Levulinic Acid From Corn: Ingredient in Antifreeze

Levulinic acid, like that being extruded below from corn starch, has proven to be an effective ingredient in antifreeze. This chemical could replace the toxic, petroleum-based ingredients now in use. Test results show a 30 percent solution of sodium levulinate had a freezing point of -18 degrees. Researchers expect to enhance levulinic acid yield and to purify the chemical to make it more commercially attractive. If research can make the chemical viable in the marketplace, it can find uses in several industrial and consumer compounds, in addition to antifreeze.
