Chemical reaction of Furfural 99.5%min CAS 98-01-1
Because furfural has aldehyde and dienyl ether functional groups, furfural has the properties of aldehydes, ethers, dienes and other compounds, especially similar to benzaldehyde. Under certain conditions, furfural can undergo the following chemical reactions:
1. Furfural is oxidized to maleic acid, maleic anhydride, furoic acid and furan formic acid.
2. Under the condition of gas phase, furfural is oxidized by catalyst to produce dehydrated malic acid.
3. Furfural hydrogenation can produce furfuryl alcohol, tetrahydrofuran, methylfuran and methyltetrahydrofuran.
4. Furan can be prepared by decarburizing furfural steam and steam with appropriate catalyst.
5. Under the action of strong base, furfural reacts with konicharo to produce furfuryl alcohol and sodium furoate.
6. Furfural can undergo berqin reaction under the action of fatty acid salt or organic base to condense with anhydride to produce furan acrylic acid.
7. Furfural condenses with phenolic compounds to form thermoplastic resin; Condensation with urea and melamine to produce plastics; Furfural ketone resin was prepared by condensation with acetone.
