甲酰胺 (Formamide)属于脂肪族酰胺中的单酰胺类 ,是一种无色透明具有弱氨气味的甘油状液体 ,具有吸湿性。甲酰胺介电常数高 ,并且凝固点比一般物质低 ,是一种极好的离子化溶剂 ,具有特殊的溶解能力 ,是许多无机盐 ,高分子聚合物和天然产物的良好溶剂 [1 ]。由于甲酰胺能溶解介 Formamide, a monoamide of aliphatic amides, is a colorless, transparent glycerol-like liquid with a weak ammonia odor and hygroscopicity. Formamide has a high dielectric constant and a lower freezing point than ordinary materials. It is an excellent ionizing solvent with a special ability to dissolve and is a good solvent for many inorganic salts, polymers and natural products [1]. Since formamide can dissolve
