Unlike cellulose, a plant cell wall component with a repeating polymer structure, lignin is a complex and random polymer. The chemical units are linked by different connectivities, so one single process cannot attack all of these bonds. Previously, monomers and dimers were used to model chemical linkages of lignin, but were too simple for the study of lignin itself. More complex trimers, tetramers and hexamers have been synthesised, but with inefficient, low-yielding methods.  read all at   http://www.rsc.org/chemistryworld/2013/10/model-lignin-oligomers-biofuel

New software for creating green solvents

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

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

 

Finding clean, sustainable alternatives to petroleum-derived solvents and chemicals is a matter of increasing urgency in the chemical industry worldwide.
