N,N,3-Trimethylaniline, 97%

Product Introduction

N,N,3-Trimethylaniline is an aromatic tertiary amine derivative with strong electron-donating ability.

Its molecular structure contains:

• A dimethylamino group –N(CH₃)₂
• A methyl-substituted aromatic ring

The tertiary amine structure allows efficient electron transfer reactions, making it useful as a reducing component, catalyst precursor, and photopolymerization accelerator.

N,N,3-Trimethylaniline is particularly valuable in light-curing technologies because it can interact with photoinitiators to generate reactive species and improve polymerization efficiency.

Mechanism / Principle

N,N,3-Trimethylaniline mainly functions through electron transfer and radical generation mechanisms.

In photopolymerization systems:

• The aromatic tertiary amine donates electrons to an excited photoinitiator.
• Radical species are generated through charge-transfer reactions.
• The generated radicals initiate polymerization of acrylate and methacrylate monomers.

This mechanism helps improve:

• Polymerization rate
• Light-curing efficiency
• Conversion of reactive monomers
• Curing performance under visible or UV irradiation

It is commonly studied together with photoinitiators such as camphorquinone (CQ), acylphosphine oxide photoinitiators, and other radical-generating systems.
