冰醋酸
乙酸,也叫醋酸、冰醋酸,化学式CH3COOH,是一种有机一元酸,为食醋内酸味及刺激性气味的来源。纯的无水乙酸(冰醋酸)是无色的吸湿性固体,凝固点为16.7℃(62℉),凝固后为无色晶体。尽管根据乙酸在水溶液中的解离能力它是一种弱酸,但是乙酸是具有腐蚀性的,其蒸汽对眼和鼻有刺激性作用。
冰醋酸 即 乙酸 。
 
相对密度(水为1):1.050
  凝固点(℃):16.7
沸点(℃):118.3
 
粘度(mPa.s):1.22(20℃)
 
 
  20℃时蒸气压(KPa):1.5
 
 
  外观及气味:无色液体,有刺鼻的醋味。
 
 
  溶解性:能溶于水、乙醇、乙醚、四氯化碳及甘油等有机溶剂。
 
 
  相容性:材料:稀释后对金属有强烈腐蚀性,316#和318#不锈钢及铝可作良好的结构材料。
 
 
  国家产品标准号:GB/T 676-2007
 
 
  乙酸在常温下是一种有强烈刺激性酸味的无色液体。乙酸的熔点为16.6℃(289.6K)。沸点117.9℃ (391.2 K)。相对密度1.05,闪点39℃,爆炸极限4%~17%(体积)。纯的乙酸在低于熔点时会冻结成冰状晶体,所以无水乙酸又称为冰醋酸。乙酸易溶于水和乙醇,其水溶液呈弱酸性。乙酸盐也易溶于水。
