This step is considered as the slowest step in the mechanism of catalysts. However, the general idea behind each dehydration reaction is that the –OH group in the alcohol donates two electrons to H + from the acid reagent, forming an alkyloxonium ion. An elimination reaction is the type of reaction in which two atoms adjacent to carbon atoms are eliminated from a molecule leaving multiple bonds between the carbon atoms.

When alcohol is dehydrated, -OH group and a hydrogen atom from the next carbon atom in the chain is removed. This is a basic example of an elimination reaction. Over a few years, with the help of scientists around the world, Mark was able to create powdered alcohol and called it Palcohol. The rate is different for primary, secondary and tertiary alcohols. Here phosphoric acid is used instead of Sulphuric acid because it is much safe and produces a less messy reaction. The results 5-10 years.
