Abstract

Information is given as to the rates of peroxidation of diethyl ether and di‐__iso__propyl ether under normal laboratory conditions of storage, both with and without inhibitors. Di‐__iso__propyl ether peroxidizes in daylight at least twice as rapidly, and in the dark several times as rapidly, as diethyl ether. By storing di‐__iso__propyl ether over 20% caustic soda the ether layer can be maintained almost free from peroxide. Anti‐oxidants effectively protect di‐__iso__propyl ether for limited periods. Diethyl ether can be protected from peroxidation by storage in presence of iron, and can be largely protected merely by storage in the dark.

It is proposed in this paper to review briefly the more recent literature dealing with the peroxidation and avoidance of peroxidation of diethyl and di‐__iso__propyl ethers and to record our own observations under both these heads.

## Abstract For the first time a secondary ion mass spectrum of diethyl ether was obtained at low temperature. The spectrum recording became possible by carefully selecting the range of experimental conditions for the production of a cluster‐type spectrum. This range is specified by the threshold f
