A low cost and environmentally friendly process for the synthesis of disodium salt of hydroquinone (DSH) is presented. This novel synthesis technique employs water as solvent. Compared to the well-established synthesis techniques which utilize methanol, the presented technique is safer and environmentally friendly. First, a DSH sample is synthesized using the customary synthesis technique employing methanol as solvent. Then, the technique introduced in this study is implemented under three different scenarios differing in the way the drying step is performed. The resulting DSH powders are then compared using FTIR analyses. It is shown that all the synthesis techniques yield acceptable results, However, drying at higher temperatures yield better results. Furthermore, the crystal structure of the DSH sample is investigated using an XRD analysis and compared to the simulated diffraction pattern of DSH. The results indicate the correct synthesis of DSH. Finally, a DSC-TGA test is performed to further confirm the correct synthesis of DSH.
