Triethyl Citrate (TEC) / 트리에틸 시트레이트 CAS 77-93-0

FAQ - 기술 및 공급 관련 문의

• 질문:

  트리에틸 시트레이트와 에틸 시트레이트는 같은 에스테르인가요?

  답변: 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.
• 질문:

  What are the typical physical properties of Triethyl Citrate?

  답변: 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.
• 질문:

  산업용 트리에틸 시트레이트를 구매할 때 어떤 사양이 중요한가요?

  답변: 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.
• 질문:

  What applications require a technical or compendial standard?

  답변: 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.
• 질문:

  트리에틸 시트레이트를 대량으로 납품하기 전에 무엇을 확인해야 할까요?

  답변: 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.
