The di- n- propyl ether (sometimes only dipropyl ether ) is a representative of the class of open-chain ethers . Other representatives of these ethers are, for example, dimethyl ether and diethyl ether . Like other ethers, it is suitable as a solvent.
There are also two isomers , the diisopropyl ether and the isopropyl n -propyl ether .
Extraction and presentation
The conventional production of di- n -propyl ether in the chemical industry takes place through the etherification of n- propanol in the presence of sulfuric acid with elimination of water.
It is an acid-catalyzed condensation reaction between two alcohol molecules .
use
Dipropylether is used in the manufacture of pharmaceutical and pyrotechnic products.
