In soldering, the flux removes oxide films, promotes wetting, and prevents reoxidation of the surfaces during heating. 在焊接时，熔剂用来除掉氧化皮，提高浸润性，防止加热时表面再氧化。
The reduction of insoluble quinones to soluble hydroquinones and reoxidation in air to the quinone structure is the principle involved in dyeing cloth with"vat" dyes. 瓮染燃料对布料着色的原理在于不溶性醌类的还原和可溶性氢醌于空气中被再氧化至醌类结构。
