This work aims to present two syntheses according to the green chemistry principles of Cu2(OH)PO4. The first one is a mechanochemical synthesis which 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-ray diffraction, scanning electron microscopy, infrared spectroscopy and elemental analysis. Using an analysis and evaluation scale based on green principles, the synthesis method reported in this study was compared with the traditional hydrothermal synthesis method, which was found to be a polluting process, while the synthesis method reported in this study was a clean process. It was concluded that clean processes lead to time savings, low energy costs and environmental care.
