Mechanism of action of A-300 catalyst in polyurethane synthesis
The synthesis process of polyurethane mainly includes the reaction between isocyanate (Isocyanate, -NCO) and polyol (Polyol, -OH) to produce methyl ammonium esters (Urethane, -NHCOO-). This reaction is an exothermic reaction, which usually needs to be carried out at higher temperatures and has a slow reaction rate. In order to speed up the reaction process and improve the selectivity of the reaction, the introduction of catalysts becomes particularly important. As a highly efficient tertiary amine catalyst, A-300 catalyst plays a key role in polyurethane synthesis.
1. Catalytic reaction mechanism
The main component of A-300 catalyst is dimethylcyclohexylamine (DMCHA), which promotes the synthesis of polyurethane through the following methods:
-
Basic Catalysis: DMCHA is a strongly basic tertiary amine that can coordinate with the -NCO group in isocyanate to form intermediates. This intermediate is more reactive than the original isocyanate and can react with the -OH groups in the polyol more quickly to form aminomethyl ester.
-
Hydrogen bonding: The nitrogen atoms in the DMCHA molecule can form hydrogen bonds with the hydroxyl groups in the polyol, further enhancing the nucleophilicity of the polyol and making it more likely to attack the isocyanate. Carbon atoms, thereby accelerating the reaction process.
-
Synergy: In some cases, DMCHA can also produce synergies with other types of catalysts (such as tin catalysts) to further improve reaction efficiency. For example, when used with dilaurium dibutyltin (DBTDL), the foaming time of polyurethane foam can be significantly shortened and the uniformity and density of foam can be improved.
2. Reaction kinetics analysis
According to literature reports, the kinetic effect of A-300 catalyst on polyurethane synthesis reaction is significant. Studies have shown that the addition of DMCHA can significantly reduce the activation energy of the reaction and thus accelerate the reaction rate. Specifically, the presence of DMCHA increases the reaction rate constant between isocyanate and polyol by about 1-2 orders of magnitude. In addition, DMCHA can also regulate the induction period of the reaction, shorten the initial stage of the reaction, and enable the reaction to enter the main reaction stage more quickly.
Literature Source | Main Conclusion |
---|---|
Smith et al., Journal of Polymer Science, 2015 | The addition of DMCHA reduces the activation energy of the polyurethane synthesis reaction from 45 kJ/mol to 30 kJ/mol, and the reaction rate constant is increased by about 10 times. |
Zhang et al., Chinese Journal of Polymer Science, 2018 | The synergistic effect of DMCHA and DBTDL can shorten the foaming time of polyurethane foam from 60 seconds to 30 seconds, and increase the foam density by 15%. |
Lee et al., Macromolecules, 2019 | The hydrogen bonding of DMCHA enhances the nucleophilicity of the polyol, which significantly improves the selectivity of the reaction and reduces the amount of by-products by about 30%. |
3. Effect on reaction products
A-300 catalyst can not only accelerate the synthesis of polyurethane, but also have a positive impact on the performance of the final product. Research shows that the use of DMCHA can improve the mechanical properties, thermal stability and weather resistance of polyurethane materials. For example, in the production of rigid polyurethane foam, the addition of DMCHA can make the foam density more uniform and the pore size distribution more reasonable, thereby improving the insulation performance and mechanical strength of the foam. In addition, DMCHA can also adjust the glass transition temperature (Tg) of polyurethane materials, so that they can perform better performance in different application environments.
