So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Huang, X. H.; Song, J. J.; Li, H.; Gong, M. T.; Zhang, Y. researched the compound: (S)-3-(Piperidin-2-yl)pyridine( cas:494-52-0 ).COA of Formula: C10H14N2.They published the article 《Selective removal of nicotine from the main stream smoke by using a surface-imprinted polymer monolith as adsorbent》 about this compound( cas:494-52-0 ) in Journal of Hazardous Materials. Keywords: nicotine removal stream smoke surface imprinted polymer monolith adsorbent; Adsorption; Molecularly imprinted polymer; Nicotine; Selective removal; Surface-imprinted monolith. We’ll tell you more about this compound (cas:494-52-0).
Using molecularly imprinted polymer as a selective adsorbent for gaseous toxicants is a novel attempt. In present work, a nicotine surface-imprinted monolith (MIM) was used for the selective removal of nicotine from smoke. First, the retention capacity and selectivity for this MIM was tested by using it as the stationary phase in gas chromatog. and chromatog. conditions optimized. Then, the gas phase adsorption isotherms of MIM were constructed and the adsorption thermodn. explored. At last, the applicability for MIM in the removal of nicotine in smoke was explored. Results indicated a stronger retention capacity and a higher selectivity of MIM toward the template vapor, with a capacity factor (87.88) and a selectivity factor (10.15) under the optimized conditions. A higher standard adsorption enthalpy change for this MIM toward the template (|ΔH0a| = 65.53 kJ mol-1) than that for the non-imprinted monolith (NIM) column (|ΔH0a| = 47.46 kJ mol-1) was observed The adsorption isotherm for MIM appears the BET type II shape, while that for the NIM was approx. linear. When this MIM was used as the adsorbent, it exhibited a high performance in the selective removal of nicotine from the main stream smoke, with an adsorption percentage of 99.43%.
