ETBE and TAEE can be satisfactorily produced in the same reaction unit.
Olefins selectivity toward ethers is remarkably high (> 90%).
The initial alcohol concentration is a controlling variable for side reactions.
Empirical expressions able to predict experimental ether yield are provided.
Maximum ether yield has been obtained at 323 K, RA/O = 0.9 and RC4/C5 = 0.5.
