The potential environmental impact and adverse effects of the occurrence of pesticides in the aquatic environment have raised great social and political concern, leading to their control by means of several regulations, such as the European Directive 98/83/EC. In this regard, the three neonicotinoid pesticides analyzed in this work (acetamiprid, imidacloprid, and thiamethoxam) have been included in the surface water European Watch Lists under the Water Framework Directive. This research proposes the use of terpenoid-based solvents for the extraction of the three emerging contaminants previously mentioned. An initial screening of the extraction solvents was carried out through the COSMO-RS methodol., selecting the most favorable pure terpenes, eutectic terpenoid-based and conventional solvents. Furthermore, relevant issues were exptl. analyzed, such as extraction in more realistic multicomponent mixtures together with key parametric studies covering operating temperature and matrix influence. Carvacrol, a pure terpenoid not applied before as an extraction solvent of pesticides, has been revealed as an effective and sustainable substitute for conventional solvents for the first time to the best of our knowledge. Specifically, carvacrol exhibited overall extraction yields of around 97.5% from a river water matrix at a volumetric S/F ratio of 0.1 and 303.2 K. High extraction yields from river water matrixes regardless of temperature pointed to the potential of this solvent for a wide range of industrial application. In the experiment, the researchers used many compounds, for example, 5-Isopropyl-2-methylphenol (cas: 499-75-2Computed Properties of C10H14O).
5-Isopropyl-2-methylphenol (cas: 499-75-2) belongs to alcohols. Alcohols are weak acids. The most acidic simple alcohols (methanol and ethanol) are about as acidic as water, and most other alcohols are somewhat less acidic. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Computed Properties of C10H14O
