Preparation of diethyl ether

Preparation of diethyl ether

A distilling flask (1/2 liter) is fitted with a thermometer and long condenser. An adapter is fitted to the lower end and passes through the neck of a flask, which is surrounded by ice.

80 ml (150 g) of sulfuric acid and 110 ml (85 g) of ethyl alcohol are cautiously mixed together in the distilling flask, which is then placed upon a sand-bath and attached to the condenser. The mixture is heated to 140° C and alcohol is run in from the tap-funnel at the same speed as the liquid distils (about three drops a second). The temperature must be kept constant at 140-145° C. When about twice the quantity of alcohol contained in the original mixture has been added and converted into ether, the distillation is stopped. The receiver now contains, in addition to ether, alcohol, water and sulfurous acid. The liquid is poured into a large separating funnel and a small quantity (30-40 ml) of dilute sodium hydroxide added and well shaken. After settling, the sodium hydroxide solution is drawn off below, and about the same quantity of a strong solution of sodium chloride added, and the process of shaking and drawing off repeated. The ether, which is now free from sulfurous acid and from most of the alcohol, still contains water. It is therefore poured into a large dry distilling flask and some pieces of solid calcium chloride added. It is allowed to stand loosely stoppered overnight. The next day the distilling flask is attached to a long condenser and heated on the water-bath. The ether, which distils, still contains traces of alcohol and water, which it obstinately retains and from which it can only be freed by a further treatment with metallic sodium. A few very thin slices of sodium are dropped into the receiver and the vessel closed with a cork, through which an open calcium chloride tube is inserted to allow any hydrogen to escape and to prevent the entrance of moisture. When the sodium produces no further action, the ether is decanted from the sodium residues into a distilling flask and distilled on the water-bath. A thermometer is placed in the neck of the flask to indicate the boiling-point, which should be constant at 35° C.

Diethyl ether is colourless, mobile liquid; b.p. 35° C; sp. gr. 0.720 g/ml at 15; burns with a luminous flame; not miscible with water; 9 parts of water dissolve 1 part of ether, and 35 parts of ether dissolve 1 part of water at the ordinary temperature.
