Jeffcat TAP amine catalysts are a class of amine compounds-based catalysts, mainly used in the production of polyurethane (PU) foams. This type of catalyst has the characteristics of high efficiency, environmental protection, and easy to operate, and is particularly suitable for large-scale production. The main component of Jeffcat TAP amine catalyst is triethylenediamine (TEDA), which is a highly efficient tertiary amine catalyst that can significantly accelerate the reaction of isocyanate with polyols, thereby quickly forming polyurethane foam.

3. Chemical properties of Jeffcat TAP amine catalysts

Jeffcat TAPamineThe main component of catalyst-like catalyst is triethylenediamine (TEDA), whose chemical structural formula is C6H12N2. TEDA is a colorless to light yellow liquid with a strong ammonia odor. It is stable at room temperature, but may decompose under high temperature or strong acid and alkali conditions. The boiling point of TEDA is 174°C, the melting point is -45°C, and the density is 0.95 g/cm³.

3.1 Chemical structure

The chemical structure of TEDA contains two nitrogen atoms, connected to three carbon atoms respectively. This structure makes TEDA have high reactivity and can effectively catalyze the reaction of isocyanate with polyols.

3.2 Reaction mechanism

In the production process of polyurethane foam, TEDA as a catalyst mainly accelerates the reaction in the following two ways:

Nucleophilic Catalysis: The nitrogen atoms in TEDA have lone pairs of electrons and can form coordination bonds with carbon atoms in isocyanate, thereby reducing the activation energy of the reaction and accelerating the reaction.
Acidal and alkali catalysis: TEDA can interact with acidic or alkaline substances in the reaction system, adjust the pH value of the reaction environment, thereby further accelerating the reaction.
