Abstract
Solubility and tie line data-have been measured for bis(2-methylpropyl ) ether + phosphoric acid + water at 25, 51, and 60 degrees C. This sy stem presents a-three-phase region at temperatures greater than 49.5 d egrees C. The extension of the two-phase region, as well as that of th e three-phase region, increases with temperature (i.e., decreasing sol ubility). The behavior of this system has been compared to those of di propyl ethers (bis(1-methylethyl) ether, dipropyl ether, and 1-methyle thyl propyl ether), showing the influence of chain branching on the ap pearance of the three-phase region.
