说明

General description

4-Hydroxy-TEMPO benzoate is a 4-substituted 2,2,6,6-tetramethylpiperidyl-1-oxy (TEMPO) derivative.

Application

次氯酸盐/亚溴酸盐-硝基氧氧化体系的循环催化剂，该体系用于醇转化生成醛、酮和羧酸。它避开了催化或化学计量重金属氧化剂的使用。

4-Hydroxy-TEMPO benzoate was employed as spin probe to investigate the mechanism of synthesis of SBA-15 and to evaluate its surface properties and pore structure by electron paramagnetic resonance spectroscopy (EPR). It was also used for the functionalization of various polydienes (polybutadiene and polyisoprene). Functionalized polydienes were analyzed by gel permeation chromatography.

TEMPO催化氧化

TEMPO（2,2,6,6-四甲基哌啶氧基或2,2,6,6-四甲基哌啶1-氧基）及其衍生物在有机氧化反应催化剂中可以作为稳定的硝酰基使用。TEMPO由Lebedev和Kazarnovskii于1960年发现，其具有的稳定自由基性质得益于其庞大的取代基团阻碍了自由基与其他分子之间发生反应。

Oxygen is essential in physiology and pathophysiology. Electron paramagnetic resonance (EPR) oximetry, using oxygen sensitive paramagnetic materials, could be attractive for measuring oxygen in tissues. The aim of the present study was to assess the properties of lipid nanocapsules (LNCs)
