sulphuric acid acts as a dehydrating agent.all carbohydrates are dehydrated to give dehydration products. For example, pentoses give furfural as dehydration product where as hexoses give 5-hydroxy furfural.. these are attacked by 1-napthol to give a purple coloured condensation product...

Furfural is furan-2-carboxaldehyde, a heterocyclic aldehyde. A colorless, sweet-smelling, mobile liquid, C4H3OCHO, made from corncobs and used in the synthesis of furan, as a solvent for nitrocellulose, and as a fungicide and weed killer.
No. It is an aldehyde. Furfural is furan-2-carboxaldehyde.
This process is the identification of carbohydrates. One may draw the structure of the adduct two molecules of resorcinol with 1 molecule of furfural to obtain carbohydrates.

ever heard of a molitov?
What is the chemical reaction for furfural and a primary aromatic amine C5H4O2 plus Nh2?y
Our company is an overseas department of Spring Strength Group, who is the earliest specialized manufacturer of furfural in China. With annual productivity of 5,000 MT, our factory manufacture a mass of furfural with content of 99%,98.5%.For the advantages of low-price, high-quality and good-service, our products have long enjoyed a great fame both at home and abroad and we are in the belief that you will be pleased with them.
