一、Core Product Information
- Name: 2,2 ‘- Azobis [2- (2-imidazolin-2-yl) propane] Dihydrochloride
- CAS number: [27776-21-2] – Unique chemical identifier to ensure product traceability and purity
- Molecular formula and molecular weight: C12H23ClN6, MW: 286.81
- Common abbreviations: AIBA series derivatives, or water-soluble azo initiators
- Structural formula：
二、 Key features and advantages
This product belongs to azo initiators, which introduce hydrophilic imidazoline groups into their molecular structure and form salts, thereby endowing them with unique properties:
- Excellent water solubility: The dihydrochloride form makes it highly soluble in water and various polar solvents at room temperature, making it particularly suitable for aqueous reaction systems without the need for additional organic co solvents, resulting in a purer and more environmentally friendly system.
- High efficiency decomposition at medium and low temperatures: Its decomposition temperature (usually in the range of 40-60 ℃, depending on pH and system) is significantly lower than many traditional oil soluble azo initiators (such as AIBN). This enables it to rapidly generate free radicals under mild conditions, effectively initiate polymerization, reduce energy consumption, and is suitable for heat sensitive monomers.
- High initiation efficiency: The decomposition products are nitrogen and free radical fragments, where nitrogen release is pollution-free, while free radical initiation efficiency is high, which helps to obtain polymers with narrower molecular weight distribution and more controllable structure.
- Excellent applicability: widely used in monomers such as acrylamide, acrylic acid, N-vinyl pyrrolidone (NVP), methyl methacrylate, etc.:
Aqueous solution polymerization
Lotion polymerization
Inverse lotion polymerization
Functional Polymer Synthesis
三、 Main application areas
