In the domain of heavy industrial hydrocarbons, Aromatic 200 Solvent (predominantly classified under CAS No. 64742-94-5) stands as the gold standard for high-boiling aromatic organic compounds. Comprising mainly of alkylbenzenes and heavier C10-C13 naphthenic-aromatic structures, it is a high-density, low-volatility fluid celebrated for its exceptional solvency, slow evaporation rate, and high flash point. These attributes make it irreplaceable in demanding downstream applications such as systemic agrochemical emulsifiable concentrates (EC), specialized automotive bake-coatings, and refinery process chemicals.
For procurement directors and research chemists, selecting a dependable OEM Aromatic 200 manufacturer is not merely about finding a vendor; it is about establishing a strategic partnership with an enterprise that controls high-precision fractional distillation systems and maintains deep raw material partnerships. High boiling point aromatic solvents (frequently marketed under brand names like Solvesso 200, TOPSOL, or KOCOSOL) require specialized molecular-cut control systems during production to ensure that heavy polycyclic aromatic hydrocarbons (PAHs), such as naphthalene, are carefully managed according to regional environmental requirements. This level of technical complexity dictates the operational framework of leading chemical manufacturers globally.
With environmental protection regulations like REACH in Europe and the EPA rules in the United States tightening constraints on volatile emissions, industrial buyers are prioritizing Aromatic 200 ND (Naphthalene Depleted) grades. Standard Aromatic 200 typically contains 6% to 10% naphthalene. Depleted grades bring this down to under 0.9% or even 0.1%, ensuring compatibility with eco-labeling requirements without compromising the solvency power (KB value) of the fluid.
To assist chemical engineers in assessing thermodynamic behaviors and formulation compatibility, we provide the technical profile comparing Standard Aromatic 200 and Naphthalene Depleted (ND) formulations below:

Founded in December 2004 with a registered capital of 60 million yuan, Shandong Saier Chemical Technology Development Co., Ltd. has established itself as an elite pioneer in the high-boiling aromatic solvents industry. Located at No.207, WeiLiu Road, Qilu Chemical Industrial Park, Linzi, Zibo City, Shandong Province, the company leverages Zibo's historic status as a cornerstone of China's petrochemical refining capabilities.
In our early operations, our production facility built strong distribution channels for core high-boiling aromatic solvents, including S-100, S-150, S-150ND, S-180, and S-200, alongside high-efficiency Heat Transfer Oils (such as L-QC320) and specialized intermediates (including Pyromellitic Acid/PMA, Durene, PVC plasticizers, thiophene, 1,3-Cyclohexanedione, MIPK, TMOF, TMOA, HPA, and TMG). By utilizing high-purity feedstock pipelines from Tier-1 national refineries such as Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical, we guarantee robust molecule stability and minimal sulfur content. Operating with an annual production capacity of 720,000 tons, Saier Chemical serves the domestic industrial hubs of Beijing, Shanghai, Tianjin, Hebei, Shandong, and Henan, while exporting to major chemical distributors and enterprises in Asia, Europe, the Americas, and Southeast Asia.
High-boiling solvent separation requires advanced thermal equipment and strict environmental controls. Shandong Saier Chemical operates a state-of-the-art facility incorporating high-vacuum fractional distillation columns, computerized DCS control centers, and strict emission scrubbers, which have earned the company national high-tech enterprise recognition.
In the globalized chemical supply chain, China's manufacturing clusters provide unique structural advantages. Selecting an OEM Aromatic 200 supplier situated in Zibo's Qilu Chemical Industrial Park delivers three distinct benefits to international procurement operations:
By establishing direct pipeline connections and strategic supply contracts with major domestic refiners like Sinopec and PetroChina, Saier Chemical secures a stable flow of high-purity C10+ heavy aromatic distillate feeds. This limits the pricing volatility common in isolated chemical operations.
OEM customization depends on modern distillation control. Whether your application requires an exact evaporation rate, specific flash points for high-temperature coating bakes, or ultra-low naphthalene content (ND grades) to comply with international regulations, our advanced towers deliver narrow-cut fractional isolation.
Saier Chemical's proximity to Qingdao Port enables efficient logistics handling. Our chemical export infrastructure is equipped to manage bulk ISO tank containers, standard 200L steel drums, or IBC totes, supported by custom hazard certification processing for hassle-free customs clearance.
The performance of Aromatic 200 Solvent stems from its high boiling range (230°C - 290°C) and KB value of 95. Below are the primary industrial areas where these attributes add substantial value:
In modern agriculture, crop protection chemicals require a highly active, stable carrier system. Active ingredients (such as systemic fungicides, pyrethroid insecticides, and selective herbicides) are often insolvable in water. Aromatic 200 serves as the primary hydrophobic solvent in Emulsifiable Concentrates (EC) and Microemulsions (ME). Its low volatility prevents premature crystallization of the active ingredient at the spray nozzle, ensuring even agricultural application under high-temperature environments.
Industrial baking coatings require a controlled, slow evaporation profile to prevent surface pinholes and blistering. Aromatic 200's distillation curve ensures a smooth paint film during high-temperature thermal curing. The high solvency helps dissolve acrylic, alkyd, and polyurethane resins, providing high gloss, level finishes, and excellent mechanical adhesion in coil coatings and automotive paints.
At high depths, crude oil extraction is challenged by heavy asphaltene and paraffin deposits. Aromatic 200 acts as an efficient carrier for corrosion inhibitors, demulsifiers, and flow-assurance additives. Its high flash point reduces combustible gas hazards on offshore platforms, while its high aromaticity enables it to keep heavy petroleum molecules in a stable colloidal state.
Due to its high boiling point and excellent thermal stability, Aromatic 200 is used as a reaction medium in chemical syntheses, such as in the manufacturing of plasticizers, dye intermediates, and specialized resins. This allows reactions to run at elevated temperatures under atmospheric pressure, reducing equipment complexity.
The global hydrocarbon solvents market is undergoing a major transition toward sustainability. Manufacturers are investing heavily in low-VOC formulations and naphthalene-depleted solvents (ND). Regulatory bodies like ECHA (European Chemicals Agency) and EPA continue to lower limits for hazardous air pollutants (HAPs). Saier Chemical remains ahead of this curve by utilizing high-precision fractionation technology to offer low-naphthalene options (S-150ND and S-200ND) to global distributors.
Beyond regulatory compliance, modern formulation facilities are seeking ways to optimize their carbon footprint. Utilizing heavy aromatic solvents with higher flash points reduces the need for explosion-proof transport and storage, lowering handling costs. Additionally, the high energy efficiency of modern Chinese petrochemical integration ensures that the raw materials used in our plants have a lower carbon footprint compared to older, isolated refining facilities.
Optimize your formulation stability, ensure regulatory compliance, and secure supply chain consistency with Shandong Saier Chemical's 720,000-ton annual capacity.
