Explore our premium grade chemical specialties engineered for complex synthesis, polymerization, and high-efficiency thermal management.
Assessing the molecular structural advantages, synthesis pathways, and macro applications in the modern chemical landscape.
In the contemporary specialty chemicals market, Aromatic Ethers and their corresponding high-boiling aromatic solvents represent a critical class of materials required for advanced polymer chemistry, electronic coatings, high-performance agrochemicals, and thermal engineering. As industries shift toward stringent green chemistry guidelines and search for optimized VOC (Volatile Organic Compound) profiles, the demand for high-purity, tailor-made OEM formulations has surged globally.
This document details the technological milestones, raw material sourcing structures, manufacturing excellence, and global compliance frameworks established by Shandong Saier Chemical Technology Development Co., Ltd. As a pioneer with decades of operational data, we present this comprehensive white paper to provide deep scientific insights and support procurement heads and research scientists in selecting the ideal solvents and intermediates for their proprietary chemical processes.
Founded in Zibo City, Shandong Province, delivering world-class chemical intermediates since 2004.
Shandong Saier Chemical Technology Development Co., Ltd. has embarked on an impressive journey since its establishment in December 2004. Situated at No. 207, WeiLiu Road, Qilu Chemical Industrial Park, Linzi, Zibo City, Shandong Province, the company has continuously evolved and thrived in the highly competitive chemical industry. With a registered capital of 60 million yuan, the company laid a solid financial foundation to build, maintain, and expand highly sophisticated refining systems.
In our early stages, the production focused on basic chemical products, establishing reliability in highly volatile markets. The initial product lineup included environmentally friendly high-boiling aromatic solvents (Solvent naphtha, TOPSOL, KOCOSOL, Aromatic Hydrocarbon, TOLUENE AROMATIC HYDROCARBON, NAFTA DISOLVENTE SOLVESSO) such as S-100, S-150, S-150ND, S-180, and S-200, Heat transfer oils L-QC320, and other main Intermediate products along with products like durene, PVC plasticizers, thiophene, 1,3-Cyclohexanedione, MIPK, TMOF, TMOA, HPA, and TMG.
These premium materials were mainly sourced from major state-of-the-art refineries and aromatic plants, including Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical. By leveraging these highly reliable, top-tier raw material sources, the company ensured product quality and chemical consistency right from the molecular input stage. At that time, the production capacity reached an outstanding 720,000 tons per year, supplying crucial domestic markets in Beijing, Shanghai, Tianjin, Hebei, Shandong, and Henan, alongside corporate accounts at Sinopec and PetroChina. Over the years, this domestic footprint paved the way to expand seamlessly to global markets, including regions such as East Asia, Europe, North America, South America, and Southeast Asia.
Deploying aromatic solvents and ethers to drive efficiency, safety, and performance across core global sectors.
High-purity solvents like S-150 and S-200 with low naphthalene content are critical for EC, EW, and SC crop protection products. They maximize active ingredient solubility while minimizing phytotoxicity.
Our aromatic solvent series delivers optimal evaporation rates, excellent solvency power, and superior surface tension control, which are vital for automotive OEM coatings, coil coatings, and marine protective paints.
Synthesizing and refining Heat Transfer Oil L-QC320 provides systems with exceptional thermal stability at temperatures exceeding 300°C. It minimizes carbon deposits and maintains heat transfer efficiency over extended lifespans.
How Saier Chemical achieves high purity levels in C9, C10, and C12+ aromatic fractions through continuous fractional distillation.
The core of our aromatic solvent production relies on continuous rectification technology. Sourced directly from modern petrochemical plants, the raw heavy C9 and C10 streams undergo multi-stage fractional distillation under precise vacuum and temperature controls. By systematically adjusting reflux ratios, we separate narrow-boiling cuts to produce solvents with targeted flashpoints, evaporation rates, and solubility parameters.
Below is a typical specification overview of our primary refined solvent naphtha products:
| Product Name | CAS Registry Number | Boiling Range (°C) | Flash Point (PMCC, °C) | Aromatic Content (vol%) | Primary Applications |
|---|---|---|---|---|---|
| Aromatic Solvent S100 | 64742-95-6 | 160 – 180 | ≥ 40 | ≥ 99.0 | Industrial paints, resin synthesis, agrochemical ECs |
| Aromatic Solvent S150 | 64742-94-5 | 180 – 210 | ≥ 62 | ≥ 99.0 | Pesticide emulsifiability, baking finishes, printing inks |
| Aromatic Solvent S150ND | 64742-94-5 | 180 – 210 | ≥ 63 | ≥ 99.5 (Naph < 1%) | Eco-friendly agrochemicals, consumer products |
| Aromatic Solvent S200 | 64742-94-5 | 230 – 290 | ≥ 100 | ≥ 99.0 | High-boiling printing inks, oilfield recovery fluids |
In addition to standard distillates, Shandong Saier Chemical has optimized the production of S150ND (Naphthalene Depleted). High levels of naphthalene are increasingly restricted by regulatory bodies globally due to toxicity concerns. Through secondary separation processes, we reduce the naphthalene content of our solvents to below 1.0 wt% (and even below 0.1 wt% on custom configurations). This ensures compliance with EU REACH and US EPA standards without compromising solvency power.
Meeting international quality guidelines while developing sustainable manufacturing processes.
As the years passed, Shandong Saier Chemical Technology Development Co., Ltd. recognized the critical importance of innovation and technological advancement. We invested significantly in research and development to optimize production efficiency, enhance product purity, and develop environmentally friendly products. In response to the growing global demand for energy-saving processes, we optimized our plants to reduce carbon footprint and minimize VOC emissions. This dedication earned us recognition as a **National High-Tech Enterprise**, bringing policy support and cementing our brand value.
Our global operations are backed by rigorous adherence to chemical safety and compliance guidelines:
A strategic vision for advanced molecule synthesis, bio-based aromatics, and automated petrochemical production.
Our forward-looking technology roadmap is built on three main pillars: **purity enhancement**, **bio-derived alternatives**, and **production automation**. By upgrading our separation towers with state-of-the-art structured packings and automated control loops, we aim to offer ultra-pure specialty cuts tailored for pharmaceutical and electronic-grade solvents. Additionally, we are researching bio-derived raw materials to eventually introduce bio-aromatic solvents with low carbon footprints.
Furthermore, our digital transformation strategy incorporates real-time analytical monitoring (using online chromatography and spectroscopic sensors) to ensure that every batch of solvent leaving Zibo meets exact customer specifications. This continuous investment ensures that Shandong Saier Chemical remains at the forefront of the global chemical supply chain, adapting to changing environmental and technical standards.
Providing clear, expert answers regarding aromatic solvents, synthesis customization, compliance, and logistics.
The difference lies in their distillation cuts. S100 consists primarily of C9 aromatics with a boiling range of 160-180°C and a flashpoint around 40°C. S150 contains mostly C10 aromatics with a higher boiling range of 180-210°C and a higher flashpoint (≥ 62°C), making it safer for high-temperature drying applications.
We use advanced secondary vacuum fractional distillation towers. By isolating and extracting the naphthalene-heavy fractions, we lower the naphthalene content of our solvents to under 1.0 wt% (or under 0.1 wt% on demand), helping clients comply with strict global safety standards.
We maintain long-term, direct procurement agreements with major petrochemical complexes, including Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical. This guarantees high quality and a stable, uninterrupted supply chain.
