A Greener Route for Synthesis of Fly Ash Supported Heterogeneous Acid Catalyst was written by Malpani, Sakshi Kabra;Rani, Ashu. And the article was included in Materials Today: Proceedings in 2019.Synthetic Route of C9H10O3 This article mentions the following:
Fly ash, a solid byproduct obtained from coal-fired thermal power plants, is basically a silico-aluminate material having varying minor amounts of other metal oxides. For suitable bulk utilization of this solid waste, a novel kind of solid acid catalyst has been successfully synthesized by employing microwave assisted greener route. For enhancing the efficacy, amorphous silica was extracted from fly ash in a cost-effective manner which was further chem. activated with H2SO4. Various anal. techniques were utilized to study physico-chem. properties of the as-prepared catalyst, while the catalytic activity was tested by a serious of microwave assisted esterification and Friedel-Crafts alkylation reactions under optimized reaction conditions. Higher yield of products attributes to the presence of significant number of Bronsted acidic sites on catalyst, also proved by Pyridine adsorbed FT-IR spectrum of catalyst. The catalyst was recovered and reused up to five reaction cycles with similar competence as in first run which deliberates its stability during the course of reaction. In the experiment, the researchers used many compounds, for example, Ethyl 2-hydroxybenzoate (cas: 118-61-6Synthetic Route of C9H10O3).
Ethyl 2-hydroxybenzoate (cas: 118-61-6) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Synthetic Route of C9H10O3
