AI Technical Summary
Existing technologies struggle to efficiently separate carbazole and anthracene from coal tar due to their small polarity difference and eutectic effect, resulting in low yields in crystallization methods. Traditional solvent extraction methods are highly toxic and lack selectivity, while molecular imprinting methods have insufficient material recognition capabilities.
By employing eutectic solvent-guided molecularly imprinted polymers, a DES prepolymer is formed through hydrogen bond acceptors and hydrogen bond donors. This prepolymer is then combined with styrene and 4-vinylpyridine to form a bifunctional polymer network, thereby preparing a polymer with specific pore size and polar recognition capabilities, achieving efficient separation of carbazole and anthracene.
It achieves highly selective and efficient separation of carbazole and anthracene, reduces the toxicity of traditional solvents, improves separation yield and material stability, and is suitable for industrial applications.
