Diethylene glycol dimethyl ether

Diethylene glycol dimethyl ether (DEGDME) is an important member of the ethylene glycol dimethyl ether family. It is renowned for its high boiling point (~162°C), high flash point (~57-70°C), wide liquid range, and excellent chemical and electrochemical stability. It can effectively solvate alkali metal ions and exhibits outstanding stability towards strong basic organometallic reagents (such as Grignard reagents, organic lithium). These properties make it the preferred solvent for cutting-edge applications that aim for high operational safety, high-temperature reaction conditions, long-lasting process duration, and high-voltage electrochemical window.

Product Description

Anhui Eapearl Chemical Co., Ltd., as a professional supplier in the fields of specialty chemicals and high-purity solvents in China, relying on advanced production purification technology and strict quality management system, now offers the market high-purity and high-performance diethylene glycol dimethyl ether (DEGDME). We are committed to transforming this top-notch non-protonic polar solvent, which has high boiling point, high flash point, wide electrochemical window and excellent chemical stability, into a key enabling material for achieving technological breakthroughs and process optimization in next-generation high-security batteries, high-end organic synthesis and precision manufacturing and other fields. 

Product Core Positioning 

Diethylene glycol dimethyl ether (DEGDME) is an important member of the ethylene glycol dimethyl ether family. It is renowned for its high boiling point (~162°C), high flash point (~57-70°C), wide liquid range, and excellent chemical and electrochemical stability. It can effectively solvate alkali metal ions, and exhibits outstanding stability towards strong basic organometallic reagents (such as Grignard reagents, organic lithium). These properties make it the preferred solvent for cutting-edge applications that aim for high operational safety, high-temperature reaction conditions, long-lasting process duration, and high-voltage electrochemical window.

Core application value and solutions 

Key solvent for the new generation of high-security battery electrolyte: As the core solvent or key additive for the electrolytes of lithium-sulfur batteries, sodium-ion batteries, potassium-ion batteries, and high-pressure lithium-metal batteries, DEGDME, due to its high boiling point providing high thermal stability, high flash point ensuring high operational safety, and its excellent solubility and inhibition effect on polysulfides, can significantly enhance the cycle life, capacity retention rate, and high-temperature safety of the batteries. Its wide electrochemical window (up to over 4.3V) enables it to be compatible with higher-voltage cathode materials, making it one of the key materials for developing battery systems with high energy density, long cycle life, and high safety. 

High-end organic synthesis and pharmaceutical research: In Grignard reactions, organic lithium/sodium reactions, anionic polymerization, coordination polymerization, and various condensation and alkylation reactions that require high-temperature conditions, DEGDME is an ideal high-boiling-point non-polar reaction medium. It can effectively stabilize active metal-organic reagents, increase reaction rates and yields, and due to its high boiling point, allows reactions to proceed at higher temperatures to accelerate kinetics. It is widely used in the synthesis of pharmaceutical intermediates, pesticide raw materials, and high-performance polymers (such as SBS, polyurethanes). 

Special industrial cleaning and electronic chemicals: Thanks to its strong dissolving power, high boiling point (low volatility), and low residue properties, high-purity DEGDME can be used for long-term precise cleaning in the manufacturing processes of semiconductor chips, display panels, and precision instruments, effectively removing residual photoresist, resin, grease, and soldering flux, meeting the strict requirements of high-end manufacturing for process windows and cleanliness. 

Gas purification and special functional fluids: Due to their selective physical absorption capabilities for acidic gases (such as H₂S, CO₂), they can be used as efficient absorbents in processes such as natural gas desulfurization and syngas purification, featuring large absorption capacity and low regeneration energy consumption. Additionally, they can also be used to prepare special high-temperature heat-conducting fluids or hydraulic fluids. 

High-end coatings, inks and resin processing additives: As high-boiling-point solvents, they can be used in special coating and ink formulations that require slow evaporation to achieve a smooth coating. In resin synthesis, they can be used as reactive solvents or leveling aids to improve system compatibility and reduce processing viscosity. 

Anhui Eapearl Chemical Co., Ltd., with high-end specialty solvents such as diethylene glycol dimethyl ether (DEGDME), has always focused on the demands of cutting-edge technology and precision manufacturing. We are not only a supplier of raw materials, but also a reliable partner for you to overcome technical challenges and achieve product innovation. Choosing us means choosing professionalism, safety and excellence.

Plak een reeks herhaalde metingen (CSV of één getal per regel). De calculator berekent het gemiddelde, de standaardafwijking en 95% CI, en detecteert uitschieters (Grubbs + Dixon Q).

Scheidingsteken: komma, spatie, tab, nieuwe regel. Minimaal 3 metingen.
📐 Statistische formules
  • x̄ = Σxᵢ / n — rekenkundig gemiddelde
  • s² = Σ(xᵢ - x̄)² / (n-1) — steekproefvariantie
  • s = √s² — standaardafwijking
  • RSD% = (s / x̄) × 100% — relatieve standaardafwijking
  • CI₉₅ = x̄ ± t(0.05, n-1) × s / √n — Student's t
  • G = |xᵢ - x̄| / s — Grubbs-test
  • Q = |xsuspect - xnearest| / |xmax - xmin| — Dixon Q-test

The Hansen parameters fall outside the range of the method, so the distance Ra cannot be calculated, and the database holds no solubility measurement to put in its place. Rather than eleven ratings with nothing behind them, we show none. Base the solvent choice on the safety data sheet and on experimental data.

Why Acetonitrile vs Methanol?
PropertyAcetonitrile (ACN)Methanol (MeOH)
Viscosity (20°C)0.37 cP0.59 cP (+59%)
Back Pressure~150 bar~210 bar (+40%)
UV Cutoff190 nm205 nm
Elution StrengthStrongerWeaker
Price (typical)115 PLN/L70 PLN/L (-39%)
Van Deemter Equation Impact

H = A + B/u + Cu

Higher viscosity (MeOH) → lower optimal flow rate → longer runtime.

Buffer Selection: Why NH₄HCO₃?
  • Volatile: MS-compatible (evaporates without residue)
  • pH range: 6.5–8.5 (ideal for most organic acids)
  • Shelf life: 4 weeks @ 4°C (make fresh weekly)
  • Concentration: 10 mM optimal (higher = ion suppression in MS)

Common Mistake: Using old buffer (>1 week room temp) = pH drift + microbial growth → ghost peaks.

Gradient Problem From The Lab

Stability studies — forced degradation

5 degradation conditions (acidic / alkaline / oxidation / light / temperature). You must separate all degradation products.

Our Gradient Strategy

  • Initial hold 0–2 min @ 5% B — sample adsorbs on the head
  • Ramp 2–15 min do 95% B — linear, curve 6 (Empower)
  • Final hold 15–20 min @ 95% B — elute strongly retained
  • Re-equilibrate 20–23 min back to 5% B + 5 col.volumes

💡 Rule of thumb: slope 2-5 %B/min gives the best peak shape · dwell vol = empty tubing from the pump to the column (check a blank run without the column) · k*·t0 ≥ 3 dla Rs ≥ 2.0.

Snyder-Dolan LSS Model

Log k = log kw − S·φ, gdzie φ = fraction B. Optymalny gradient: Δφ ≈ 0.6–0.8 per 5 t0. Dla kolumny 250×4.6mm @ 1 mL/min → t0 ≈ 2 min → gradient 10–12 min.

Particles >0.22 μm clog the column inlet frit. Pressure rises +50 bar per 100 injections. Column lifetime drops from 2000 to 500 injections. Filter cost: 2 PLN. Column cost: 1800 PLN.

10 columns in 2 months — wrong filter

Marta K., QC supervisor, pharma company 2025-02-10 Poziom 4/5
Wat er gebeurde:

Q1 audit: column cost +340% vs Q4. QA blamed the lab. Investigation: a new operator was using a 0.45 μm filter instead of 0.22 μm. Microparticles got through the guard and were killing the main columns by the 100th injection.

💡 Lekcja:

The filter SOP must be WRITTEN and checked every batch. 0.22 μm is the standard per USP . Cost of the error: 10 columns × 1800 PLN = 18,000 PLN + audit finding.

Peak tailing ruined my results

Anna K., PhD student, Warszawa 2024-03 Poziom 3/5
Wat er gebeurde:

I ran the method exactly as written. Main peak Tf = 2.8 (should be <1.5). Integration impossible. I repeated it 6× — always tailing.

💡 Lekcja:

Causes: (1) buffer pH 8.2 instead of 7.0, (2) 2-month-old buffer (bacteria!), (3) C8 column instead of C18. Fix: fresh buffer pH 7.0 + switch to C18 → Tf 1.2, Rs 1.9→2.3.
