Herein, we report an approach to produce levoglucosenone (LGO) from cellulose in yields up to 51% under mild reaction conditions (170–230 °C; 5–20 mM H2SO4) using polar, aprotic solvents such as tetrahydrofuran (THF). LGO can be used to make a wide variety of chemicals from biomass...
Recovery of an aprotic polar solvent from a saline aqueous solution of this solvent, by a process which consists in desalinating the said solution by electrodialysis and then distilling the desalinated solution. To avoid the precipitation of metal hydroxides during the electrodialysis, the brine is...
It was shown that polyamic acids form similar complexes with aprotic solvents. The isomeric composition of PMA complexes was investigated and isomerization of PMA in solution under mild conditions was observed.DOI: 10.1002/actp.1984.010350410 被引量: 15 ...
