Leveraging continuous chemical engineering innovation and structural polycyclic platforms since 2004.
Founded in December 2004, Shandong Saier Chemical Technology Development Co., Ltd. (located at No.207, WeiLiu Road, Qilu Chemical Industrial Park, Linzi, Zibo City, Shandong Province) has established itself as an authoritative leader in the development, manufacture, and global export of refined polycyclic compounds, high-boiling aromatic solvents, and functional fine chemical intermediates. With a robust initial registered capital of 60 million yuan and an annual industrial output capacity reaching 720,000 tons, our organization is structured to bridge the gap between heavy primary refining streams and high-end molecular synthesis.
Our strategic operations are integrated with China's largest petrochemical refining conglomerates, including Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical. By using reliable C9, C10, and high-boiling aromatic cuts as direct feedstocks, we ensure high purity and continuous supply across our entire fine chemical and solvent lines.
In our early phase, our product roadmap specialized in environmentally compatible heavy aromatic solvents (under designations such as Solvent Naphtha, TOPSOL, KOCOSOL, and Solvesso equivalents) spanning S-100, S-150, S-150ND, S-180, and S-200. Concurrently, we established lines for secondary intermediates and performance materials, including high-efficiency Heat Transfer Oils (L-QC320), Durene, PVC plasticizers, Thiophene, 1,3-Cyclohexanedione, Methyl Isopropyl Ketone (MIPK), Trimethyl Orthoformate (TMOF), Trimethyl Orthoacetate (TMOA), Hypophosphorous Acid (HPA), and Tetramethyl Guanidine (TMG). These processes are supported by our national high-tech enterprise accreditation, driving industrial-scale supply to key domestic and international markets across the Americas, Europe, Asia, and Southeast Asia.

Analysing international shifts in high-purity polycyclic compound utilization and industrial applications.
The global market for polycyclic hydrocarbons, functional ring structures, and specialized aromatic solvents is undergoing a transformation. Historically valued primarily as high-temperature heat transfer fluids and basic paint thinners, these complex organic architectures are now central to modern material science, advanced microelectronics, and targeted agrochemical formulation.
In Europe and North America, strict environmental regulations (such as REACH and EPA mandates) have accelerated the demand for high-flashpoint, ultra-low naphthalene aromatic solvents. Solvents like S-150ND (Naphthalene Depleted), which retain their solvency power while keeping free naphthalene levels below 1% (and often below 0.1%), are replacing older, less-refined alternatives. This shift has created an export demand for manufacturers capable of performing high-resolution fractional distillation at scale.
Simultaneously, the expansion of the electronics manufacturing sector in Southeast Asia and East Asia has increased the consumption of polycyclic dianhydrides and cage-like hydrocarbons. Systems utilizing Pyromellitic Dianhydride (PMDA) are critical for creating polyimide films that can withstand the high processing temperatures of semiconductor packaging and flexible printed circuit boards. Similarly, adamantane derivatives (such as 1,3-Dimethyladamantane) serve as structural building blocks in photoresist formulations for deep UV lithography, highlighting the transition of these compounds from commodities to high-value specialties.
Process engineering of tricyclic structures, heteroaromatic rings, and heavy reformates.
Developing high-purity polycyclic and fine chemical intermediates requires a clear technological roadmap focused on catalytic selectivity and efficient thermal separation. Below is an outline of the chemical processes used at Shandong Saier Chemical to achieve high-purity outputs across our product catalog:
Tricyclic cage structures, such as 1,3-Dimethyladamantane (CAS: 702-79-4), are synthesized via the catalytic isomerization of hydrogenated cyclic dimers (like tetrahydrodicyclopentadiene). Operating under Lewis acid catalysts or specialized zeolite systems, we achieve precise rearrangement of the carbon skeleton to ensure thermodynamic stability, low volatile organic output, and high purity for lithographic and pharmaceutical uses.
By utilizing heavy C9-C11 aromatic reformates, our facility runs continuous multi-stage fractional distillation under vacuum. This separation isolates distinct boiling ranges while removing heavy residues and inorganic sulfur. For low-naphthalene grades (ND series), an additional extraction or catalytic hydrogenation step is integrated to selectively saturate naphthalene rings without reducing the aromaticity of the overall solvent matrix.
Our heterocyclic production lines, including Thiophene (CAS: 110-02-1) and 1,2,3-1H-Triazole (CAS: 288-36-8), utilize high-temperature gas-phase reactions or click-chemistry condensation pathways. Precise control over feed ratios and reactor temperature profiles reduces polymer byproduct formation, delivering clean building blocks for agrochemical and active pharmaceutical ingredient (API) manufacturing.
Operational stability through geographical integration, raw feedstock access, and logistics.
In the global chemical trade, supply chain reliability is as critical as chemical purity. Shandong Saier Chemical's main facility is located inside the Qilu Chemical Industrial Park in Linzi, Zibo City, Shandong Province. This location provides several strategic advantages for global buyers:
As part of our commitment to green manufacturing, our plant utilizes closed-loop VOC recovery systems and high-efficiency thermal oxidizers. This allows us to reuse waste heat from rectification columns, lowering our overall energy footprint and aligning with global ESG standards.

Examining how specific industries utilize our products in real-world formulations.
Understanding the final application context helps us optimize our products to meet specific customer requirements. Below are three case studies showing how our chemicals are used in target industries:
In regional crop protection, emulsifiable concentrates (EC) require solvents with high solvency power, low phytotoxicity, and high flashpoints for safe storage. Our Aromatic Solvent S-150ND provides a suitable solution. With its low naphthalene content, it enables formulators to meet EPA and European labeling standards while keeping active ingredients stable in solution, even during cold-weather storage.
The production of flexible electronic circuits relies on polyimide films made from Pyromellitic Dianhydride (PMDA). Producers in Korea, Taiwan, and Japan require PMDA with low moisture and iron content to prevent dielectric breakdown in microcircuits. Shandong Saier's purification processes yield high-grade PMDA that meets the requirements of cleanroom microelectronics manufacturing.
The rigid, cage-like structure of the adamantane ring is a key component in several antiviral and neurological drugs. Intermediates like 1,3-Dimethyladamantane serve as precursors for these drug APIs. Our synthetic control ensures low impurity levels, helping pharmaceutical synthesis laboratories streamline their downstream purification and crystallization processes.

Technical answers to common questions about our products, manufacturing, and shipping processes.
Standard Aromatic Solvent S-150 (CAS: 64742-94-5) contains naturally occurring naphthalene (typically 4% to 10% by weight) derived from C10 distillation cuts. The S-150ND (Naphthalene Depleted) version undergoes an additional process step to reduce the naphthalene content to under 1% (often below 0.1%). This helps customers comply with strict environmental and labeling regulations in markets like Europe and North America without significantly reducing the solvent's performance.
