The selective hydrogenation of furfural into cyclopentanone is an attractive transformation to advance in the sustainable synthesis of important chemicals from biomass.

A straightforward, one-pot approach for novel ion imprinted mesoporous silica materials (IMS) has been developed by co-condensation.

The undiluted ionic liquid trihexyl(tetradecyl)phosphonium nitrate was used for cobalt–samarium and nickel–lanthanum separations by solvent extraction.

This manuscript describes the development of an efficient process for the recovery of rare earth elements from materials mixtures such as in motors with a recovery rate of >80%. Selective dissolution enables efficient separation of steel and copper and selective precipitation of RE salts is the key for obtaining pure RE products.
