Production of Magnesium Chloride: An Overview
Published in Hussein K. Abdel-Aal, Magnesium, 2019
Magnesium chloride is a compound that has six moles of water of hydration, written as MgCl2∙6H2O; that is attached to the polar Mg-Cl molecule as a result of intermolecular attractions. Therefore, the water molecules cannot be removed easily due to intermolecular attractions exhibited by this structure.

Chemical additives, such as lime, cement, and pozzolanic materials, are commonly used to improve soil properties (Aiban 1994; Goodarzi and Salimi 2015; Mitchell 1970; Vyas, Phougat, and Sharma 2010), and the stabilization mechanisms of these traditional stabilizers represent harm. However, these calcium-based soil stabilizers are harms to the environment because the production of cement produces approximately 1.0 t of CO2 for per ton of ordinary Portland cement (OPC). Hence, many researchers have explored non-calcium-based soil stabilizers (Al-Khanbashi and Abdalla 2006; Liu et al. 2011; Liu 2007; Naeini, Naderinia, and Izadi 2012; Ou, Zhang, and Yi 2011). One of the new stabilizers is hexahydrate magnesium chloride (MgCl2·6H2O), which has been used as a green stabilizer as compared to the calcium-based stabilizer. When magnesium chloride (MgCl2) solution is used in road and pavement industries, it stabilizes the road material, controls dust, and de-ices roads in cold regions. Furthermore, it can prevent vehicle corrosion, reduce asphalt, and cement pavement damage, and protect plants and organisms. (Canada 2001; Goodrich, Koski, and Jacobi 2009; Singh, Piechota, and James 2003).
