Phthalate derivatives with low estrogenic activity, high IR spectrum signals, high Raman characteristic vibration spectrum, high fluorescence intensity, and high UV sensitivity were selected as precursors from our previous studies, so that the changes in their toxicity and estrogenic activity during biol. metabolism, ozone oxidation, photocatalytic degradation, photodegradation, and microbial degradation could be studied. The transformation pathways of these derivatives were simulated, and the reaction energy barriers were calculated To determine the potential environmental risks of these phthalate derivatives, the pharmacophore models of biotoxicity and estrogen activity of phthalates were used to predict the biotoxicity and estrogen activity of the transformed products. The results showed an increase in the biotoxicity and estrogen activity of the biometabolites, ozonization products, photocatalytic degradation products, and microbial degradation products; the only products that did not follow this trend were the photodegradation products. Notably, the pathways that produced more potentially toxic compounds were the less favorable paths. Our results indicate that the transformation products of the designed environmentally friendly phthalate derivatives potentially pose environmental risks. To avoid such risks, the environmental transformation pathway of these derivatives should be simulated to screen for environmentally friendly phthalate mols.

Ethyl 2-hydroxybenzoate (cas: 118-61-6) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Recommanded Product: 118-61-6
