New software for creating green solvents

Eleanor Merritt writes on a HOT Green Chemistry article for Chemistry World

Scientists in France have developed a computer-assisted organic synthesis program to design sustainable solvents from bio-based building blocks.

The GRASS software has a green chemistry-focussed approach to solvent design

Finding clean, sustainable alternatives to petroleum-derived solvents and chemicals is a matter of increasing urgency in the chemical industry worldwide. Concerns over health, safety, economic and legal issues, together with a need to minimise the environmental impact of industrial processes have led to increased interest in developing new solvents, particularly those derived from biomass. While a number of computer-aided organic synthesis tools have been developed to aid molecular design and synthetic planning over the past few decades, they have not found widespread application in commodity chemical synthesis.

Traditional synthesis planning combines specialist chemical knowledge and careful literature analysis. GRASS, short for GeneratoR of Agro-based Sustainable Solvents, the software developed by Jean-Marie Aubry at the University of Lille Nord de France and co-workers, challenges this tradition and provides a wholly green chemistry-focussed approach to solvent design on an industrial scale.
