Dehydration of alcohols. In dehydration reactions, a molecule of water is eliminated from an alcohol molecule by heating the alcohol in the presence of a strong mineral acid. A double bond forms between the adjacent carbon atoms that lost the hydrogen ion and hydroxide group.

Answer 2

Answer:

Another method of producing propene is via syngas and ethanol. Synthesis gas (carbon monoxide and hydrogen) is used to convert bioethanol to propan-1-ol:

The reaction is catalysed by a ruthenium-cobalt complex salt.

To convert an alkene to an alkane, you must break the double bond by adding hydrogen to an alkene in the presence of a nickel catalyst, at a temperature of around 302 degrees Fahrenheit or 150 degrees Celsius, a process known as hydrogenation.
