Explore our high-performance organic synthesis intermediates, chemical structures, and optimized industrial formulations.
Aromatic hydrocarbons form the structural backbone of modern organic chemistry. Characterized by their planar, cyclic, conjugated systems obeying Hückel's Rule (4n + 2 π-electrons), these molecules exhibit significant thermodynamic stability. In industrial applications, modulating the substituents and side-chain configurations of the benzene ring allows for the customization of physical properties, including solubility profiles, boiling ranges, and reactivity parameters.
At Shandong Saier Chemical Technology Development Co., Ltd., we specialize in the continuous rectification and purification of complex aromatic systems. By isolating discrete alkylbenzene isomers and refining aromatic naphtha fractions, we supply the chemical industry with targeted solvent solutions such as S-100, S-150, S-150ND, S-180, and S-200. These products serve as essential media for printing inks, agricultural emulsifiable concentrates, and specialized industrial coatings.
Our raw materials are secured via deep strategic integrations with China's refinery giants, including Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical, ensuring trace stability and absolute consistency across multi-thousand-ton batches.
Utilizing high-efficiency distillation towers and precise temperature profiles to isolate target isomers like Durene (1,2,4,5-tetramethylbenzene) with minimal trace contaminants.
Engineering Naphthalene-Depleted (ND) aromatic solvents containing less than 0.1% naphthalene, meeting strict European and US safety and environmental standards.
Adjusting the carbon number distribution (C9 to C12+) to balance flash points, evaporation rates, and solvent power across demanding applications.
Located at the epicentre of the chemical manufacturing sector in China—No.207, WeiLiu Road, Qilu Chemical Industrial Park, Linzi, Zibo City, Shandong Province—our facility benefits from world-class logistical infrastructure and integrated utility networks. Since our founding in December 2004, our facility has expanded to a massive scale, boasting a consolidated production capacity of 720,000 tons per year.
Through our Factory 4.0 modernization initiative, we have transitioned our entire production scheme to Distributed Control Systems (DCS), integrating real-time gas chromatography with automated feeding loops. This ensures that whether we are distilling basic environmentally friendly high-boiling aromatic solvents (such as solvent naphtha, TOPSOL, KOCOSOL, TOLUENE AROMATIC HYDROCARBON, and NAFTA DISOLVENTE SOLVESSO) or manufacturing specialty chemicals like PMAD, 1,3-Cyclohexanedione, and L-QC320 heat transfer oil, our process parameters remain locked within tight deviation limits.

Our strategic proximity to major shipping ports (such as Qingdao Port) and state-of-the-art railway links within the Qilu Industrial Park allows us to mitigate supply chain disruptions. By maintaining deep storage tanks for both raw materials and finished products, we safeguard our global partners from market fluctuations and ensure stable contract deliveries even during peak demand cycles.
Aromatic hydrocarbons and their structural derivatives are integral to high-growth industrial sectors. Our technology roadmap focuses on moving up the value chain from basic solvent formulations to highly specialized molecular structures designed for advanced applications.
Specialized low-naphthalene S-150ND and S-200ND solvents serve as active ingredient carriers in emulsifiable concentrates (EC), ensuring optimal phytotoxicity profiles and chemical stability in cold storage conditions.
Using our high-purity Durene (1,2,4,5-tetramethylbenzene), manufacturers synthesize Pyromellitic Dianhydride (PMAD / PMDA), which is the precursor for polyimide (PI) films used in flexible circuits and electronic displays.
Our L-QC320 heat transfer oil is formulated using thermally stable alkylated aromatics, allowing for prolonged operation up to 320°C in closed-loop systems without thermal cracking or polymerization.
As the global chemical industry transitions toward carbon neutrality, Shandong Saier Chemical is investing in research pathways for bio-based aromatic solvents and catalytic processes that reduce energy intensity. By utilizing advanced zeolite catalysts (including zeolite rotor technologies for VOC concentration and recovery), we are minimizing emission footprints during raw material processing, aligning our factory footprint with modern ESG requirements.
Explore our clean-room laboratories, synthesis facilities, and logistics centers that enable us to ship internationally to regions including Asia, Europe, the Americas, and Southeast Asia.
Navigating global chemical regulations requires rigorous documentation and transparent analytical data. As an established exporter, Shandong Saier Chemical provides comprehensive regulatory support for importers across North America, Europe, and Asia Pacific markets.
We ensure that our export shipments, particularly heavy aromatic solvents and complex intermediates, are fully documented with updated Safety Data Sheets (SDS) conforming to the Globally Harmonized System (GHS). We actively support our customers with REACH pre-registration and registration dossiers for bulk solvent volumes imported into the EU.
Whether shipping via Iso-Tanks, 200L steel drums, or specialized IBC containers, we comply with strict International Maritime Dangerous Goods (IMDG) standards. Our automated drumming and loading terminals minimize moisture pickup and cross-contamination during transit, safeguarding purity levels from our factory to your processing plant.
Expert answers regarding chemical specifications, structures, sourcing, and logistics.
The distinction lies in their carbon number distribution and boiling ranges. S-100 consists primarily of C9 hydrocarbons with a boiling range of 150-180°C. S-150 consists primarily of C10 hydrocarbons with a boiling range of 180-210°C, and S-200 contains C11-C12+ fractions, which provides a higher flash point and a boiling range above 220°C.
We employ advanced fractional crystallization and deep rectification processes to separate naphthalene from the C10 and C11 fractions. This reduces the naphthalene concentration in our S-150ND and S-200ND solvents to under 0.1% (often below gas chromatography detection limits), which satisfies strict environmental and occupational health standards.
Durene undergoes oxidation to form Pyromellitic Dianhydride (PMDA/PMAD). PMDA is a highly symmetrical tetracarboxylic acid dianhydride. When reacted with diamines, it forms polyimide (PI) resins known for their high thermal stability, chemical resistance, and dielectric properties, which are critical in high-end electronics.
We maintain long-term supply agreements with leading petrochemical producers in China, including Sinopec and PetroChina. This direct pipeline minimizes raw material price volatility and ensures that our refining capacity of 720,000 tons per year remains consistent and uninterrupted.
Yes, our R&D center works with international buyers to adjust flash points, viscosity levels, and solvency parameters (Kauri-Butanol values) to meet specific application requirements in paints, agricultural formulations, and chemical intermediates.
