Founded in December 2004, Shandong Saier Chemical Technology Development Co., Ltd. has established itself as an industry powerhouse. Headquartered at No.207, WeiLiu Road, Qilu Chemical Industrial Park, Linzi, Zibo City, Shandong Province, we operate inside one of China's most advanced chemical clusters, leveraging world-class regional infrastructure and strict compliance governance.
Backed by a solid registered capital of 60 million yuan, our enterprise began with high-volume production of fundamental chemical reagents. Over nearly two decades of strategic evolution, we have shifted our focus towards high-purity fine chemical materials, engineering a diversified catalog that feeds multiple advanced industrial supply chains.
Our raw feedstocks are secured directly from strategic petrochemical leaders including Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical. This guarantees pristine raw material integrity before manufacturing even begins. Operating at an annual capacity of 720,000 tons, our products support major industrial centers across Beijing, Shanghai, Tianjin, Hebei, Shandong, and Henan, while serving leading international markets in Asia, Europe, the Americas, and Southeast Asia.
Ethylene Glycol Dimethyl Ether (also known systematically as 1,2-dimethoxyethane, Monoglyme, or DME, CAS No. 110-71-4) is an exceptionally stable, clear, aprotic polar ether solvent. Chemically represented by the formula C4H10O2, Monoglyme stands out due to its unique structural properties: it features a high dipole moment combined with a low viscosity and excellent chelation capacity toward metallic cations. Unlike protic solvents, it does not possess reactive hydrogen atoms, making it highly compatible with strong bases, organometallic reagents, and reductive reaction environments.
For chemical synthesis engineers, Monoglyme is a superior alternative to traditional solvents like Tetrahydrofuran (THF) or Diethyl Ether, particularly when higher boiling points (85°C) and robust thermodynamic stability are required. It operates efficiently as a multi-dentate ligand, coordinating to metal ions to enhance the reactivity of Grignard reagents, metal hydrides, and organolithium compounds, thereby increasing overall reaction yield and reducing waste outputs.

China is now the undisputed global anchor for chemical manufacturing and infrastructure. Sourcing Ethylene Glycol Dimethyl Ether from premium Chinese factories like Shandong Saier offers dramatic operational advantages for international procurement offices:
The global demand for Ethylene Glycol Dimethyl Ether is scaling rapidly, driven by two key megatrends:
The Evolution of Lithium Battery Electrolytes: As the automotive industry shifts toward electric vehicles (EVs) and high-energy-density batteries, glyme solvents are receiving intense focus. DME serves as an essential co-solvent in lithium-sulfur (Li-S) batteries and silicon-anode lithium-ion batteries due to its low viscosity, high ionic conductivity, and electrochemical stability with lithium metal anodes. This battery revolution is driving the need for ultra-dry, battery-grade Monoglyme (<20ppm water content).
Modern Active Pharmaceutical Ingredient (API) Synthesis: In the pharmaceutical sector, regulatory bodies require higher synthesis purity and safer processes. DME is highly valued as a reaction solvent because it is easily recovered and exhibits excellent performance in low-temperature organometallic reactions (such as lithiation and boronation). This minimizes side-reactions and simplifies purification steps compared to conventional solvents.
To help global companies optimize their procurement and chemical workflows, Shandong Saier offers tailored solutions matching localized application scenarios:
Pharmaceutical Industry Solution: High-purity DME acts as a reaction solvent in the production of complex cardiovascular, antiviral, and oncological drugs. Our rigorous batch tracing and strict control over metal residues align with the high standards of international API producers.
Electronics and Semiconductor Solution: Utilized in photoresist stripping formulations and specialized precision cleaning operations, where low non-volatile residues (NVR) and high-purity organic systems are required.
Polymer Chemistry & Materials Science: Serves as an excellent polymerization solvent and plasticizer for specialized polymers, fluoroplastics, and advanced membrane fabrication processes.
Buying hazardous chemical raw materials like Ethylene Glycol Dimethyl Ether internationally requires high attention to compliance, packaging, and logistical safety. Sourcing teams should prioritize the following parameters:
Based in the Qilu Chemical Industrial Park, Zibo City, we are connected to China's leading chemical transport and supply network, ensuring consistent feedstock and fast logistics.
We source basic feedstocks directly from petrochemical giants like Sinopec, PetroChina, and Hengli Petrochemical, ensuring superior chemical stability at the source.
Recognized as a national high-tech enterprise, we invest heavily in process optimizations to maximize yield, reduce energy draw, and limit waste output.
From complex intermediates to aromatic solvents (S100, S150, S150ND, S180, S200), we support global chemical supply chains across multiple processing sectors.
Every shipment undergoes rigorous laboratory checks and GC testing, matching ISO-9001 quality specifications and environmental standards.
We manage complex cargo handling and sea freight procedures, safely transporting hazardous liquids (Class 3) to main global shipping terminals.
Monoglyme (DME) provides a higher boiling point (85°C) and flash point than Tetrahydrofuran (THF), enabling safer handling at elevated reaction temperatures. Additionally, its bidentate ether structure allows for stronger coordination to metal cations, which dramatically accelerates organometallic conversions like Grignard reactions and hydride reductions.
In lithium battery applications, even trace moisture (<50ppm) reacts with lithium anodes and electrolyte salts (e.g., LiPF6) to produce hydrofluoric acid (HF) and unwanted gas, degrading battery life and safety. Our battery-grade DME undergoes multi-stage molecular sieve dehydration to meet ultra-low moisture limits.
We maintain strict control over our raw material inputs by working directly with petrochemical leaders like Sinopec. In addition, our manufacturing facilities feature real-time process control (DCS systems) and specialized laboratory analyses (GC, Karl Fischer, ICP-MS) for every batch produced.
We offer specialized packaging configurations including UN-approved 180kg carbon steel drums and heavy-duty ISO Tanks for large bulk orders. As DME is a Class 3 hazardous liquid (UN 1155), we handle all dangerous goods documentation, custom declarations, and shipping arrangements through major ports like Qingdao.
