Diisopropyl ether (also known as DIPE or Isopropyl Ether, CAS Number: 108-20-3) is a high-value secondary ether that plays a critical role in modern industrial chemical separation, synthesis, and formulation. As a specialized solvent, DIPE offers a unique set of properties, including a boiling point of 68.5°C, high volatility, and significantly lower solubility in water compared to other ether solvents like diethyl ether or tetrahydrofuran (THF). These physical characteristics make it an exceptional agent for extraction processes, crystallization, and organic synthesis.
Shandong Saier Chemical Development Co., Ltd., as a leading international developer and supplier of fine chemical products, maintains rigorous manufacturing standards to ensure the highest purity profiles. Typically, industrial applications require DIPE at a minimum purity of 99.0% (Tech Grade) and up to 99.7% or higher (Pharmaceutical/Reagent Grade). By controlling trace water content (<0.05%) and implementing advanced stabilization configurations (utilizing non-interfering food-grade and industrial-grade stabilizers such as BHT to prevent dangerous peroxide accumulation), Shandong Saier provides reliable and highly stable ether products to global markets.
The global demand for Isopropyl Ether is structurally linked to expansion in high-precision processing industries. In the pharmaceutical sector, DIPE is utilized as a reaction and crystallization solvent for the synthesis of active pharmaceutical ingredients (APIs), hormones, and peptides. Due to its hydrophobic nature, DIPE enables clean phase separation, resulting in high API yields and minimum impurity profiles during batch crystallizations.
In the petrochemical and fuel sectors, DIPE represents a high-octane blending component due to its high octane blending value (RON approx. 110) and low vapor pressure. While historically MTBE occupied significant volume in gasoline blending, DIPE presents an ecologically viable, low-water-solubility alternative, which reduces groundwater contamination concerns. Additionally, in the coatings, resins, and metallurgy industries, DIPE is used for extracting rare metals and acting as a coupling agent for resin formulations.
Ensures low moisture contamination, narrow crystal size distribution, and efficient removal of unwanted reaction byproducts.
Highly effective for extracting phenols, organic acids, and specialty metals from complex aqueous processing matrices.
The commercial synthesis of Isopropyl Ether is primarily accomplished via two primary chemical pathways:
As a leading manufacturer, Shandong Saier utilizes advanced continuous distillation technology to optimize energy efficiency and purity yields. Our processing towers are designed with state-of-the-art automation controllers that continuously monitor trace compounds, separating water-DIPE and IPA-DIPE azeotropes to produce high-specification output for demanding applications.
Founded in December 2004, Shandong Saier Chemical Technology Development Co., Ltd. has established a formidable presence in the global chemical landscape. Located strategically at No. 207, WeiLiu Road, Qilu Chemical Industrial Park, Linzi, Zibo City, Shandong Province, China, the company is built on a solid foundation of 60 million yuan in registered capital.
From its inception, Shandong Saier focused on high-performance industrial chemicals, starting with environmentally friendly high-boiling aromatic solvents (including Solvent Naphtha, TOPSOL, KOCOSOL, Aromatic Hydrocarbons, Toluene Aromatic Hydrocarbons, and Solvesso variants like S-100, S-150, S-150ND, S-180, and S-200), alongside Heat Transfer Oils L-QC320, durene, PVC plasticizers, and intermediates such as thiophene, 1,3-Cyclohexanedione, MIPK, TMOF, TMOA, HPA, and TMG.
Leveraging raw materials sourced reliably from major national and global refining and aromatic centers including Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical, the company maintains absolute quality control at the source. Currently operating with a robust total production capacity of 720,000 tons per year, Shandong Saier serves prominent domestic hubs (Beijing, Shanghai, Tianjin, Hebei, Shandong, Henan) and exports extensively to key international markets in Europe, the Americas, Asia, and Southeast Asia.
Exporting Class 3 Flammable Liquids requires rigorous adherence to logistics and safety regulations. Shandong Saier provides complete localized support, covering dangerous goods documentation, UN-approved steel drum packaging, and specialized ISO tanks.
We adhere strictly to international safety and quality standards, including REACH registration for European exports, TSCA compliance for American distributions, and GHS-compliant SDS documentation. Our localized logistics networks guarantee timely customs clearance and terminal delivery in major ports worldwide.
With modern industry leaning heavily towards carbon footprint reduction and green chemistry, Shandong Saier is continually investing in optimization processes. Our research and development center focuses on reducing energy consumption in the distillation of high-purity solvents. Additionally, we are looking forward to developing bio-derived raw materials to produce green-indexed DIPE, assisting global corporations in reaching their environmental, social, and governance (ESG) goals.
A visual tour through our advanced manufacturing facility, modern laboratories, and office environment.
How high-purity Isopropyl Ether optimizes processes in leading industries globally.
Reagent Grade DIPE acts as an elite mobile phase modifier and extraction media, delivering stable baselines and avoiding solvent-column interactions.
Due to its high chemical stability, DIPE serves as an inert, high-boiling solvent environment for organometallic reactions like Grignard reagents.
Our DIPE formulations are treated with optimized amounts of stabilizers to suppress autoxidation mechanisms, ensuring long-term storage safety.
Technical insights regarding the handling, storage, and procurement of Isopropyl Ether.
DIPE has a higher boiling point (68.5°C vs 34.6°C) and lower vapor pressure, which reduces solvent evaporation loss during reaction processes. Additionally, DIPE is significantly less soluble in water, making it a superior choice for liquid-liquid extraction with minimal phase mixing.
To prevent dangerous peroxide accumulation caused by exposure to oxygen, we package DIPE under a nitrogen blanket and offer configurations containing stabilizers such as Butylated Hydroxytoluene (BHT) or other specialized inhibitors. We also suggest testing and replenishing stabilizer packages if solvents are stored for extended periods.
Our DIPE is typically packed in UN-approved steel drums (150kg/drum) or high-capacity ISO tanks (approx. 14,000kg to 20,000kg per tank). All logistics comply with IMDG Code regulations for Class 3 hazardous materials.
Yes, our production plants operating under the 720,000-ton capacity layout conform strictly to ISO 9001 and ISO 14001 guidelines. For pharmaceutical clients, we provide detailed product documentation including certificate of analysis (COA), residual solvent reports, and heavy metal profiles.
