Acetamide
Acetamide, an organic compound, possesses a colorless and crystal-clear appearance. Its odor resembles that of mouse secretions, exuding a fascinating allure. It showcases flammability and low toxicity. Moreover, acetamide exhibits solubility in water, ethanol, trichloromethane, pyridine, and glycerol, with a slight solubility in ether. In cases of acute (short-term) exposure, it may lead to mild skin irritation.

Description:
Prepare method:
- Combine glacial acetic acid with ammonia to form ammonium acetate.
- Subject it to pyrolysis and dehydration to obtain acetamide.
- Crystallize and separate the resulting product.
The required amount of raw materials is 1700kg of acetic acid (99%) and 750kg of liquid ammonia (99%) per ton. For laboratory synthesis, adhere to the stepwise procedure outlined below. Begin by placing 3kg of glacial acetic acid in a 5L flask and introducing ammonium carbonate equivalent to 400g of ammonia. Equip the flask with a high-efficiency fractionating column, a condenser, and a receiver. Gradually heat the reaction mixture until it reaches a gentle boil, ensuring the distillation rate remains below 180mg/h. Maintain the temperature increase from the bottom to the top at 110℃. At this stage, you will have a mixture of water and acetic acid, measuring between 1400 and 1500ml. Replace the receiver, increase the heat slowly, and continue distillation at the same rate until the top temperature reaches 140 °C.
The resulting distillate, measuring 500-700ml, mainly consists of acetic acid and should be reserved for subsequent use. Transfer the remaining residue to a flask with a fractionating column and an air condenser for atmospheric distillation. Collect the fractions at pre-210 °C and 210-216 °C, respectively. The latter will be acetamide, weighing 1150-1200g, while the former can also undergo distillation to recover a portion of the product. Combined, Both fractions will weigh 1200-1250g, yielding 87%-90%. Acetamide is often subjected to refining through distillation and solvent recrystallization. Commonly used solvents include acetone, benzene, ethyl acetate, methyl acetate, chloroform, dioxane, or a mixture of benzene and ethyl acetate. For instance, if 1kg of acetamide is prepared using the method above, it can be recrystallized using a mixed solvent composed of 1L of benzene and 300ml of ethyl acetate to yield a colorless, needle-like pure product. The purity of industrially produced acetamide is not less than 98%, and its freezing point is not less than 76 °C.
