NEW AND UNUSUAL SOLVENT POTENTIAL What makes the potential of acetonitrile unusual? Unique properties. They account for superior perform ance over a wide range of applications. Check these examples: Greater selectivity. As a recrystallization solvent, aceto is particularly practical in the separation of fatty acids. In liquid-liquid separations, several companies are evaluating aceto as a preferred solvent in place of phenol and furfural. One company, previously using acetone in an extractive distillation process, changed to aceto and process efficiency shot up 58%! High solubility parameter and low hydrogen bonding
make aceto well suited as a solvent for polymers and copolymers. With a parameter of 11.9, aceto shows un usual promise. And, with Sohio providing a volume source, acetoni trile now takes on a new commercial attractiveness. Whatever your interest, now is a good time to explore what Sohio acetonitrile has to offer.
