Patient's question:
NoDoctor's answer:
Under the action of a catalyst, oxygen-containing reactants undergo dehydration within or between molecules to form new compounds.For example, 2-phenylethanol dehydrates to styrene on Al2O3. Lower or higher alcohols dehydrate to alkenes or ethers on zeolites. Organic acids react with ammonia to form nitriles on H3PO4/diatomaceous earth. Butanediol dehydrates to butanediol on zeolites. Alcohols react with ammonia to form amines on Al2O3/SiO2, etc.
