有机物的分离、提纯及检验是融有机基础知识和实验技能于一体的一类题型,在复习中应注意基础知识是否落实到位,实验技能、技巧是否准确规范,逻辑思维是否严密流畅等等.一、有机物的检验与鉴别1.检验与鉴别的常用方法(1)根据溶解性的情况,大部分有机物都不溶于水,如酯类物质、苯、CCl4等,而少数物质却易溶于水(或任意比互溶)如:乙醇、甘油、乙醛,因此用水即能 The separation, purification and inspection of organic matter is a type of problem that integrates organic basic knowledge and experimental skills. In reviewing, we should pay attention to whether the basic knowledge is in place, whether the experimental skills and techniques are accurate and standardized, and whether logical thinking is tight and smooth. I. Inspection and identification of organic matter 1. Common methods for inspection and identification (1) According to the solubility, most of organic matter is insoluble in water, such as esters, benzene, and CCl4, while a few substances are soluble in water. (or any ratio of mutual solubility) such as: ethanol, glycerol, acetaldehyde, so water can be
