Our team conducted reduction of 4-NP to 4-AP, which synthesize paracetamol with 4-AP as a precursor, in NaBH4-reducing agent and catalysis by Cu-CuO doping on carbon derived from nata de coco. We have heard information that we con use extraction and recrystalization to isolated 4-AP, how ever we still wonder which types of green-solution, which isn't harmful to environment, that use to dissolve in 4-AP (cause it hardly dispered in water and some types of substances similar it). Can someone help us with it.

Thank a lots everyone!!
