Premium functional monomers, specialized solvents, and high-purity synthesis intermediates designed for industrial excellence.
A comprehensive analysis of heavy aromatic hydrocarbons in modern industrial manufacturing, environmental alignment, and formulation dynamics.
In modern industrial synthesis and formulation chemistry, the demand for highly efficient, heavy aromatic hydrocarbon solvents has grown exponentially. Standard solvents often fall short in applications requiring high boiling points, low volatility, and elevated solvency power. This is where Arosol 150 (Aromatic Solvent S150) and its naphthalene-depleted counterpart, Arosol 150ND (S150ND), play a vital role.
Characterized by a complex mixture of C10-C12 aromatic hydrocarbons, these solvents exhibit a distillation range typically between 180°C and 210°C. With a high Kauri-Butanol (KB) value, they excel at dissolving resins, polymers, active agrochemical ingredients, and heavy organic structures. This solvency efficiency enables thinner film forming in coatings, more stable emulsified systems in agrochemicals, and superior extraction capabilities in industrial processes.
The global market for aromatic solvents is highly dynamic, driven by infrastructural developments in emerging economies and regulatory shifts in established markets. Europe, North America, Asia-Pacific, and South America represent the largest clusters of demand. Manufacturers must navigate supply chains that bridge large petro-chemical refineries with specialized processing units.
Shandong Saier Chemical Technology Development Co., Ltd. sits at the heart of this global ecosystem. Our high-capacity production units process raw feeds sourced from major domestic and global refineries. This integration ensures a reliable flow of materials even during volatile market cycles. From agricultural emulsifiable concentrates (EC) in Latin America to high-temperature baking enamels in East Asia, Saier's aromatic solvents form the backbone of multiple critical supply lines.
Furthermore, logistical resilience through dedicated ISO tank fleets, regional drumming facilities, and strategic chemical park positioning allows us to guarantee reliable delivery windows across continents, ensuring zero downtime for continuous process manufacturing lines.
Founded in December 2004, Shandong Saier Chemical Technology Development Co., Ltd. has established itself as an industry pioneer in Zibo City, Shandong Province. Strategically located within the Qilu Chemical Industrial Park (No. 207, WeiLiu Road, Linzi), Saier Chemical leverages state-of-the-art infrastructure and rich industrial networks. Our initial registered capital of 60 million yuan served as a solid financial foundation that enabled rapid scaling and heavy investment in fractionation and purification technologies.
In our early stages, our operations focused on producing basic chemical products. The original product lineup included environmentally friendly high-boiling aromatic solvents (such as Solvent Naphtha, TOPSOL, KOCOSOL, Aromatic Hydrocarbons, Toluene Aromatic Hydrocarbon, and Nafta Disolvente Solvesso) covering S-100, S-150, S-150ND, S-180, and S-200, alongside key products like durene, Heat Transfer Oils L-QC320, PVC plasticizers, thiophene, 1,3-Cyclohexanedione, MIPK, TMOF, TMOA, HPA, and TMG.
These feedstocks were sourced from premium refineries and petrochemical complexes, including Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical. This rigorous quality selection from the start laid the groundwork for our current 720,000 tons/year production capacity. Today, our footprint extends far beyond domestic hubs like Beijing, Shanghai, Tianjin, Hebei, Shandong, and Henan, reaching global markets in Asia, Europe, the Americas, and Southeast Asia.
Recognizing the fast pace of the global chemical industry, Shandong Saier Chemical Technology Development Co., Ltd. has continuously prioritized research, development, and environmental safety. By optimizing catalytic systems, distillation techniques, and separation cycles, we have systematically reduced energy consumption and production emissions, earning recognition as a national high-tech enterprise.
Our research teams collaborate with chemical research institutes to develop high-performance alternatives that support the global green transition. This includes upgrading our distillation towers to improve the precision of cut separations for Naphthalene-Depleted (ND) solvents and refining heat transfer efficiencies through advanced oil formulations like L-QC320.

Detailed analysis of our heavy aromatics fractions, including S100 and related fine chemical intermediates.
Produced from premium raw C10 aromatics using continuous fractionation and separation technologies. Aromatic Solvent S100 is a colorless, transparent, and highly aromatic organic solvent complying with international standards for hydrocarbon solvents. It features an evaporation rate suited for coatings and high-solids paints, ensuring excellent surface finish and film uniformity.
Our product portfolio also includes high-performance synthetic intermediates. These are raw materials for systemic crop protection agents, polymer catalysts, and thermal fluids. By maintaining raw material integration with major petrochemical facilities, we provide consistent purity profiles and low moisture content, which is crucial for sensitive reaction pathways.
Aligning product performance with regional standards, environmental safety, and specialized industrial sectors.
In global agricultural markets, S150 and S150ND are preferred carrier solvents for emulsifiable concentrates (EC). S150ND, with low naphthalene content, helps formulate products that avoid hazard label classifications while maintaining active ingredient solubility.
Arosol solvents offer high solubility for alkyds, acrylics, epoxies, and polyurethane resins. Their high boiling points and slow evaporation rates help control paint flow and leveling in industrial stoving enamels, automotive primers, and coil coatings.
These solvents are used in oilfield chemical formulations as demulsifiers, wax dispersants, and corrosion inhibitors due to their high flash points and low freezing points. Their thermal stability also supports specialized industrial extraction processes.
The following table outlines the physical and chemical profiles of Aromatic Solvent S150 & S150ND, highlighting the high solvency and purity achieved through our advanced processing techniques:

Developing low-carbon solutions and high-efficiency processes for tomorrow's chemical markets.
We are upgrading our fractionation systems to recover waste heat, aiming to reduce energy intensity and the carbon footprint of our solvent production.
Our R&D team is refining crystallization and extraction steps to produce Arosol 150 with less than 0.05% naphthalene, addressing strict consumer safety requirements.
We are researching the integration of renewable, plant-derived esters with heavy aromatics to create hybrid solvents that combine high solvency with improved renewability.
Technical answers to common questions about heavy aromatic solvent chemistry, transport, and regulatory compliance.
The distinction lies in the naphthalene content. Standard S150 contains naturally occurring naphthalene (typically 6-10 wt%), which requires warning labels. S150ND (Naphthalene Depleted) goes through a separation step to reduce naphthalene to below 1.0 wt% (or below 0.1 wt%), minimizing labeling requirements and environmental impact while maintaining similar physical properties and solvency.
Aromatic Solvent 150 has a flash point above 62°C (144°F), placing it in the combustible category rather than flammable under GHS. This relatively high flash point provides processing safety, making it suitable for high-temperature formulations and reducing fire protection requirements compared to low-flash solvents like xylene.
They should be stored in carbon steel or stainless steel tanks equipped with nitrogen blankets to minimize moisture ingress and oxidation. Seals and gaskets should be made of fluoropolymers (such as Viton or PTFE), as standard nitrile or neoprene rubbers will swell and degrade when exposed to aromatic hydrocarbons.
Yes, Shandong Saier Chemical provides full regulatory compliance. Our products, including S100, S150, and S150ND, are backed by EU REACH registration (and similar regional chemical inventories like TSCA and IECSC). We provide comprehensive Safety Data Sheets (SDS) and Certificates of Analysis (CoA) with every shipment.
The KB value of Arosol 150 is approximately 95, indicating strong solvency power. It reflects the solvent's ability to dissolve heavy polymers, resins, and active ingredients relative to standard reference materials. High KB values allow formulators to use less solvent to achieve the target viscosity.
