The use of nano-silica melamine trisulfonic acid as a reusable heterogeneous solid acid catalyst in the esterification reaction of carboxylic acids and alcs. is reported. The reaction conditions were optimized by testing temperature, each component of catalyst, feedstock ratios as well as load of catalyst. The synthesized catalyst was characterized by X-ray diffraction, SEM, Fourier transform IR spectroscopy, and thermogravimetric anal. techniques. The results showed that nano-silica melamine trisulfonic acid was an efficient dehydrating agent in the condensing reactions between different kinds of aliphatic and aromatic carboxylic acids and alcs. The method was simple, rapid, straightforward, catalyst reusability, and holds potential for further application in acid-catalyzed organic synthesis and industrial requirements. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1COA of Formula: C10H20O2).
Octyl acetate (cas: 112-14-1) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
