G. Bratulescu, Cyclisation under the action of the microwaves of the D-saccaric acid to 2,5-furandicarboxylic acid, REV RO CHIM, 45(9), 2000, pp. 883-885
A new and simple method for D-saccharic acid cyclisation to 2,5-furandicarb
oxylic acid is reported. The cyclisation is achieved with benzenesulfonic a
cid and microwaves both in dry medium.
