Synthesis of acetonitrile (cyanomethane, methyl cyanide)

Preparation of acetonitrile

Preparation of acetonitrile (cyanomethane, methyl cyanide)

Preparation of acetonitrile (cyanomethane, methyl cyanide)

15 g of phosphorus pentoxide and 10 g of dry acetamide are mixed together in a flask fitted for a simple distillation. After phosphorus pentoxide and acetamide are shaken well together, the reaction flask is connected with a short condenser, and then heated gently. The dehydration reaction proceeds with much foaming. After the reaction mixture has been heated a few minutes, the acetonitrile begins to distill and collects into the receiver. The distilled crude acetonitrile is treated with half its volume of distilled water, and then solid potassium carbonate is added until the solution is saturated and it is no longer dissolved by the lower layer of liquid. The upper layer which consist of acetonitrile is removed with the separatory funnel and distilled over phosphorus pentoxide which serves as drying agent. The fraction passing at 82°C is collected yielding about 5 g of final product.

Preparation of acetonitrile

Preparation of acetonitrile

68 g of finely powdered potassium cyanide are dissolved in 60 ml of water, in a 500-ml round-bottomed flask, and after cooling 126 g of dimethyl sulphate are added in three equal portions, the whole being shaken vigorously and cooled under water after each addition. During the shaking, the flask is closed by a one-hole cork carrying a glass tube bent three or four times, so as to form a spiral, having its axis horizontal. This prevents spurting out of any liquid. The milky liquid is distilled on a water bath in a fume cupboard at 82° C, a litre flask being used owing to frothing. The residue in the flask is treated on cooling with another 65 g of potassium cyanide, added slowly, in 50% solution as before, and the whole is very cautiously distilled from a water bath. A violent reaction occurs, and then this has slackened, the distillation is continued until the residue in the flask becomes solid and nothing more comes over. The distillate is removed and shaken with half its volume of water; solid potassium car­bonate is added until no more dissolves, the layer of acetonitrile is separated from the aqueous solution and redistilled over phosphorus pentoxide, the fraction 79-83° C being retained. The yield of acetonitrile is 95%. Colourless liquid; ethereal odour ; slightly soluble in water; b.p. 82° C.
