德国化学家多伦(Bernhard Tollen’s)于1882年用硝酸银氨溶液来鉴别醛和酮的试剂,故称多伦试剂。由于反应时试剂与醛作用,使银氨络离子还原成金属银附着在玻璃壁上形成银镜,又称银镜反应,因此是化学法制镜的基础。银镜反应是利用银氨络离子的氧化性,使具有还原性的醛、肼、葡萄糖以及酒石酸等物质,还原生成金属银的反应。实际上是一种氧化还原反应。工业上利用该反应制取保
The German chemist Bernhard Tollen’s used 1850 ammonia nitrate solution to identify aldehydes and ketones, so it is called Doron reagent. As the reaction of reagents and aldehydes, the silver ammonia complex ions reduced to metal silver attached to the glass wall to form a silver mirror, also known as silver mirror reaction, it is the basis of chemical law mirror. Silver mirror reaction is the use of silver ammonia ion oxidation, the reduction of aldehydes, hydrazine, glucose and tartaric acid and other substances, reducing the formation of metal silver reaction. Is actually a redox reaction. Industrial use of the reaction system security
