Diethyl carbonate

Diethyl Carbonate (DEC, CAS 105-58-8) is a high-purity, eco-friendly organic compound known as a “green solvent” with low toxicity and good biodegradability. It appears as a colorless transparent liquid with molecular formula C₅H₁₀O₃ and molecular weight 118.13, featuring a density of 0.975 g/mL at 20 °C, melting point -43 °C, boiling point 126-128 °C, and flash point 31 °C (closed cup).

As a key component in lithium-ion battery electrolytes, DEC enhances low-temperature performance and electrochemical stability when blended with other carbonates like EC and DMC. It also acts as an efficient alkylating and carbonylating agent in pharmaceutical and chemical synthesis, supporting the production of intermediates, polycarbonates, and fine chemicals while reducing reliance on toxic reagents. In coatings, inks, and cleaning formulations, DEC serves as a low-VOC solvent with excellent dissolving capacity, improving product safety and environmental compatibility.
Our DEC is offered in industrial, battery, and pharmaceutical grades, backed by a stable supply chain and full compliance documentation, meeting international quality standards for reliable performance across diverse industrial applications.

Product Description

Diethyl Carbonate (DEC, CAS 105-58-8) is a high-purity, eco-friendly organic compound classified as a “green solvent,” characterized by low toxicity, good biodegradability, and stable chemical properties.

 It appears as a colorless transparent liquid with a molecular formula of C₅H₁₀O₃ and a molecular weight of 118.13, with a density of 0.975 g/mL at 20 °C, a melting point of -43 °C, a boiling point of 126-128 °C, and a closed-cup flash point of 31 °C.

 Available in industrial, battery, and pharmaceutical grades, our DEC is produced under strict quality control, supported by a stable supply chain and complete compliance documents to meet international standards for diverse industrial applications.

As a key component in lithium-ion battery electrolytes, DEC is blended with other carbonates such as EC and DMC to enhance the battery’s low-temperature performance and electrochemical stability, extending cycle life and improving safety. 

It also acts as an efficient alkylating and carbonylating agent in pharmaceutical and chemical synthesis, used to produce intermediates, polycarbonates, and fine chemicals while reducing reliance on toxic reagents.

 In coatings, inks, and cleaning formulations, DEC serves as a low-VOC solvent with excellent dissolving power, effectively replacing harmful traditional solvents to boost product safety and environmental compatibility.

 For usage, it is handled under dry, well-ventilated conditions in battery manufacturing, employed under controlled temperature and pressure in chemical reactions, and applied directly or diluted in industrial cleaning processes.

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

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.

Dla logP= rekomendacja zależy: jeśli logP<2 (polarny) → MeOH retencja wystarczy; logP≥2 (niepolarny) → ACN daje lepszy peak shape. Dla tej molekuły (MW=118.13, CAS 105-58-8) zaczynaj od ACN w gradiencie 5→95% B.

Gradient Problem From The Lab

Selectivity by changing the buffer

You have 3 critical peak pairs. Phosphate pH 3 gives Rs=1.4. You need to reach 2.0. Change the pH or the buffer type?

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.

Linear = płynne odklejanie związku od kolumny = lepszy peak shape (Tf < 1.3). Step gradient daje shock waves = artifacts.

Why does my chromatogram look like a cardiogram?

The baseline jumps ±10 mAU, you see peaks but also „humps" between them. Integration is impossible.

Alternative Detectors

  • RID — for compounds without UV absorbance (sugars, polymers). Sensitivity x1000 lower.
  • ELSD — uniwersalny, ale destroys sample (niezgodny z MS).
  • LC-MS/MS — LOD 1 pg, strukturalna potwierdzenie via MRM.

Validation Reality Check

Method transfer from Warsaw to Krakow failed

At first we ran it in the Warsaw lab. Transfer to Kraków: every Rt shifted +0.8 min, Rs borderline at 1.9-2.1. Investigation: buffers from different manufacturers (Merck vs Sigma-Aldrich) differed by 0.2 in pH. 6 weeks of transfer revalidation.
Lesson learned (R&D team, 2 sites, 2025-09-18):
Transfer requires a SPEC for the buffer (manufacturer, grade, LOT). Not just „NH4HCO3 10 mM pH 7.0". Run a preliminary system suitability on the new instrument before the full transfer.

Dla API (active pharmaceutical ingredient) typowo 98-102% label claim. Dla diethyl carbonate (CAS 105-58-8) sprawdź: (1) USP monograph jeśli istnieje, (2) kompendium pharmacopoeia wewnętrzna, (3) ICH Q6A dla specyfikacji nowych substancji. Related substances ≤0.10% per ICH Q3A.

Source: ICH Q6A

USP : Rs ≥ 2.0. Fix: (1) wolniejszy gradient +30%, (2) niższy flow 0.8 mL/min, (3) dłuższa kolumna 250mm, (4) niższa temp 20°C.

Prep Mistakes That Ruined The Run

What is „system suitability" and do I have to do it?

The teacher said „run an SST". You have no idea what that is. The USP method has a checklist — 4 parameters. Which are critical?

Sample Prep Protocol

  1. Dissolve 10 mg of sample in 10 mL of mobile phase (initial composition)
  2. Sonikuj 5 min → vortex 30 s
  3. Filtruj 0.22 μm PTFE (nie PVDF — adsorbuje!)
  4. Transfer 1 mL do HPLC vial z septum PTFE/silikon
  5. Przechowuj 4°C max 48h

Why Filter 0.22 μm?

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.

Incorrect integration — publication rejected

Kasia M., PhD Analytical Chemistry, UJ 2025-06-03 Poziom 4/5
Wat er gebeurde:

Submission to JPBA. Reviewer 2: „Peak at 12.4 min shows manual integration, but baseline slope suggests co-elution". I had to revalidate the whole method. 3 months of delay.

💡 Lekcja:

Manual integration = a red flag for reviewers. Solve CO-ELUTION in methods dev, not in integration. Optimise the gradient instead of force-fitting the peak.

Method transfer from Warsaw to Krakow failed

R&D team, 2 sites 2025-09-18 Poziom 5/5
Wat er gebeurde:

At first we ran it in the Warsaw lab. Transfer to Kraków: every Rt shifted +0.8 min, Rs borderline at 1.9-2.1. Investigation: buffers from different manufacturers (Merck vs Sigma-Aldrich) differed by 0.2 in pH. 6 weeks of transfer revalidation.

💡 Lekcja:

Transfer requires a SPEC for the buffer (manufacturer, grade, LOT). Not just „NH4HCO3 10 mM pH 7.0". Run a preliminary system suitability on the new instrument before the full transfer.
