"On Diethyl Ether and Ethyl Acetate"

Now there are diethyl ether and ethyl acetate, both of which are organic agents. They have their own uses in chemical industry, and the differences are also obvious.

Diethyl ether is relatively sparse in nature. The boiling point is quite low, only about 34.6 ° C, and it is very volatile. At room temperature, it is often in a state of gas. Its taste is specific, people smell it, and feel it is cool. And flammable. If it encounters an open flame or a hot topic, it is dangerous to explode. Therefore, when storing, transporting and using it, you must beware of fire sources. Its solubility is unique, it can dissolve many organic substances, such as oils, resins, etc. However, its solubility in water is very small, and its affinity with water is weak due to its molecular structure.

As for ethyl acetate, the boiling point is about 77.1 ° C, which is higher than that of diethyl ether, and its volatilization is slightly slower. Its taste is fragrant, and it is often smelled like a fragrance, which makes people feel fresh. Although its flammability exists, it is slightly less dangerous than diethyl ether. In terms of solubility, it can not only dissolve a variety of organic substances, such as ethanol, acetone, etc., but also has a certain solubility in water. Because there are both hydrophobic hydrocarbon groups and hydrophilic ester groups in the molecule, it can be soluble with water to a certain extent.

The two are used differently in the chemical industry. Diethyl ether is often used as a solvent to extract active ingredients from plants. Because it is volatile, it is easy to separate after extraction. And ethyl acetate is mostly used for fragrance preparation, because of its fragrant taste, it can increase the fragrance of flavors. In the paint industry, ethyl acetate can form a uniform film of coatings due to its suitable volatilization rate, and is often used as a solvent; although diethyl ether can also be used as a solvent, its application is somewhat limited due to its flammable risk.

From the perspective of this, diethyl ether and ethyl acetate have their own characteristics and can develop their strengths in different fields. People in the chemical industry should know their properties in detail and make good use of them to obtain the full effect and avoid disasters.
