Product Description
Triethyl citrate
Recognized names: Triethyl citrate; Citric acid triethyl ester; Triethyl 2-hydroxypropane-1,2,3-tricarboxylate; TEC
CAS Number: 77-93-0
EINECS Number: 201-070-7
Formula: C₁₂H₂₀O₇
Molar mass: 276.28 g/mol
Appearance: clear, colourless liquid with a mild odour; confirm colour and grade-specific limits on the offered specification.
Reference density: about 1.137 g/cm³ at 20 °C. Confirm the value, test conditions and offered grade in the current TDS.
Phase transition: reference melting or freezing point is near -55 °C; confirm the method and offered grade in the current TDS.
Reference boiling point: about 287-294 °C at atmospheric pressure. Confirm the value, test conditions and offered grade in the current TDS.
Reference flash point: about 151-155 °C. Confirm the value, test conditions and offered grade in the current SDS.
Vapour pressure is low at ambient temperature; use the current SDS for the applicable value, method and handling assessment.
Freezing behaviour is grade- and method-dependent; use the same current TDS value applied to the low-temperature phase-transition specification.
Reference refractive index: about 1.445. Confirm the value, test conditions and offered grade in the current TDS.
Solubility: moderately soluble in water and miscible with common alcohol or ether solvents; formulation compatibility must be confirmed in the buyer’s system.
Product use: citrate plasticizer, solvent or carrier in selected polymer and formulation systems. Food, pharmaceutical or personal-care suitability requires the matching grade, specification and regulatory documents; it is not established by the chemical name alone.
FAQ - Technical & Supply Chain
-
Q:
Are Triethyl Citrate and Ethyl Citrate the same ester?
A: Yes. Triethyl citrate, ethyl citrate and citric acid triethyl ester identify CAS 77-93-0. They are not acetyl triethyl citrate or tributyl citrate. The order should state TEC, the CAS number, ester assay and the intended plasticizer, coating or formulation use. -
Q:
What are the typical physical properties of Triethyl Citrate?
A: Triethyl citrate is normally a clear, colourless liquid with a mild odour. Reference values include density about 1.137-1.144 g/cm3 at 20 degrees C, freezing point around -55 degrees C, boiling point about 287-294 degrees C, flash point roughly 151-160 degrees C and refractive index about 1.440-1.446. Confirm the value and test conditions for the offered grade. -
Q:
Which specifications matter when purchasing industrial Triethyl Citrate?
A: Agree ester assay, water, acidity, colour, density, refractive index and nonvolatile residue with the test methods. Plasticizer and coating users may also set limits for free citric acid, ethanol and trace metals. Water and acidity are usually critical because they can affect ester performance and formulation stability. -
Q:
What applications require a technical or compendial standard?
A: Triethyl citrate is used in plasticizers, coatings, inks and formulation systems where low odour and controlled volatility can be important. Food, flavour, pharmaceutical or cosmetic use requires a matching compendial or regulated standard, while general plasticizer use may accept a technical grade with agreed assay, acidity, water, colour and impurities. -
Q:
What should be confirmed before bulk Triethyl Citrate delivery?
A: Confirm drum, IBC or tanker format, container compatibility, quantity, previous cargo and unloading connection. Keep the ester sealed and protected from contamination, follow the applicable storage-temperature range, and state whether the shipment is technical or compendial grade.
