⚗️ Chemical & Physical Properties
Triethyl citrate is a colorless, clear liquid with a faint, sweet odor. It is commonly used as a flavoring agent in food products due to its pleasant scent.
The molar mass of Triethyl citrate is approximately 276.28 g/mol, and it has a density of about 1.135 g/cm³. This puts its molar mass in line with common food items such as sugars, and its density is similar to that of vegetable oils.
Triethyl citrate has a melting point of around -43°C and a boiling point of about 294°C. These properties make it distinct from many common food items, as sugars typically have higher melting points, and oils have lower boiling points.
Triethyl citrate is soluble in water at lower concentrations and exhibits low viscosity. This differs from many common food items, as sugars are highly soluble in water and have a high viscosity, while oils typically have low solubility in water and low viscosity.
🏭 Production & Procurement
Triethyl citrate is typically produced through the esterification reaction of citric acid with ethanol. This process is commonly carried out under reflux conditions with the presence of a catalyst, such as sulfuric acid. The resulting product is then purified through distillation and filtration.
Triethyl citrate can be procured from various chemical suppliers or manufacturers. It is commonly available in both liquid and solid forms, depending on the specific application. Transportation of Triethyl citrate is typically done in sealed containers to prevent leakage and ensure product integrity.
The procurement of Triethyl citrate may involve ordering directly from a manufacturer or distributor, or obtaining it through a third-party chemical supplier. It is important to follow proper handling and storage procedures for Triethyl citrate to prevent degradation and ensure its effectiveness in various applications. Transporting Triethyl citrate may involve compliance with specific regulations and safety guidelines to prevent accidents and ensure proper handling during transit.
⚠️ Safety Considerations
Safety considerations for Triethyl citrate include its potential for eye and skin irritation upon contact. It should be handled with caution to prevent any direct exposure to the substance. Proper ventilation should be ensured when working with Triethyl citrate to prevent inhalation of vapors. Additionally, suitable personal protective equipment such as gloves, goggles, and lab coats should be worn to minimize the risk of accidental exposure.
Hazard statements for Triethyl citrate include its potential for causing skin and eye irritation. It may also cause respiratory irritation if inhaled. Furthermore, prolonged or repeated exposure may result in dermatitis. It is important to handle Triethyl citrate with care and take necessary precautions to avoid any adverse health effects.
Precautionary statements for Triethyl citrate include avoiding direct contact with the eyes, skin, and clothing. In case of contact, rinse with plenty of water and seek medical advice if irritation persists. When working with Triethyl citrate, it is important to use appropriate protective equipment such as gloves and goggles. Store the substance in a cool, well-ventilated area away from incompatible materials.
