Generation of anticalins with specificity for a nonsymmetric phthalic acid ester
Analytical Biochemistry, 2002A set of engineered lipocalins, so-called anticalins, that bind benzyl butyl phthalate, a potential pollutant of environmental and food samples or medical plastic ware, has been generated. To this end, the synthesis of a derivative of the target analyte carrying an activatable carboxylate group at the end of an aliphatic spacer arm was established ...

Sorption and Biodegradation of Phthalic Acid Esters in Freshwater Sediments
Journal of Environmental Science and Health, Part A, 2005Pathalic acid esters (PAEs) have been used as plasticizers in many products so that they could enter the aquatic environment. Three freshwater sediments in Taiwan were selected to explore the sorption and biodegradation processes of PAEs. Results indicated that di-n-butyl phthalate (DBP) and di-2-ethylhexyl phthalate (DEHP) are the only detectable PAEs

A new phthalic acid ester fromAjuga bracteosa
Natural Product Research, 2006A new phthalic acid ester 1,2-benzenedicarboxylic acid bis(2S-methyl heptyl) ester (1) was isolated from the hexane extract of the whole plant of Ajuga bracteosa. In addition, chloroform and methanol extracts yielded neo-clerodane diterpene ajugarin-I and two iridoid glycosides, reptoside and 8-O-acetyl harpagide.

[The breakdown of phthalic acid esters by microorganisms].
Nauchnye doklady vysshei shkoly. Biologicheskie nauki, 1990The distribution in environment of phthalic acid esters classified according to their inherent toxicity, teratogenic, mutagenic properties and cancerogenic activity into a group of priority pollutants of biosphere is described in this review. The role of microbial community in degradation of phthalate esters has been demonstrated.

The lubrication of aluminum by phthalic acid esters
Wear, 1966Abstract Alloy aluminum surfaces sliding on steel were lubricated with phthalic acid esters in the thin-film region, in order to determine if the ester-aluminum reaction products would protect the aluminum surface and result in extremely low wear rates, as previously found with adipic acid esters.

[Phthalic acid esters and the human body].
Casopis lekaru ceskych, 1997Phthalic acid esters have been used for its softening and plastification effects as additives to various kinds of products: colours, paintings, glues, cosmetic products, inks, repellents, films, PVC-derived products including medical disposable PVC products. The authors present a basic review of literature on toxicologically important sources including

[Photodegradation of phthalic acid esters in water].
Sichuan da xue xue bao. Yi xue ban = Journal of Sichuan University. Medical science edition, 2004To investigate the environmental degradation process of phthalic acid esters (PAEs).The PAEs were detected by HPLC. We used the system of ultraviolet light, TiO2 and hydrogen peroxide to promote the photodegradation of PAEs in water.The photodegradation of PAEs was consistent with the first level kinetics.
