High-purity chemical solutions direct from our state-of-the-art refinery and manufacturing plants
Aromatic Solvent C9 (commonly referred to in international trade as Solvent Naphtha Light Aromatic, or C9 Aromatic Hydrocarbon) represents a critical category of high-boiling aromatic organic solvents. Primarily composed of C9 aromatic isomers such as trimethylbenzenes, methylethylbenzenes, propylbenzenes, and indane, these compounds are highly valued for their high solvency parameters, controllable evaporation rates, high flash points, and compatibility with polymer matrices.
At Shandong Saier Chemical Technology Development Co., Ltd., founded in December 2004 with a registered capital of 60 million yuan and located in Zibo's prestigious Qilu Chemical Industrial Park, we have leveraged direct raw material pipelines from refining conglomerates including Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical. Operating at a manufacturing capacity of 720,000 tons per year, we process crude C10 and C9 aromatics into high-grade solvents like Aromatic Solvent S100 (CAS No. 64742-95-6) and S150 (CAS No. 64742-94-5).
To assist global procurement officers and formulation scientists, we maintain strict parameters for our standard Solvent C9. Below is the comprehensive technical specification sheet:
| Parameter Detail | Testing Standard | Specification Values (Aromatic Solvent S100) |
|---|---|---|
| Appearance | Visual inspection | Clear, colorless liquid, free of suspended matter |
| Density @ 15°C (g/cm³) | ASTM D4052 | 0.870 – 0.885 |
| Aromatic Content (% v/v) | ASTM D1319 | ≥ 99.0 |
| Initial Boiling Point (°C) | ASTM D86 | ≥ 155 |
| Dry Point (°C) | ASTM D86 | ≤ 185 |
| Flash Point (Abel Close Cup, °C) | ASTM D93 | ≥ 42 |
| Kauri-Butanol (KB) Value | ASTM D1133 | ≥ 90 |
| Sulfur Content (mg/kg) | ASTM D5453 | ≤ 1.0 |
| Water Content (ppm) | ASTM D1364 | ≤ 500 |
Ensuring consistency, safety, and capacity in global chemical manufacturing
We utilize multi-stage continuous vacuum rectification technology, yielding highly precise distillation fractions that optimize both the KB values and flash points to specific clients' requirements.
Each batch undergoes online gas chromatography (GC) testing. Impurities, trace sulfur, and moisture concentrations are limited strictly in accordance with European REACH registration frameworks.
Strategic positioning in Zibo allows direct access to rail networks, major industrial ports (Qingdao, Tianjin), and pipelines, guaranteeing steady freight rates and secure ocean logistics.
How Solvent C9 provides functional improvements across key global sectors
As a carrier solvent for active ingredients in pesticides, Solvent C9 offers exceptional solubility coefficients. This ensures low-temperature stability, preventing pesticide crystallization during storage, and maximizes the coverage density on crops without phytotoxicity. Our ultra-low naphthalene versions prevent regulatory hurdles in sensitive agricultural zones.
Its high boiling range allows paints to dry at a controlled rate, preventing surface orange peel, blistering, or pinholing. It serves as an excellent diluent for baking enamels, alkyd varnishes, automotive finishes, and screen printing inks, providing superior leveling and high gloss finishes.
Under catalyst and thermal pressure, Solvent C9 cuts are converted into C9 hydrocarbon resins. These resins are widely integrated into hot-melt adhesives, pressure-sensitive tapes, rubber compounding systems, and road marking paints to enhance tackiness and water resistance.
Due to its strong hydrophobic properties and high KB index, C9 solvents cut through heavy mineral oils, asphaltic tars, and protective waxes without attacking common metal substrates, making it the premier choice for heavy machinery maintenance formulations.

The global demand for high-performance organic solvents is transitioning. Driven by stringent environmental guidelines like European VOC limits and EPA guidelines in the USA, modern industrial sectors are moving away from traditional light solvents toward heavier, higher-boiling cuts that exhibit lower vapor pressure. This is where Solvent C9 and C10 options come into play.
By using customized distillation cuts, we help global clients formulate coatings that comply with workplace exposure limits (WEL) and safety profiles without sacrificing dilution ratios or polymer solubility. Innovations at Shandong Saier include our *de-aromatized* or *low-naphthalene* fractions, which drop standard naphthalene components to below 0.1% or even 10ppm limits, mitigating hazardous risk designations while maintaining the superb dissolving power associated with aromatic solvents.
Procuring industrial chemicals on a global scale demands extensive due diligence, particularly regarding safety compliance, GHS regulations, and customs. To ensure seamless transaction execution, we provide:
Clear, direct answers regarding specifications, ordering, and logistics of Solvent C9
Essentially, they represent the same chemical product category. "Solvent C9" defines the molecular structure fraction (C9 aromatic hydrocarbons), while "S100" (or Solvent S100) is the commercial grade name reflecting its initial boiling point of approximately 160°C and flash point above 40°C. Both refer to CAS No. 64742-95-6.
Through our specialized continuous fraction distillation column setups, we separate naphthalene cuts dynamically from the C9 fractions. This allows us to offer low-naphthalene options (Naphthalene < 0.9% or < 0.1%) targeted specifically for global crop protection formulations.
Solvent C9 has a stable shelf life exceeding 24 months when stored in closed containers under cool, dry, and well-ventilated environments, away from direct sunlight, open flames, and oxidizing agents.
Yes, leveraging our dedicated refining facilities and process control systems, we can tailor distillation parameters (IBP and DP ranges) to meet the exact viscosity or evaporation curves required by industrial paint or resin manufacturers.
We support diverse configurations, including standard 200L steel drums (170kg net weight), 20KL/24KL flexitanks, and heavy-duty ISO tank containers, delivering directly from Qingdao Port.
