2.The removal of astringency were inhibited by pyrazole and hot-water (70℃, 30min), but not inhibited by cycloheximide and cordycepin.

在此状态下环己骈胺及蛹虫草菌素对脱涩并无抑制作用，但吡及热水处理则有抑制效果。

3.Pyrazole has been prepared through the dehydrogenation of 2 pyrazoline in which catalytic amonts of sodium iodide acts as dehydrogenation agent in sulfuric acid.

在硫酸中用碘化钠(催化量)作脱氢试剂使2吡啉脱氢制备吡。

4.Among of them, indoles and pyrazoles are of great importance and they are also hotspots that organic chemists are researching.

吲哚和吡是含氮有机杂环化物的两大类型，它们也是有机化学家研究的热点问题。

5.The pyrazoles ramification containing dithioether is synthesized by one-step method and characterized by H-NMR, IR and UV-Vis spectra.

并采用氢核磁共振，红外光谱和紫外吸收光谱等手段进行了表征。

6.A planar tetradentate dinuclear ligand, 3, 5-bis(2-pyridyl) pyrazole, was synthesized by a three-step reaction of esterification, condensation and addition.

以2-吡啶甲酸为原料，经酯化、缩、了平面四齿双核配体3，5-二（2-吡啶基）吡。
