- Decolorization of Azo Dyes Using Quinone Reductase and Quinoid Compounds
醌还原酶-醌类化合物对偶氮染料脱色的作用 - A condensation to quinoid systems occurs.
发生了醌型体系的缩合反应。 - When the PH of the solution was lower than 4, the structure of DAB changes from an azo type to a quinoid type. This change was studied by SERS and the reversibility of transformation was found.
当溶液PH值小于4时，由于质子化，DAB分子将从偶氮型结构转变为醌型结构，本章利用SERS技术，研究了其结构的这种变化，并且发现这种结构的变化是可以逆转的。 - The results showed that during the chemical pretreatment the guaiacyl unit was more readily to be sulfonated and dissolved, and there were new conjugated carbonyl and quinoid structure formed.
结果表明，预处理过程中愈创木基易于磺化和溶出，木素中有新的共轭羰基和醌型结构产生。 - Spectrophotometric Determination of NO_Based on the Synthetic Reaction of the Quinoid Dye
利用醌式染料的合成反应光度法测定水中亚硝酸根 - During the bleaching process, there were no significant change of lignin structure unit. The conjugated carbonyl and quinoid structure had a close relationship with the pulp brightness and bleachability.
漂白过程中木素结构单元比例变化不大，木素中的碳基及醌型结构与纸浆白度有密切的关系。 - A heat labile, dialysable unknown factor in plasma was found to be capable of catalyzing the oxidation of DMAP to a red quinoid product. The oxidized DMAP may interfere with the determination of MetHb, when the DMAP concentration is high.
实验发现，血浆中有一热不稳定，可经透析除掉的小分子物质能催化DMAP氧化成红色的醌，干扰MetHb测定。
