Ethyl alcohol is more soluble than dimethyl ether due to the presence of intermolecular hydrogen bonding. The combination of the hydrogen-bond-accepting oxygen and its small size, and the fact that it is slightly polar (1.15 D versus 1.85D for water) all provide considerable justification why diethyl ether would be expected to be slightly soluble in water. Examples of Solubility Parameters taken from "Solubility of Polymers", Encyclopedia of Polymer Technology, 2nd. Like dimethyl ether, it is fairly water soluble. For example, dimethyl ether and ethanol (both having the molecular formula C 2 H 6 O) are completely soluble in water, whereas diethyl ether and 1-butanol (both C 4 H 10 O) are barely soluble in water (8 g/100 mL of water). 3 Chemical and Physical Properties Expand this section. Viscosity. A degree of substitution of 1.6–1.8 is usual since the resultant ether is soluble in cold water but not in hot.
