PROCEDURE FOR THE PREPARATION OF ALKYL-TERT BUTYLETERS. |
| abstract |
In the processes for the synthesis of alkyl-tert-butyl ethers by reacting the isobutene contained in a C4 charge with a high butadiene content with aliphatic alcohols, to the purpose of preventing polymerization phenomena in the step of separation of alkyl-tert-butyl ether product from the other unreacted components, the initial C4 charge and/or the aliphatic alcohol are submitted to an oxygen removal step, to the purpose of removing all of dissolved free oxygen, down to a maximum residual content of 1-2 ppm. |
