Conclusions
-
1.
At ordinary pressures (in a recirculation apparatus) aliphatic ethers undergo disproportionation reactions both with one another and with aliphatic alcohols, alkyl halides, and thioethers to form mixed ethers and the other corresponding products.
-
2.
The ability of the ethers of polyatomic alcohols to undergo disproportionation reactions has been demonstrated in the case of diethylene glycol diethyl ether, and in this case the reaction results in the formation of dioxane and diethyl ether, as well as ethylene glycol diethyl ether. The disproportionation of 1,4-dioxane, 1,3-dioxane, and THF with diethyl ether could not be detected under these conditions. Similarly, ethylene glycol diethyl ether did not undergo any conversion.
