冰醋酸 又 称:冰乙酸,醋酸 学 名:乙酸 英文名称:Glocial Acetic Acid,Acetic Acid Solution 分子式:CH3 COOH 特 性:为无色透明液体,当温度在其熔点(16.7℃)以下时,凝固成冰状结晶体,故得名“冰醋酸”。具有刺激性的酸臭味,是一种最普通的有机酸,溶于水、乙醇、乙醚、四氯化碳及甘油等有机溶剂中,也能溶解磷、硫、氢卤酸等,不溶于二硫化碳。与醇起酯化反应生成酯,与金属及其氧化物作用生成盐。结晶后体积膨胀,天气炎热时常因瓶内蒸气压升高而顶开瓶塞,使酸气四溢,造
Glacial acetic acid, also known as: glacial acetic acid, acetic acid Scientific name: Acetic acid English name: Glocial Acetic Acid, Acetic Acid Solution Molecular formula: CH3 COOH Properties: colorless transparent liquid, when the temperature below its melting point (16.7 ℃) Crystal, so named “glacial acetic acid.” Irritant sour smell is one of the most common organic acids, dissolved in water, ethanol, ethyl ether, carbon tetrachloride and glycerol and other organic solvents, but also can dissolve phosphorus, sulfur, hydrohalic acid and so on, insoluble in Carbon disulfide. Esterification with alcohol esterification, with the role of metal and its oxide salt. After the crystal volume expansion, the hot weather is often due to the bottle of steam pressure and open the bottle stopper, sour gas overflow, made
