Urinary clearance of NMP (0.03 to 0.07 mL/min) indicates intensive tubular reabsorption. 5-HNMP was the main urinary metabolite and accounted for 42 to 55% of the administered doses. Its maximal urinary excretion occurred between 4 and 6 hr after administration of the three lowest doses and between 8 and 24 hr for the two highest doses.

2017年12月1日 · N-methyl-2-pyrrolidone (NMP) has been shown to be the most effective solvent for liquid phase exfoliation and dispersion of a range of 2D materials...

2023年1月5日 · An NMR spectrometer (Brucker Avance II DMX 400 MHz) was operated in a deuterium interlocked mode to record 1H NMR spectra at 400 MHz at 25℃ for the NMP/(d)H 2 O and NMP/(d)CH 3 OH systems. Computational chemistry is helpful to better understand the photophysical and photochemical properties of molecules.

The results of 1 H NMR researches concerning the interaction between fullerene C60 and N-methyl-2-pyrrolidone (NMP) molecules in an as-prepared solution are reported.

2007年5月27日 · The paper reports the results of FT IR, NIR and 1 H NMR study of N -methylpropionamide (NMP) in carbon tetrachloride solution and in presence of cyclic ethers as the O-electron donors: tetrahydrofuran (THF) and tetrahydropyran (THP). The spectroscopic characteristics for N–H⋯O hydrogen bonded complexes are given.

2014年8月14日 · Our calorimetric study evidenced the presence of strong interactions between NMP and water and revealed that, under comparable conditions, the solvation of NMP by water results in an interaction stronger than the solvation of water by NMP. Overall, the changes of 1 H and 13 C chemical shifts and 2D ROESY spectra upon dilution suggested a ...

摘要： 以四氯化碳作为惰性参考溶剂, 研究了N-甲基-2-吡咯烷酮 (NMP)、环丁砜、N,N-二甲基甲酰胺 (DMF)、N,N-二甲基乙酰胺 (DMA)和γ-丁内酯 (γ-BL)等五种萃取剂在几种芳烃溶剂中的~1H NMR谱。观察到萃取剂分子的化学位移在芳烃溶剂中均大幅度移向高场, 且NMP、γ-BL的共振谱线在芳烃中发生分裂或重叠。在不同的芳烃溶剂中,...

2013年9月9日 · Since the understanding of the NMP/W system properties at the molecular level should largely facilitate the prediction of selectivity of this system, we have performed a NMR spectroscopy...
