Diethylether reaktion
WebDespite the dried glassware and attempt to create a closed system, the reaction was unsuccessful, which lead to data from another group being used to calculate and understand the reaction. The failure for the magnesium to react with the bromobenzene in diethyl ether could be due to exposure to water or oxygen that was failed to be noticed. WebReaction with chlorine produces alpha-chloroethers. Synthesis. Ethers can be prepared by numerous routes. In general alkyl ethers form more readily than aryl ethers, with the later species often requiring metal catalysts. The synthesis of diethyl ether by a reaction between ethanol and sulfuric acid has been known since the 13th century.
