Dibutyl phthalate solubility in water
Hydrolysis of DBP leads to phthalic acid and 1-butanol. Monobutyl phthalate (MBP) is its major metabolite. Biodegradation by microorganisms represents one route for remediation of DBP. For example, Enterobacter species can biodegrade municipal solid waste—where the DBP concentration can be observed at 1500 ppm—with a half-life of 2–3 hours. In contrast, the same species can break do… Web2 days ago · Dibutyl phthalate (DBP) one of the most widely detected phthalate esters (PAEs) in the environment, which widely used as a plasticizer in plastic packaging for food, beverages and drinking water (García-Fabila et al., 2024). It is not sufficiently bound to the product, DBP can be released into water, air, soil and food (Zeng et al., 2013).
