Direct export-grade fine chemicals and processing inputs compliant with global industrial benchmarks.
In the arena of global chemical synthesis, Benzene and Toluene function as the primary structural pillars for a vast range of downstream derivatives. These molecules, derived from the complex catalytic reforming and steam cracking of petroleum fractions, are engineered into solvents, polymer precursors, fine chemical intermediates, and agricultural raw materials. In China, the integration of large-scale refining facilities has elevated the domestic chemical manufacturing capacity, positioning manufacturers like Shandong Saier Chemical Technology Development Co., Ltd. at the vanguard of the international supply market.
As industrial applications continue to demand tighter purity margins and reduced environmental footprints, the technological infrastructure of Chinese factories has shifted from simple petrochemical extraction to advanced fractional purification and selective chemical synthesis. This shift is critical for supplying key compounds, including environmentally friendly high-boiling aromatic solvents (under designations such as TOPSOL, KOCOSOL, and Solvesso) and fine chemical intermediates.
The production of aromatic solvent fractions, such as S-100, S-150, S-150ND, S-180, and S-200, depends on the precise distillation of C9 to C10+ aromatic streams. These streams are byproduct lines of aromatic plants operated by giants like Sinopec and PetroChina. By utilizing continuous fractional columns, factories isolate narrow-boiling-point solvents designed for specialized industrial roles:
A quantitative view of our refining footprint and supply security metrics.
Founded in December 2004 with a solid financial foundation built on a registered capital of 60 million yuan, Shandong Saier Chemical Technology Development Co., Ltd. has established a strategic operational footprint at No. 207, WeiLiu Road, within the Qilu Chemical Industrial Park, Linzi, Zibo City, Shandong Province. Over the last two decades, the company has grown from a basic domestic supplier into a technologically advanced manufacturer of aromatic solvent lines, fine chemicals, and chemical intermediates.
Initially, our operations focused on the production of essential chemical products and high-boiling aromatic solvents, including S-100, S-150, S-150ND, S-180, and S-200, alongside Heat transfer oils L-QC320. By building strong partnerships with top-tier domestic refineries and aromatic plants—such as Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical—we established high reliability in feedstock quality right from our early stages. Our early capacity reached 720,000 tons per year, supplying key industrial zones across Beijing, Shanghai, Tianjin, Hebei, Shandong, and Henan. Over time, these logistics networks expanded globally, serving major markets in Asia, Europe, the Americas, and Southeast Asia.
Our expanded portfolio now covers a wide variety of specialized chemical intermediates, including **durene (1,2,4,5-tetramethylbenzene), PVC plasticizers, thiophene, 1,3-cyclohexanedione, Methyl Isopropyl Ketone (MIPK), trimethyl orthoformate (TMOF), trimethyl orthoacetate (TMOA), hypophosphorous acid (HPA), and tetramethylguanidine (TMG)**. This diverse product lineup allows us to serve multiple industrial sectors, including polyurethane manufacturing, agrochemical formulation, electronics processing, and high-performance polymer synthesis.
Examining the structural, geographical, and technological factors that drive our competitive position.
Direct pipeline connections and structural partnerships with major refineries, including Sinopec and PetroChina, secure consistent raw materials even during market fluctuations.
Located inside the Qilu Chemical Industrial Park in Zibo, Shandong, our facility benefits from integrated utility systems, waste treatment infrastructure, and direct access to major shipping ports.
Our advanced fractional distillation columns allow us to adjust boiling ranges and lower naphthalene content (below 0.1%) to comply with strict international regulatory standards.
Our facility utilizes modern Distributed Control Systems (DCS) to monitor temperatures, pressures, and flow rates in real time, ensuring consistent batch quality.
We support international buyers with complete documentation, including safety data sheets (SDS) and REACH registration support, ensuring smooth customs clearance.
With an annual capacity of 720,000 tons, our facilities easily scale up production to handle high-volume procurement and long-term supply agreements.
An inside look at our manufacturing facilities, offices, and processing units in Shandong.
Environmental and occupational safety regulations are driving changes in the industrial solvents market. Traditional volatile aromatic solvents are increasingly being replaced by high-flashpoint alternatives with narrow boiling ranges. Products like **Aromatic Solvent S-150ND** and **S-200** are designed to meet these needs, offering excellent solvency with a reduced environmental impact. Our research and development efforts focus on lowering naphthalene content to under 0.1% using specialized extraction processes, ensuring these products remain compliant with evolving international trade requirements.
In the agricultural sector, C9 and C10 aromatic solvents are widely used to dissolve active ingredients in emulsifiable concentrates (ECs) and emulsion in water (EW) formulations. These solvents provide excellent dissolution capability for a broad range of pesticides, herbicides, and fungicides. Using high-purity solvents prevents recrystallization during storage in colder climates, helping agricultural distributors maintain product stability over long periods.
Modern coatings require solvents that support smooth application and consistent leveling. Our aromatic solvents are optimized for compatibility with alkyd, acrylic, epoxy, and polyurethane resins. By managing solvent evaporation rates, industrial finishers can achieve high-quality surface finishes free from defects like pinholes or orange-peel textures.
Industrial manufacturing relies heavily on dependable heat management. Our **Heat Transfer Oil L-QC320** is formulated to offer high thermal stability and oxidation resistance in closed-loop heating systems. Capable of operating efficiently at temperatures up to 320°C, it helps prevent carbon deposit formation, extending system lifetimes and reducing maintenance costs for processing facilities.
How our chemistry portfolio supports key industrial sectors around the world.
We supply naphthalene-depleted solvents (S-150ND) that dissolve high-concentration active pesticide ingredients while meeting strict environmental standards.
High-purity solvents like S-100 and S-150 help manufacturers control drying profiles and improve coating finish quality.
We produce critical intermediates, including Durene, Thiophene, and MIPK, for the synthesis of pharmaceuticals, dyes, and performance polymers.
Detailed technical answers regarding quality standards, logistics, and product specifications.
The primary difference lies in the naphthalene content. Standard S-150 can contain up to 8% to 10% naphthalene by weight. Our S-150ND (Naphthalene Depleted) is processed through a secondary extraction stage that reduces naphthalene levels to less than 1.0% (often below 0.1%). This is particularly important for agrochemical producers exporting to markets with strict ecological regulations regarding groundwater protection.
We locate our operations directly inside the Qilu Chemical Industrial Park in Zibo, Shandong. This position allows us to secure raw materials directly from large-scale refining facilities, including Sinopec and PetroChina. These close relationships provide a stable feedstock supply and help minimize price and volume volatility.
Under normal operating conditions at or below 320°C in a properly designed, closed-loop thermal fluid system, our L-QC320 oil is formulated to provide long-term service. Its stability is supported by high-quality hydrogenated base oils and thermal stabilizer additives that resist thermal cracking and oxidation, helping minimize the need for system flushes.
