as MIPK, TMOF, TMOA, and thiophene.
Our recognition as a National High-Tech Enterprise underscores our commitment to innovation. By upgrading our thermal insulation designs, integrating heat recovery exchangers, and transitioning to digital distributed control systems (DCS), we have reduced unit energy consumption by over 15% while improving batch-to-batch consistency.
Due to its complex hydrocarbon structure and high boiling point profile, C9 aromatic solvent acts as a functional ingredient rather than a simple carrier fluid. Below is an overview of its major downstream applications:
The industrial solvent market is shifting toward eco-friendly chemistry. Rising concerns over VOC emissions, carbon taxes, and worker safety are prompting chemical manufacturers to redesign traditional heavy aromatic formulas. Saier Chemical’s engineering team is actively researching next-generation processes to meet these demands:
