A novel aromatic diamine monomer, 4-(4-(1-pyrrolidinyl)phenyl)-2,6-bis(4-(4aminophenoxy)phenyl)pyridine (PPAPP) containing pyridine rings, pyrrolidine groups, and ether linkages, was successfully synthesized using 4-hydroxyacetophenone and 1-chloro-4-nitrobenzene as starting materials by three-step reactions, and then used to synthesize a series of polyimides by polycondensation with various ar...
1-Chloro-3-nitrobenzene (3-CNB) is an aromatic halo-amine compound used as chemical intermediate for the production of several fine chemicals like pharmaceuticals, dyes, agricultural chemicals, etc. The stable isotope ratio analysis has drawn attention in numerous fields such as agricultural, food authenticity, biochemistry, etc. The objective of the current research was to investigate the impa...
in this study adsorption of 1-chloro-4-nitrobenzene (cnb) from aqueous solutions onto multi-walled carbon nanotubes (mwcnts) was surveyed. the effect of some key parameters such as ph (2-10), carbon nanotubes dosage (0.02-0.1 mg/250ml), cnb concentration (2- 16 mg/l), and temperature (20,30,40,50°c) were investigated. the results showed that, the variation of initial ph and cnb concentration ex...
