Abstract:
Ethanol has emerged as a promising renewable feedstock for chemicals and sustainable fuel production. Its conversion into ethylene, diethyl ether, and higher-value chemicals through dehydration over catalysts relies on carefully designed catalysts to enhance activity, selectivity, and stability. This review critically examines the catalytic transformation pathways leading to key petrochemical intermediates such as ethylene, propylene, and 1,3-butadiene. It places special emphasis on solid acid catalysts, modified oxides, zeolites, and heteropoly acids, highlighting recent advances in catalyst design, including surface modification, morphology control, and nanostructuring. The review also discusses mechanistic insights, reactor engineering, and strategies to overcome coke formation and catalyst deactivation. Finally, it explores future perspectives on integrating bioethanol into petrochemical supply chains, focusing on challenges related to catalyst performance, process scalability, and sustainable chemical production.

Ethers from Alcohols: Alcohol Dehydration and Williamson Ether Synthesis
Ethers can be prepared from organic compounds by various methods. Some of them are discussed below,
Preparation of Ethers by Alcohol Dehydration
In this method, in the presence of protic acids, alcohol dehydrates to produce alkenes and ethers under different conditions. For example, in the presence of sulphuric acid, dehydration of ethanol at 413 K yields ethoxyethane, whereas it yields ethene at 443 K.
Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...

Reduction of Alkenes: Catalytic Hydrogenation
Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.
The hydrogenation process takes place on the...
Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.
