Overview
Acetamide, also known as ethanamide, is an organic compound with the formula CH3CONH2. It is the simplest amide derived from acetic acid and is widely used in industrial and laboratory settings. Acetamide is a colorless crystalline solid with a mild odor, and it is hygroscopic, meaning it readily absorbs moisture from the air. Acetamide is produced through the dehydration of ammonium acetate or by the reaction of acetic anhydride with ammonia. It is a versatile compound with applications in various industries, including pharmaceuticals, plastics, and textiles.
Physical and Chemical Properties
Acetamide is a white crystalline solid with a melting point of 79-81 °C and a boiling point of 221 °C. It has a density of 1.159 g/cm³ and is soluble in water, alcohol, and chloroform. The compound is hygroscopic, meaning it absorbs moisture from the air, which can affect its handling and storage. Acetamide forms stable complexes with metal ions, making it useful in various chemical reactions. It has a mild odor and is relatively stable under normal conditions, but it can decompose when heated to high temperatures, releasing toxic fumes of nitrogen oxides.
Main Applications
Acetamide is used as a solvent and plasticizer in the production of plastics, resins, and textiles. It is also employed in the synthesis of pharmaceuticals, including antibiotics and other medicinal compounds. In the laboratory, acetamide serves as a reagent in organic synthesis and as a stabilizer for peroxides. Additionally, acetamide is used in the production of methylamine and other organic compounds. Its ability to form complexes with metal ions makes it valuable in analytical chemistry and industrial processes.
Safety and Storage
Acetamide should be stored in a cool, dry, well-ventilated area away from heat sources and open flames. It is hygroscopic, so containers should be tightly sealed to prevent moisture absorption. Proper handling procedures, including the use of personal protective equipment (PPE), should be followed to avoid skin and eye contact. In case of exposure, rinse affected areas with plenty of water and seek medical attention if irritation persists. Acetamide is not highly toxic, but prolonged exposure or inhalation of dust should be avoided. Always refer to the material safety data sheet (MSDS) for detailed safety information.
B2B Procurement Guide
When procuring acetamide, buyers should verify the purity and quality of the product, typically specified by the supplier. Common purity grades include industrial grade (≥98%) and laboratory grade (≥99%). It is essential to request a certificate of analysis (CoA) and material safety data sheet (MSDS) from the supplier. Prices for acetamide vary depending on purity and quantity, with bulk purchases often available at discounted rates. Buyers should also consider packaging options, such as 25 kg bags or drums, and ensure compliance with local regulations for transportation and storage.
