Di-sec-butyl ether

The only important by-product is di-sec-butyl ether, which may be recovered. 

One of the most critical parameters in the SBA production is the process temperature. Since the catalyst performance is slowly degrading because of SO3H loss, to maintain constant productivity, the temperature of the catalyst bed needs to be gradually raised to approximately 170 °C. This leads to further loss of acid functionality and an increase in the level of di-,sec-butyl ether.

Ethers. Low yields of several compounds were obtained when ethvl ether was heated at 130-140 under ethylene pressure in the presence of di-t-butyl peroxide and hydrochloric acid (Expt. 26, Table V). Ethylation took place in the normal fashion to yield ethyl sec-butyl ether by monoethylation together with at least three ethers having eight carbon atoms di-sec-butyl ether, (ethylation at both secondary carbon atoms of the ethyl ether), ethyl 1-methyl-l-ethylpropyl ether (ethylation at the tertiary carbon atom of the primary product) and ethyl-1-methylpentyl ether formed by telomerization of the primary radical with two molecules of ethylene). Some Cio ethers were also formed.
