- Abstract
Studies related to biomass are increasingly highlighted, since it is a renewable, sustainable, and abundant source of carbon, with the potential to replace oil and its derivatives. Several compounds are targets of research in this area, among which we can highlight 5-hydroxymethylfurfural (HMF), since it is a chemical platform that can be chemically transformed into a series of useful products, including biofuels. In this work fructose is converted to HMF with 74% yield and isolated with purity greater than 97%, employing a biphasic system (water/NaCl and ethyl acetate), using 1 mol% of p-sulfonic acid calix[4]arene (CX4SO3H)) as the organocatalyst, 140 °C, 10 min under microwave irradiation (MWI, 75 W). The aqueous phase (water/NaCl and CX4SO3H) was recyclable for five reaction cycles, with no significant drop in yields. In addition, the ethyl acetate recovered can be recovered at the end of the process, making it reusable. Therefore, with the methodology developed, it was possible to obtain the HMF in a recyclable, clean, sustainable system and in accordance with green chemistry.
