醇的同分异构体,有丙醇的两种同分异构体——正丙醇与异丙醇,两者氧化后的产物前者是醛,后者是酮,基于此可通过银镜反应来鉴别丙醇的两种同分异构体。一、实验用品:试剂:AgNO_3,浓氨水,正丙醇,异丙醇,蒸馏水。仪器:试管3支,铁丝2根,酒精灯(或煤气灯),滴管,烧杯(300ml),洗瓶。二、操作步骤:1.在清洁的试管中放入0.5g AgNO_3,用10ml 蒸馏水溶解,制得约5%的AgNO_3溶液。
Alcohol isomers, there are two kinds of propanol propanol - propanol and isopropanol, both products of the former oxidation is the aldehyde, the latter is a ketone, based on which silver mirror Reaction to identify the two isomers of propanol. First, the experimental supplies: Reagents: AgNO_3, concentrated ammonia, n-propanol, isopropanol, distilled water. Instrument: test tube 3, 2 wire, alcohol lamp (or gas lamp), dropper, beaker (300ml), bottle washing. Second, the steps: 1. In a clean test tube into the 0.5g AgNO_3, dissolved in 10ml of distilled water to prepare about 5% AgNO_3 solution.
