Triethylamine (TEA) is a versatile tertiary amine used widely as a base, catalyst, and solvent. It is a colorless liquid with a strong, fish-like ammonia odor, providing exceptional reactivity in various organic synthesis pathways.
In the coatings industry, TEA is an essential Technical Grade neutralizing agent for water-borne resins. It ensures the stability and solubility of polyester and polyurethane dispersions, facilitating a high-quality finish and faster curing.
As a catalyst, it is indispensable in the production of pharmaceutical intermediates, agrochemicals, and casting resins. Its ability to act as an acid acceptor makes it a critical component in esterification and alkylation reactions.
SoleChem, an ISO 9001:2015 certified chemical supplier based in Türkiye, delivers Triethylamine (CAS 121-44-8) to customers in more than 40 countries.
