SÍNTESIS DE HIDROXIFOSFATO DE COBRE BAJO LOS PRINCIPIOS DE LA QUÍMICA VERDE

Abstract

This work aims to present two syntheses according to the green chemistry principles of Cu2(OH)PO4. The first is a mechanochemical synthesis that was carried out with Cu3(PO4)2 and NaOH at room temperature and without solvent (principles five and six), the second one employed an aqueous suspension of copper phosphate (principle six). The products were characterized by X-rays diffraction, scanning electron microscopy, infrared spectroscopy, and elemental analysis. A scale of analysis and evaluation based on green principles was applied to compare the syntheses reported in this work with the conventional hydrothermal synthesis, resulting the latter as a polluting process and those reported in this work as clean processes. It was concluded that clean processes lead to time savings, low energy costs and environmental care.
