Valorisation of lignin by depolymerisation and fractionation using supercritical fluids and conventional solvents (2017)
Journal Article
Perez, E., Tuck, C. O., & Poliakoff, M. (in press). Valorisation of lignin by depolymerisation and fractionation using supercritical fluids and conventional solvents. Journal of Supercritical Fluids, https://doi.org/10.1016/j.supflu.2017.07.033

A procedure for Lignosulphonate valorisation is investigated. An attempt has been made to obtain diverse value-added products maximizing the atom economy. This procedure is carried in sequential steps starting with an oxidative depolymerization in su...

Continuous niobium phosphate catalysed Skraup reaction for quinoline synthesis from solketal (2017)
Journal Article
Jin, J., Guidi, S., Amara, Z., Selva, M., George, M. W., & Poliakoff, M. (2017). Continuous niobium phosphate catalysed Skraup reaction for quinoline synthesis from solketal. Green Chemistry, 19(10), 2439-2447. https://doi.org/10.1039/C6GC03140D

Solketal is derived from the reaction of acetone with glycerol, a by-product product of the biodiesel industry. We report here the continuous reaction of solketal with anilines over a solid acid niobium phosphate (NbP), for the continuous generation...

Continuous N-alkylation reactions of amino alcohols using γ-Al2O3 and supercritical CO2: unexpected formation of cyclic ureas and urethanes by reaction with CO2 (2017)
Journal Article
Streng, E. S., Lee, D. S., George, M. W., & Poliakoff, M. (2017). Continuous N-alkylation reactions of amino alcohols using γ-Al2O3 and supercritical CO2: unexpected formation of cyclic ureas and urethanes by reaction with CO2. Beilstein Journal of Organic Chemistry, 13, https://doi.org/10.3762/bjoc.13.36

The use of γ-Al2O3 as a heterogeneous catalyst in scCO2, has be successfully applied to the amination of alcohols for the synthesis of N-alkylated heterocycles. The optimal reaction conditions (temperature and substrate flow rate) were determined usi...
