benzoquinone

A theoretical study on the mechanism of the Diels-Alder reactions of masked o-benzoquinone radical cation with furan

呋喃与掩蔽的邻位苯醌阳离子基的Diels-Alder反应的理论研究

Phenol, benzoquinone, nitrosobenzene and azobenzene were identified as the main intermediates for gaseous aniline degradation.

纳米TiO2光催化降解气态苯胺的中间产物主要有苯酚、苯醌、亚硝基苯和偶氮苯等。

Fe ( III) EDTA was found to be efficient in PdCl_2/ Fe ( III) EDTA/ 1,4-benzoquinone ( BQ)/ tetrabutylammonium bromide ( TBAB) catalyst system.

发现了Fe（III）EDTA在PdCl2/Fe（III）EDTA/1,4-苯醌/四丁基溴化铵催化体系中具有很好的助催化效果。

we also investigate the influence of several reaction conditions such as rare earth type, ionic liquid volume, reaction time, benzoquinone content and system pressure, on the catalytic activity.

考察了稀土种类、离子液体量、反应时间、苯醌用量、体系压力等因素对催化活性的影响。

The visible absorption spectra of p-benzoquinone ( PBQ) in CS_2 were measured, and a weak absorption band around 507 nm attributed to n-π~ singlet-triplet transition was demonstrated.

测量了对苯醌（p-benzoquinone，PBQ）在CS2中的可见吸收光谱，论证了该实验中发现的507nm带来源于PBQ的n-π单-三态跃迁。

Benzoquinone, maleic acid, are also identified as intermediates by HPLC.

用HPLC还检测到苯醌和顺丁烯二酸。
