Pharmacopoeias.

In Eur., Jpn, and US.

Ph. Eur. 6.2

(Ether). A colourless, clear, volatile, highly flammable liquid. It may contain a suitable non-volatile antoxidant at a suitable concentration. Relative density 0.714 to 0.716. Distillation range 34° to 35°. Soluble in water; miscible with alcohol, with dichloromethane, and with fatty oils. Store at 8° to 15° in airtight containers. Protect from light.

USP 31

(Ether). A colourless, mobile, volatile, flammable liquid, having a characteristic sweet, pungent odour. It is slowly oxidised by the action of air and light, with the formation of peroxides. B.p. about 35°. Sp. gr. 0.713 to 0.716. Soluble 1 in 12 of water; miscible with alcohol, with chloroform, with dichloromethane, with petroleum spirit, with benzene, and with fixed and volatile oils; soluble in hydrochloric acid. Store in partly filled airtight containers at a temperature not exceeding 30° and remote from fire. Protect from light.

Stability.

Though ether is one of the lightest of liquids, its vapour is very heavy, being 2 ⁄ times heavier than air. Ether is very volatile and flammable and mixtures of its vapour with oxygen, nitrous oxide, or air at certain concentrations are explosive. It should not be used in the presence of an open flame or any electrical apparatus liable to produce a spark; precautions should be taken against the production of static electrical discharge. Explosive peroxides are generated by the atmospheric oxidation of solvent ether and it is dangerous to distil a sample which contains peroxides.

💊 Adverse Effects

As for Anaesthetic Ether. Ingestion of 30 to 60 mL may be fatal.

💊 Uses

Solvent ether is widely used as a pharmaceutical and industrial solvent, and is used as an extraction solvent in food processing.
