Explore our primary chemical series sourced and manufactured through rigorous purification standards to fulfill precise downstream criteria.
In the domain of high-performance aromatic compounds, 1-Tetramethylbenzene (commonly referred in industrial contexts as 1,2,4,5-tetramethylbenzene or Durene, CAS 95-93-2) represents a foundational chemical intermediate. Its symmetrical molecular structure lends unique properties, rendering it highly sought after for the synthesis of Pyromellitic Dianhydride (PMDA), which serves as the critical building block for Polyimide (PI) films.
The production of industrial-grade 1-tetramethylbenzene requires sophisticated fraction separation due to the presence of closely boiling isomers, such as 1,2,3,5-tetramethylbenzene (Isodurene) and 1,2,3,4-tetramethylbenzene (Prehnitene). High-quality manufacturers employ high-efficiency fractional crystallization and continuous superfractionation techniques to ensure a purity level exceeding 98.5%. The high freezing point of the 1,2,4,5-isomer (79.2°C) compared to its liquid isomer counterparts forms the physical foundation of modern crystallization processes.
Through state-of-the-art catalytic systems, suppliers can selectively isomerize C10 aromatic streams sourced from steam crackers and reformates, driving up the yield of the highly valued symmetrical isomer and reducing the downstream environmental footprint.

Shandong Saier Chemical Technology Development Co., Ltd. has established itself as an authoritative hub for high-boiling aromatic solvents and chemical intermediates.
Founded in December 2004 with a solid financial baseline of 60 million Yuan in registered capital, Shandong Saier Chemical Technology Development Co., Ltd. began its journey at No.207, WeiLiu Road, Qilu Chemical Industrial Park, Linzi, Zibo City, Shandong Province. Strategically located within one of China's most advanced chemical clusters, the enterprise leverages immediate access to robust infrastructure and premier feedstocks.
In its initial phase, Saier Chemical prioritized the refining and processing of raw aromatics sourced from industry giants like Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical. With an initial processing capacity of 720,000 tons per year, we specialized in high-performance solvents including S-100, S-150, S-150ND, S-180, and S-200.
Over the two decades of development, the company evolved into a national high-tech enterprise, expanding its production focus to high-value-added crystalline intermediates like Durene (1-tetramethylbenzene fractions), Heat Transfer Oils (L-QC320), PVC plasticizers, thiophene, 1,3-Cyclohexanedione, Methyl Isopropyl Ketone (MIPK), TMOF, TMOA, HPA, and TMG.
Established in Zibo City, Shandong, focusing on core aromatic refining with a capacity of 720,000 tons per year and supplying local domestic hubs in Beijing, Shanghai, Tianjin, and Hebei.
Optimized manufacturing chains to produce specialized solvents and fine chemical compounds, transitioning into global export markets across Asia, Europe, and America.
Recognized as a National High-Tech Enterprise, marking major milestones in energy-saving setups, green crystallization units, and process intelligence.
Fully compliant with international chemical regulatory frameworks (REACH, ISO9001, GHS), supplying ultra-pure isomers to the modern microelectronics and polymer sectors.
By partnering with nearby refining giants such as Sinopec, PetroChina, and ChemChina, Shandong Saier ensures a continuous supply of C9 and C10 aromatic feedstocks, shielding buyers from sudden raw material volatility.
Operating from Zibo City, Shandong, gives our production lines direct proximity to major chemical shipping ports (Qingdao, Tianjin). This significantly lowers overland logistics costs and reduces shipment lead times.
Our plants are equipped with high-tech separation chambers, continuous analytical laboratories, and automatic filling systems, optimizing yield and quality while minimizing manual errors.
Transparent looks into our state-of-the-art facilities located at the Qilu Chemical Industrial Park, Zibo City.
Our ultra-pure 1-tetramethylbenzene is oxidized to form Pyromellitic Dianhydride (PMDA). PMDA is the essential monomer used in producing flexible copper clad laminates (FCCL) and insulation films for aerospace wiring, demanding raw materials with low trace metal impurities.
With modern regulations restricting chlorinated hydrocarbons, C10-based isomers serve as base materials for high-flashpoint aromatic solvents (S-150ND and S-200). These are widely utilized in automotive coatings and premium agricultural formulations.
Symmetrical aromatics offer high thermal stability. We convert them into heat transfer oil formulations (like L-QC320) which operate effectively at high temperatures in synthetic textile plants and chemical production reactors without thermal cracking.
Navigating chemical shipping requires reliable quality control systems and full documentation for complex global borders.
To support international enterprises, Shandong Saier Chemical maintains active regulatory compliance frameworks across multiple jurisdictions. Our export shipments of 1-tetramethylbenzene, aromatic solvents, and functional intermediates are accompanied by full GHS-compliant Safety Data Sheets (SDS), REACH certifications for the European Union market, and ISO 9001/14001 quality and environmental management system standards.
For localized support, our dedicated logistics team works with top-tier global shipping lines to offer bulk vessel transport, ISO tanks, and steel drum packaging. We guarantee traceability, offering batch-by-batch Certificate of Analysis (COA) reports verified through gas chromatography (GC) and mass spectrometry (MS) systems at our modern testing lab.
