Nitration: Nitration of furan is achieved with mild nitrating agents87 such as acetyl
nitrate (a mixture of acetic anhydride and nitric acid) at - 5 to - 30°C to yield 2-
nitrofuran. The reaction proceeds largely by an addition- elimination mechanism.
Furan Pyrrole Thiophene In furan and thiophene, one lone electron pair overlaps
with the n system, and the other lone pair is in the plane of the ring, perpendicular
to the aromatic sextet. With pyrrole, the N— H bond is in the plane of the ring ...

Furan itself is slightly soluble in water. It is readily available, and its commercial
importance is mainly due to its role as the precursor of the very widely used
solvent tetrahydrofuran (THF). Furan is produced by the gas-phase
decarbonylation of ...

Principles of Foundry Technology
Since the process of furan sand is expensive, it is generally restricted to core
making, but it can also be used for moulds when good finish is essential. Moulds,
especially large ones, can also be prepared in composite form, using furan sand
for ...

Furan 84 is a five-membered jr-excessive aromatic heterocycle containing one
hetero oxygen atom. It is unstable in acids, forming tars, so like pyrrole (Chapter 6
, p 182) the substrate cannot be sulfonated by sulfuric or chlorosulfonic acid.
