TRIETHANOLAMINE TRIACETATE - Introduction
TRIETHANOLAMINE TRIACETATE, also known as TETA, is an organic compound with the chemical formula C12H27NO9. It is a colorless to yellow liquid with a strong ammonia odor. The following is a description of its nature, use, preparation and safety information:
Nature:
1. TETA is a strong base, which can be neutralized with acid to form salt.
2. It is a polar solvent and can be well dissolved in water.
3. The aqueous solution of TETA is alkaline.
Use:
1. TETA is widely used as a metal chelating agent and can form a stable complex with metal ions for metal cleaning, metal rust prevention, metal surface treatment and other industries.
2. It can also be used in the production of polyurethane and epoxy resins, used as a component of adhesives, coatings and preservatives.
3. TETA can also be used in water treatment as a buffer and chelating agent to remove heavy metal ions in water.
Preparation Method:
The preparation of TRIETHANOLAMINE TRIACETATE can be obtained by reacting triethanolamine with acetic acid. The specific steps are that triethanolamine and acetic acid are added into the reaction vessel in a certain proportion, heated and stirred for reaction. After completion of the reaction, the final product was purified by distillation.
Safety Information:
1. TETA is an irritating and corrosive substance that may cause irritation and burns when in contact with skin and eyes. Appropriate protective equipment should be worn during operation to avoid direct contact with skin and eyes.
2. It should be stored in a dry, well-ventilated place, away from fire and oxidant.
3. During transportation and storage, it is necessary to prevent contact with acids, oxidants and other substances to avoid dangerous reactions.
4. in the use of the process should pay attention to avoid inhalation of gas, steam or mist, and keep the operating area well ventilated. If exposed, rinse immediately with clean water and seek medical attention.
