Engineered high-purity aromatics, complex intermediates, and specialized chemical syntheses serving global manufacturing hubs.
In the fields of industrial chemistry, petrochemical refinement, and high-performance solvent manufacturing, the term C9 Hydrocarbon refers to a complex stream of volatile organic compounds containing nine carbon atoms. Depending on the distillation temperature, feedstock source, and refining method, these fractions are processed into high-boiling aromatic solvents, synthetic petroleum resins, or specialty chemical intermediates. For global procurement officers, chemists, and paint manufacturers, identifying the correct C9 Hydrocarbon Name and CAS registry parameters is critical to ensuring raw material compatibility and meeting rigorous regulatory benchmarks.
At Shandong Saier Chemical Technology Development Co., Ltd., founded in December 2004, we specialize in separating, refining, and reforming heavy aromatic fractions into industry-standard solvents and intermediates. Operating within the prestigious Qilu Chemical Industrial Park (Zibo City, Shandong Province), we maintain a total processing capacity of 720,000 tons per year. We leverage direct feedstock channels from petrochemical giants like Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical to guarantee product stability and consistent quality across all production batches.
Information Gain Insight: The commercial success of C9 hydrocarbon applications depends heavily on the distillation range and the exact isomer distribution. Commercial C9 aromatic solvents mainly consist of Trimethylbenzenes, Methylethylbenzenes, Indene, and Propylbenzenes. The presence and concentration of these specific molecules determine critical parameters such as the Kauri-Butanol (Kb) value, evaporation rate, and flash point.
Advancing from crude catalytic reforming fractions to ultra-low naphthalene green solvents and hydrogenated specialties.
Our facility utilizes state-of-the-art continuous vacuum distillation and column separation systems. This technology enables the precise fractionation of raw C9 and C10 hydrocarbon feedstocks into targeted aromatic solvents like S100 and S150, maintaining narrow boiling ranges and uniform solvent properties.
Global environmental regulations demand the reduction of hazardous air pollutants. Shandong Saier Chemical has optimized catalytic hydrogenation and advanced crystallization setups to produce Aromatic Solvent S150ND (Naphthalene Depleted), reducing naphthalene content to below 1% or even under 0.1%, matching EU and North American agrochemical standards.
Our R&D division works on developing low-VOC formulations and bio-based co-solvents. By integrating renewable chemical streams with traditional petroleum hydrocarbons, we aim to reduce the overall carbon footprint of industrial solvents without compromising on high solvency or film-forming characteristics.

Our journey from a local solvent manufacturer in Zibo City to a global supplier of fine chemical intermediates.
Established in December 2004 with a registered capital of 60 million yuan, Shandong Saier Chemical Technology Development Co., Ltd. has grown alongside China's modern petrochemical industry. Located at No. 207, WeiLiu Road, within the Qilu Chemical Industrial Park (Linzi District, Zibo City, Shandong Province), we benefit from close proximity to major pipelines and refining facilities, which supports our raw material logistics. Our initial operations focused on basic chemical formulations, but we quickly transitioned to high-value-added specialties.
In our early stages, our product portfolio centered around environmentally friendly high-boiling aromatic solvents (including Solvent naphtha, TOPSOL, KOCOSOL, Aromatic Hydrocarbons, and Solvesso equivalents) such as S-100, S-150, S-150ND, S-180, and S-200. We also developed intermediate products like durene, PVC plasticizers, thiophene, 1,3-Cyclohexanedione, MIPK, TMOF, TMOA, HPA, and TMG, alongside high-stability heat transfer oils such as L-QC320. By establishing long-term procurement partnerships with top-tier producers like Sinopec, PetroChina, and ChemChina, we secured high-grade feedstock streams for our processes. Today, our 720,000-ton annual production capacity serves both domestic industrial centers (Beijing, Shanghai, Tianjin, Hebei, Shandong, Henan) and international markets across Asia, Europe, the Americas, and Southeast Asia.
How our location in the Qilu Chemical Industrial Park optimizes production cost, shipping logistics, and raw material access.
Industrial chemical manufacturing requires stable logistics and strict safety systems. Shandong Saier Chemical operates under China's "Factory 4.0" framework. Our production units are monitored by Distributed Control Systems (DCS) to manage temperature, pressure, and flow rates during fractionation. This automated approach limits batch-to-batch variation, which is a key requirement for international paint, polymer, and crop protection clients.
Our location in Zibo City, Shandong Province, provides direct integration with regional refining pipelines. By receiving feedstocks directly from Sinopec Qilu Petrochemical and nearby refining complexes, we reduce raw material transport costs and emissions. In addition, our close proximity to Qingdao Port allows us to coordinate container and ISO tank shipping, helping to manage delivery lead times to global destinations.
How our products support key industrial, agricultural, and technological sectors globally.
Active ingredients in pesticides often require highly soluble carriers. Our Aromatic Solvent S100 and S150 fractions provide high solvency for organic actives. For regions with strict environmental controls, our low-naphthalene S150ND helps formulators meet safety standards while keeping active ingredients in solution.
C9 hydrocarbons serve as solvents in architectural coatings, stoving enamels, and automotive primers. Their balanced evaporation rates allow the wet paint film to level properly, preventing bubbles, orange peel effects, or surface pinholes. This is essential for high-durability marine and industrial finishes.
Fractions of C9 containing indene, methylindene, and vinyltoluenes are polymerized into C9 petroleum resins. These resins are used as tackifiers in hot-melt adhesives, printing inks, and rubber compounding. In addition, our intermediates serve in the synthesis of specialized PVC plasticizers.
Compliance & Safety Assurance: Shandong Saier Chemical provides full safety data sheets (SDS) and regulatory documentation (including REACH, GHS, and regional environmental declarations) to simplify integration into international supply chains.
Technical answers regarding product chemistry, specifications, logistics, and compliance.
From a chemical nomenclature perspective, C9 hydrocarbons include several isomers: Trimethylbenzenes (such as pseudocumene, mesitylene, and hemimellitene), Methylethylbenzenes (ortho, meta, and para isomers), Propylbenzenes (n-propylbenzene and isopropylbenzene/cumene), and Indene. These molecules have different boiling points and evaporation rates, but they all share high aromatic content and strong solvency.
Standard Aromatic Solvent S150 typically contains between 5% and 10% naphthalene by weight, which is naturally present in high-boiling aromatic fractions. S150ND (Naphthalene Depleted) goes through an extra separation step to reduce naphthalene content below 1.0% (and often below 0.1%). This helps clients comply with environmental regulations and labeling rules in markets like the EU and USA.
We source high-purity C9/C10 reformate and aromatic streams from large refining complexes, including Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical. These feedstock partnerships help us maintain stable operations and consistent product quality throughout the year.
We offer flexible packaging to suit different logistics setups, including standard 200L steel drums (containing 180kg-190kg net), 1000L IBC tanks, and bulk ISO tanks. For international shipments, we handle export logistics from Qingdao Port under FOB, CFR, or CIF terms, ensuring compliant dangerous goods handling.
Our facility runs on automated Distributed Control Systems (DCS) to manage temperature profiles, distillation rates, and pressure. We also test each production run using gas chromatography (GC) and mass spectrometry (MS) in our on-site lab to confirm purity, distillation range, and moisture levels before shipment.
