Data Effort Improves Flow Toward 'Greener' Chemistry

Jeopardy answer: Death Valley and "ionic liquids." Correct question: Where does a little bit of water make a whole lot of difference?
Scientists at the National Institute of Standards and Technology (NIST) report* that flow properties for a relatively new class of alternative solvents called ionic liquids are extremely sensitive to tiny amounts of water. For example, for one of these solvents, just a 0.01 percent increase in water dissolved into a sample, caused a 1 percent decrease in flow resistance—a 100-fold effect. The finding should be helpful in the design of new industrial processes such as chemical separations that are both more efficient and more environmentally friendly.
