On June 30, 2019, Barbosa, Sandro L.; Ottone, Myrlene; de S. Freitas, Milton; Lima, Camila D.; Nelson, David L.; Clososki, Giuliano C.; Caires, Franco J.; Klein, Stanlei I.; Hurtado, Gabriela R. published an article.Formula: C13H10O3 The title of the article was Synthesis of phenyl esters using SiO2-SO3H catalyst in conventional heating and microwave-irradiated esterification processes. And the article contained the following:
A SiO2-SO3H amorphous catalyst containing a small surface area of 115.0 m2g-1 and 1.32 mmol H+/g was prepared from fine construction sand and sodium carbonate and sulfonated with H2SO4. In a 10% (weight/weight) basis, it was very efficient for catalyzing the esterification of carboxylic acids with phenol to afford Ph esters RCO2Ph [R = H, Ph, 3-pyridyl, etc.]. The reaction processes were performed using conventional heating and under microwave irradiation The yields were higher in the microwave-irradiated esterification. The catalyst could be used for three esterification sequences in both processes. The experimental process involved the reaction of Phenyl Salicylate(cas: 118-55-8).Formula: C13H10O3
