Ans- Furfural is a heterocyclic aldehyde that is used as a raw material in the production of various furan-based chemicals such as methyl furan, furfuryl alcohol, tetrahydrofurfuryl alcohol, tetrahydrofuran, furoic acid, dihydropyran, etc. It has two major functional groups, an aldehyde and two olefin groups making it a versatile compound to be used for many applications. Reactions such as acylation, acetylation, reductive amination, reduction to alcohols, decarboxylation, oxidation to carboxylic acids, Grignard reaction, and aldol reaction occur through the aldehyde functional group. Reactions such as alkylation, hydrogenation, oxidation, halogenation, open ring reactions, and nitration are carried out through the furan ring system. Furfural undergoes an oxidation reaction to convert into furoic acid.It undergoes hydrogenation to produce furfuryl alcohol.It forms 2-Methyl furan during decarbonylation.Furfural upon hydrogenation performs tetrahydrofuran.It undergoes reductive amination to form furfuryl amine.On decarboxylation, furfural converts into furan.
