Mixed Oxides: Role of Washing and Residual Ions in Transesterification Reactions.

ABSTRACT: The mixed oxides (MOs) serve as catalysts for many reactions such as transesterification, transformation of ethanol to butanol, catalytic cracking, or dehydrogenation reactions. MOs are usually synthesized from hydrotalcites, which are often prepared by the coprecipitation method. However, some chemicals can remain after coprecipitation and influence the properties of MOs, including subsequent applications. The novelty lies in investigating how the residual chemicals affect the properties of hydrotalcites, MOs, and the transesterification reaction (conducted in both one- and two-step processes). Mg-Al and Mg-Fe hydrotalcites were synthesized from chloride and nitrate salts via coprecipitation with NaOH, followed by washing with varying amounts of redistilled water, resulting in variations
