A comprehensive examination of C10-C12 heavy aromatic hydrocarbon streams, production pathways, and performance characteristics.
In the global industrial chemical landscape, Aromatic Solvent S-200 (primarily classified under CAS No. 64742-94-5 or Solvent Naphtha, Heavy Aromatic) stands out as a high-boiling point solvent optimized for demanding environments. Characterized by high solvency, low volatility, and high flash points, S-200 is formulated from complex hydrocarbon streams containing predominantly C10 to C12 aromatic components. Its distillation profile typically spans a range of 230°C to 290°C, making it an essential vehicle for active ingredients that require slow evaporation rates and high thermal stability.
Unlike lower-boiling fractions such as S-100 or S-150, Aromatic Solvent S-200 provides enhanced safety metrics during processing, storage, and transport. The elevated flash point—regularly exceeding 100°C—minimizes volatile organic compound (VOC) emissions during industrial baking cycles and agricultural applications. This high-boiling profile makes it the industry standard for coil coatings, agrochemical emulsifiable concentrates (EC), oilfield injection fluid carriers, and heavy-duty degreasing formulations.
Founded in December 2004, Shandong Saier Chemical Technology Development Co., Ltd. has established itself at the forefront of China's high-purity chemical manufacturing sector. Strategically located at No.207, WeiLiu Road, within the prestigious Qilu Chemical Industrial Park, Linzi, Zibo City, Shandong Province, the company operates at the heart of one of the country's most integrated petrochemical hubs. Supported by a robust registered capital of 60 million yuan, our operations leverage cutting-edge separation, fractionation, and refining processes to deliver high-performance solvents.
From our early stages focusing on basic chemical outputs, we have evolved into an advanced, technology-driven enterprise. Our primary feedstock is securely sourced from major Chinese refining and aromatic giants, including Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical. This guarantees a stable, premium raw material supply chain. Today, Saier Chemical boasts an annual production and processing capacity of 720,000 tons, serving critical manufacturing sectors in Beijing, Shanghai, Tianjin, Hebei, Shandong, and Henan, while exporting high-purity aromatics globally to Asia, Europe, the Americas, and Southeast Asia.

The high solvency power of S-200, as demonstrated by its KB Value of 92-98, allows formulators to minimize total solvent volume while maintaining complete dissolution of organic compounds, resins, and active crop protectants. Crucially, our specialized Naphthalene Depleted (ND) variant satisfies modern environmental regulations by utilizing proprietary low-temperature crystallization and precise fractionation to extract naphthalene down to less than 0.1% without sacrificing solvency.
How Aromatic Solvent S-200 drives performance across diverse regional markets and industries.
In agricultural formulations, S-200 serves as a powerful carrier for active ingredients (fungicides, herbicides, insecticides). Its low volatility prevents rapid droplet crystallization on leaves, ensuring maximum crop absorption and pesticide delivery efficiency.
In bake-cured finishes, S-200 enables uniform film formation. Its high-boiling distillation path ensures slow, regulated evaporation under heat, avoiding surface blemishes, bubbles, or pinholes in metal coating applications.
S-200 acts as a highly effective carrier and diluent for corrosion inhibitors, paraffin dissolvers, and asphaltene dispersants in deep wells. Its high flash point ensures superior safety profile under high-pressure downhole temperatures.
Adapting manufacturing processes to align with global environmental mandates and emerging green solvent technologies.
Developing ultra-low naphthalene cuts (target: < 100 ppm) utilizing advanced liquid-liquid extraction technology to meet the most stringent EU biocidal and cosmetic regulations.
Investigating bio-derived heavy aromatics by co-processing plant oil extracts with traditional petrochemical feeds. This approach reduces overall lifecycle carbon footprints by up to 25%.
Implementing high-efficiency heat recovery systems inside Shandong Saier's distillation towers, aiming for complete loop recovery of volatile fractions and minimizing local factory emissions.
How the structural integration of Shandong Saier Chemical provides consistent, uninterrupted supply to global buyers.
The global sourcing of industrial solvents is highly sensitive to geopolitical shifts, refining capacities, and logistical blockades. Our industrial plant is located inside the Qilu Chemical Industrial Park, one of China's most advanced economic development zones. This location links us directly via pipeline and internal road networks to primary petrochemical suppliers like Sinopec and ChemChina. This geographical proximity ensures an uninterrupted flow of heavy reformates and raw aromatic cuts, insulating our production schedules from raw material shocks.
Furthermore, China's comprehensive transportation infrastructure, combined with our close proximity to the Port of Qingdao (one of the largest deep-water ports globally), allows us to coordinate prompt containerized and bulk chemical shipments. Our automated loading stations support direct tank truck logistics, ISO tank loading, and steel drum packing under strict inert gas blankets, maintaining product purity and dry conditions from the reactor to the terminal.
Aligning with international chemical compliance guidelines for seamless customs processing and handling.
Operating a global chemical export enterprise requires strict adherence to international safety regulations. At Shandong Saier Chemical, we ensure all materials leaving our factory gates comply with the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). Every batch is delivered with updated safety documentation, including multi-language Safety Data Sheets (SDS) and clear packaging label layouts detailing chemical properties and handling guidelines.
For European clients, we actively maintain compliance pathways for REACH registration, facilitating smooth import clearance through European ports. Our facilities are certified under ISO 9001:2015 for quality management, ISO 14001:2015 for environmental systems, and ISO 45001:2018 for occupational health and safety. This guarantees that our processes align with international quality and safety benchmarks.
