Solvents are a key priority when greening chemistry because they are used in high volumes and many are volatile organic compounds. Finding safer, more efficient alternatives or removing solvents altogether is one of the best ways to improve a process or product. A liquid that holds another substance in solution, that is, dissolves it. This method, which uses enzymes, achieves higher yields, saves energy and is less expensive.
