性质描述: 无色透明液体。纯乙酸在16℃以下时,能结成冰状固体,故称冰醋酸。与水、乙醇、苯和乙醚混溶,不溶于二硫化碳。当水加到乙酸中,混合后的总体积变小,密度增加。分子比为1:1,进一步稀释,不再发生上述体积的改变。有刺激性气味。

储存注意事项:储存于阴凉、通风的库房。远离火种、热源。冬季应保持库温高于16℃,以防凝固。保持容器密封。应与氧化剂、碱类分开存放,切忌混储。采用防爆型照明、通风设施。禁止使用易产生火花的机械设备和工具。储区应备有泄漏应急处理设备和合适的收容材料。

产品应用:常用作分析试剂、制造乙酸盐,通用溶剂和非水滴定溶剂及色层分析试剂,也用于有机合成:制造醋酸盐、醋酸纤维素、医药、颜料、酯类、塑料、香料等;也是制药、染料、农药及有机合成的重要原料。也可作曲香酒的增香剂。

产品详情

Property description: Colorless transparent liquid. When pure acetic acid is below 16℃, it can form an icy solid, so it is called glacial acetic acid. Miscible with water, ethanol, benzene and diethyl ether, insoluble in carbon disulfide. When water is added to acetic acid, the total volume after mixing decreases and the density increases. The molecular ratio is 1:1, further diluted, and the above volume change does not occur. It has a pungent smell.

Storage precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat. Keep the temperature above 16℃ in winter to prevent solidification. Keep the container airtight. It should be stored separately from oxidizer and alkali, and should not be mixed. Explosion-proof lighting and ventilation facilities are adopted. Do not use mechanical equipment and tools that can easily generate sparks. The storage area should be equipped with leak emergency treatment equipment and suitable holding materials.

Product application: Commonly used as analytical reagent, manufacturing acetate, general solvent and non-aqueous titration solvent and color layer analysis reagent, also used in organic synthesis: manufacturing acetate, cellulose acetate, medicine, pigments, esters, plastics, spices, etc.; It is also an important raw material for pharmaceutical, dye, pesticide and organic synthesis. You can also compose an aroma enhancer for incense wine.
