Diethyl ether from ethanol
WebIf the temperature exceeds 140 °C, the ethyl sulfate product tends to react with residual ethanol starting material, producing diethyl ether. If the temperature exceeds 170 °C in a considerable excess of sulfuric acid, the ethyl sulfate breaks down into ethylene and sulfuric acid. Reactions WebJan 23, 2024 · If ethanol is dehydrated to ethene in presence of sulfuric acid at 433 K, but as 410 K, ethoxyethane is the main product.
