Diethyl ether cannot be prepared by
WebDiethyl ether can be prepared both in laboratories and on an industrial scale by the process called acid ether synthesis. Ethanol is mixed with a strong acid like sulfuric acid (H2SO4). This strong acid dissociates in the aqueous environment producing H3O+(hydronium ions). WebAnd you need to add something like diethyl ether as your solvent. You can't have any water present because water will react with the Grignard reagent. And so this is what you make, over here on the right. You end up with a carbon atom bonded to a metal. Right? So carbon is bonded to magnesium. This is called an organometallic bond.

WebDiethyl ether and chromium trioxide react violently at room temperature. Solid acetyl peroxide in contact with ether or any volatile solvent may explode violently. A 5-gram portion in ether detonated while being carried, [Chem. Eng. News 27:175 (1949)]. Nitrosyl perchlorate ignites and explodes with diethyl ether. WebAnhydrous diethyl ether of the usual commercial grade proved satisfactory. B. Apparatus. Most of the reactions were carried out in three-necked flasks fitted with a mercury-sealed stirrer, a reflux condenser, and a dropping funnel, such as are used for Grignard reactions.
WebWhy is diethyl ether not soluble in water? Both ethers are soluble in water to some extent, as each is a polar molecule. However, diethyl ether is more soluble because its nonpolar chains are smaller than dihexyl ether. The larger nonpolar chains interfere with water's dissolving ability.
