Abstract:
This work is described through a one-pot three-component reaction of o-phenylenediamine, and dimedone, under reflux conditions in aqueous ethanol/H2O (1 : 1 v/v, 5 mL) in the presence of GO@tannic acid-TTE. The main advantages of this method are the ease of operation, purification, and the absence of hazardous and expensive solvents and catalysts. Also, this catalyst has the ability to perform this reaction in large quantities on an industrial scale. FT-IR, TGA, XRD, EDX, elemental mapping, TEM, and SEM methods have been used to characterize the prepared nanocatalyst. The catalyst can be reused several times.

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.
