英文小作文:
Diethyl ether is a colorless liquid that is highly flammable and used in various industries for various purposes. It is commonly used in the production of pharmaceuticals, cosmetics, and other chemical substances. It is also used in the extraction of organic compounds from water using the diethyl ether extraction process, which is a common method used in the environmental industry.
However, diethyl ether should be handled with care as it can cause irritation to the skin and eyes, and it can also be toxic if swallowed or inhaled in large amounts. Therefore, it is important to use it safely and properly to ensure that it does not pose a threat to human health or the environment.
