The classic example of a dehydration reaction is the Fischer esterification, which involves treating a carboxylic acid with an alcohol to give an ester Often such reactions require the presence of a dehydrating agent, i.e. a substance that reacts with water.
Two monosaccharides, such as glucose and fructose, can be joined together (to form saccharose) using dehydration synthesis.
Ketene is produced by heating acetic acid and trapping the product:[1] Alkenes can be made from alcohols by dehydration.
3-Hydroxylcarbonyls, called aldols, release water upon standing at room temperature: The reaction is induced by dehydrating reagents.
Plaster of Paris is produced by dehydration of gypsum in a kiln:[10][11] The resulting dry powder is ready to be mixed with water to form a stiff but workable paste that hardens.
