High-purity organic compounds and heavy industrial solvents sourced with complete batch-to-batch traceability.
Within the global petrochemical hierarchy, C9 solvent refers to a complex hydrocarbon mixture predominantly comprised of aromatic hydrocarbons containing nine carbon atoms. Commonly identified under the CAS Registry Number 64742-95-6 (classified as Solvent naphtha (petroleum), light aromatic), this industrial compound serves as a cornerstone formulation component across the coating, agricultural, and polymer industries.
The chemical structural classification of C9 aromatics includes key isomers such as trimethylbenzenes (specifically 1,2,4-trimethylbenzene and 1,3,5-trimethylbenzene), ethyltoluenes, and propylbenzenes. Due to their high boiling point distribution and exceptional solvency power (Kauri-Butanol value typically > 90), these solvents offer unique benefits over aliphatic variations.
For procurement directors and formulation chemists, navigating the synonymous naming conventions is critical to regulatory compliance. C9 Solvent is globally marketed under various trade and technical designations, including:
Shandong Saier Chemical Technology Development Co., Ltd. customizes the refining cut-points to align precisely with standard ASTM D1133 methods, guaranteeing high purity, narrow distillation ranges, and consistent evaporation profiles.
| Product Grade | CAS Number | Boiling Range (°C) | Flash Point (PMCC, °C) | Kauri-Butanol (KB) Value | Aromatic Content (vol%) |
|---|---|---|---|---|---|
| Aromatic Solvent S-100 | 64742-95-6 | 150 – 180 | ≥ 40 | ≥ 90 | ≥ 99.0 |
| Aromatic Solvent S-150 | 64742-94-5 | 180 – 210 | ≥ 62 | ≥ 93 | ≥ 99.0 |
| Aromatic Solvent S-150ND (Low Naph) | 64742-94-5 | 182 – 208 | ≥ 63 | ≥ 92 | ≥ 99.0 (Naphthalene < 0.9%) |
| Aromatic Solvent S-200 | 64742-94-5 | 230 – 290 | ≥ 100 | ≥ 95 | ≥ 99.0 |
At our state-of-the-art facility located in the Qilu Chemical Industrial Park, Zibo City, Shandong Province, Shandong Saier Chemical utilizes continuous fractionating rectification units to isolate C9 and C10 aromatics from cracked petroleum fractions.
Our raw material strategy relies on direct pipeline networks and localized supply integrations with China's tier-1 refining complexes: Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical (Rongsheng), and Hengli Petrochemical. This guarantees a continuous, uniform quality feedstock stream free from paraffinic contamination.
From heavy machinery coatings in Europe to highly stable agrochemical formulas in Southeast Asia, C9 Solvents perform reliably across major sectors.
C9 solvents are used in high-bake stoving enamels, protective industrial coatings, and automotive finishes. High solvency limits paint viscosity, facilitating smooth levelling and defect-free film formation.
Used as a carrier solvent in emulsifiable concentrates (EC) and microemulsions. Its low water solubility and high flash point ensure stable chemical suspensions under harsh field conditions.
Widely used in high-speed offset and gravure printing processes. C9 components provide excellent resin solubility, optimizing ink drying times and reducing dynamic smudging.
Shandong Saier Chemical stands out in the global market through its integrated geographical and logistical position in Linzi, Zibo City, Shandong—the historic cradle of China's petrochemical industry. Our facilities enjoy direct proximity to massive state-owned refining hubs, eliminating high feedstock transportation costs and ensuring continuous supply during global energy market shifts.
To support global supply chains, our factory maintains a dedicated vehicle transport fleet and operates a deep-water shipping integration system through Qingdao Port and Tianjin Port. We export to key international markets in Europe, North America, Southeast Asia, and the Middle East in bulk chemical tankers, ISO tanks, and heavy-duty 200L steel drums.
As global environmental regulations tighten, the demand for traditional aromatic solvents faces scrutiny regarding VOC limits and hazardous air pollutants (HAPs). Saier Chemical's engineering department is actively developing high-purity, environmentally friendly solutions to address these shifts.
Our S-150ND and S-200ND series reduce naphthalene content below 0.9%, meeting European and US EPA classification requirements for low environmental toxicity.
We maintain strict adherence to EU REACH regulations, GHS labeling guidelines, ISO 9001 quality metrics, and ISO 14001 environmental safety protocols.
Our R&D division is piloting bio-aromatic solvents derived from renewable feedstock, aiming to lower carbon footprint indexes by 35% over the next decade.
