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.
