A technical review of C9-C12 aromatic complexes, distillation dynamics, and modern environmental criteria.
Industrial aromatic solvents are heavy hydrocarbon mixtures distilled from petroleum fractions, composed predominantly of aromatic compounds with molecular counts starting at nine carbon atoms (C9 to C12). Known globally under trade frameworks such as TOPSOL, KOCOSOL, and SOLVESSO, these high-boiling solvents are prized for their high solvency capabilities (indicated by high Kauri-Butanol values), stable evaporation rates, and high flashpoints that minimize fire risks in heavy-duty applications.
These solvents are essential across key chemical industries, including agrochemical emulsifiable concentrates (EC), specialized industrial coatings, synthetic printing inks, oilfield extraction additives, and heavy engineering cleaning matrices. In comparison to aliphatic alternatives, aromatic hydrocarbon systems provide significantly stronger dissolution profiles for synthetic resins, chlorinated rubbers, acrylics, and active pesticide ingredients, rendering them structurally indispensable.
| Product Grade | Carbon Range | Boiling Range (°C) | Flash Point (°C) | Core Applications |
|---|---|---|---|---|
| S100 (CAS 64742-95-6) | C9 - C10 Fraction | 160 - 180 | > 42 | Paints, Resin Blends, Process Inks |
| S150 (CAS 64742-94-5) | C10 Fraction | 180 - 210 | > 62 | Agrochemicals, Emulsifiers, Coatings |
| S150ND | C10 (Low Naph) | 183 - 208 | > 63 | Regulatory-Compliant Agro, Paints |
| S200 (CAS 64742-94-5) | C11 - C12 Fraction | 230 - 290 | > 100 | Oilfield Chemicals, Mining, High-temp Bake |
Founded in December 2004 with a registered capital of 60 million yuan, Shandong Saier Chemical Technology Development Co., Ltd. has established itself as an industry leader in manufacturing high-purity aromatic solvents and fine chemicals. Our production facility is located at No.207, WeiLiu Road, Qilu Chemical Industrial Park, Linzi, Zibo City, Shandong Province—positioning us at the heart of one of China's most advanced chemical clusters.
We operate with a robust production capacity of 720,000 tons per year. Our core product catalog features environmentally friendly high-boiling aromatic solvents (including S-100, S-150, S-150ND, S-180, and S-200), specialty heat transfer oils (such as L-QC320), durene, PVC plasticizers, and high-value fine chemical intermediates (including thiophene, 1,3-Cyclohexanedione, MIPK, TMOF, TMOA, HPA, and TMG).
By sourcing raw inputs from major petrochemical refiners like Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical, we ensure consistently stable feedstock chemistry. This secure supply chain guarantees that our final products maintain the structural purity and consistent boiling ranges required by our international clientele across Asia, Europe, the Americas, and Southeast Asia.
Leveraging Zibo's petrochemical ecosystem to deliver cost-effective and highly reliable chemical supply chains.
Situated in the Qilu Chemical Industrial Park, Zibo City, we share direct access to pipelines and immediate feedstock transfers from major refining groups. This proximity eliminates internal transport overheads and insulates production against feedstock volatility.
Our facility utilizes advanced continuous fractional distillation units, enabling the separation of narrow-cut aromatic fractions with high precision. This ensures stable flashpoints, consistent boiling curves, and reliable solvency strength (Kauri-Butanol value) for every batch.
By maintaining long-term purchasing agreements with industry giants like Sinopec and PetroChina, our feedstock undergoes rigorous pre-entry screening. This strategic raw material security prevents heavy metal contamination and maintains batch stability.
Ensuring cross-border compliance, chemical registry alignment, and robust safety protocols for seamless international delivery.
International chemical sourcing requires strict adherence to regional regulatory frameworks and safety standards. At Shandong Saier Chemical, we operate a dedicated compliance department that supports our global clients with the documentation and registration steps necessary to meet their local environmental laws.
Our production facilities operate under ISO 9001:2015 (Quality Management), ISO 14001:2015 (Environmental Management), and ISO 45001:2018 (Occupational Health and Safety) certifications, ensuring our processes align with the high standards expected by multinational buyers.
From modern agrochemical formulations to high-durability industrial coatings.
Aromatic Solvent S150 and S200 serve as key carriers for active pesticide ingredients in Emulsifiable Concentrates (EC), Emulsions in Water (EW), and Oil Dispersions (OD). They provide excellent solvency for active ingredients, high flashpoints for transport safety, and optimal emulsion stability in the field.
Widely utilized in automotive, marine, protective, and industrial coil coatings. The controlled evaporation rate of our S100 and S150 grades enables smooth film leveling, minimizes paint pinholes, and enhances gloss and adhesion on metal substrates.
These solvents are used as reaction media in polymer and resin synthesis, and as base components for specialized heat transfer oils (like L-QC320) that require excellent thermal stability at elevated operating temperatures.

Adapting to green chemistry directives, low-VOC requirements, and carbon reduction goals.
The global chemical industry is transitioning toward formulations with reduced environmental and occupational impacts. For aromatic solvent manufacturers, this has driven the development of low-naphthalene grades, where fractional crystallization and hydrotreating steps are used to lower naphthalene concentrations to negligible levels.
Additionally, optimizing heating and distillation energy efficiency is key to modern chemical plant management. By integrating heat recovery systems and digital control systems in our distillation towers, Shandong Saier Chemical has significantly reduced carbon emissions per ton of product, helping our customers meet their Scope 3 greenhouse gas reduction targets.
Research is actively exploring the synergy between high-solvency aromatic hydrocarbons and bio-based co-solvents (such as vegetable methyl esters). These hybrid systems maintain the dissolution capabilities of aromatics while lowering the overall volatile organic compound (VOC) profile, meeting the strict requirements of modern ecological labeling schemes in Europe and North America.
