Physical and Chemical Properties | Ethyl lithium, chemical formula C2H5Li. It is a colorless flake crystal. Melting point 95 ℃ (in nitrogen atmosphere). At sublimation, the vapor consists of hexamer and tetramer molecules. It is easily soluble in pentane, hexane or heptane, soluble in benzene, and is hexamer in solution. Decompose in water. When heated, it is decomposed into ethylene, lithium hydride and a small amount of butane and butene. |
Risk Codes | R45 - May cause cancer R46 - May cause heritable genetic damage R11 - Highly Flammable R36/38 - Irritating to eyes and skin. R48/23/24/25 - R65 - Harmful: May cause lung damage if swallowed R51/53 - Toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. |
Safety Description | S53 - Avoid exposure - obtain special instructions before use. S36/37 - Wear suitable protective clothing and gloves. S45 - In case of accident or if you feel unwell, seek medical advice immediately (show the label whenever possible.) S62 - If swallowed, do not induce vomitting; seek medical advice immediately and show this container or label. S61 - Avoid release to the environment. Refer to special instructions / safety data sheets. S26 - In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. S16 - Keep away from sources of ignition. |

Preparation | Ethyl lithium can be prepared by reacting bromoethane and metal lithium in pentane. |
Precautions | The dry solid of ethyl lithium is easy to catch fire when exposed to the air. The solution is flammable and corrosive, and will react violently when exposed to water. After a week of storage at low temperature, nearly half of the reagent will be converted into ethane, ethylene and acetaldehyde. |
