Effects of phthalic acid esters on fetal health. Phthalic acid can be used for the synthesis of synthetic agents, such as isophthalic acid (IPA), and terephthalic acid (TPA). Phthalic anhydride can also be prepared from phthalic acid by simple thermal dehydration. PAEs are ubiquitous in different environments and our daily life due to their large and widespread application. Most of the phthal- ates are plasticizers; they can be in- corporated into resins, usually poly- vinyl chloride (PVC), to impart the Phthalic Acid Phthalate Ester Bioaccumulation Factor Phthalic Anhydride High Performance Liquid Chromatogra These keywords were added by machine and not by the authors. Compound Phthalic acid, dipropyl ester with free spectra: 3 NMR, 3 FTIR, and 3 MS. Di-(2-ethylhexyl) phthalate was the major phthalic acid ester in the Mississippi River estuary, with mean levels of 0.1 μg/g (dry weight) in surface sediments, 1.0 μg/liter in river water, and 0.7 μg/liter in delta water. Phthalic acid esters (phthalates) are used as plasticizers in numerous consumer products, commodities, and building materials. 178, Issue 4056, pp. 2020;55(2):148-154. doi: 10.1080/03601234.2019.1674103. Phthalate esters are commonly used as plasticizers to impart flexibility to plastics, particularly polyvinylchloride polymers (PVCs), which have a wide variety of biomedical and other uses such as building and construction, home furnishings, cars, clothing, and food wrappings. Phthalic acid esters (PAEs) rank among the primary risk pollutants and their adverse effects may endanger the environmental balance and affect the ontogenetic development of live organisms and their body functions.

Analysis of phthalic acid esters in sea water and sea sand using polymer-coated magnetic nanoparticles as extraction sorbent J Chromatogr A. Urban sprawl worldwide warrants the use of large quantities of industrial and household products containing phthalic acid esters (PAEs) resulting in adverse impacts on the quality of aquatic life in urban watercourses. butyl isohexyl phthalate. A recent food safety concern has arisen from the unapproved use of certain phthalates in a broad range of food/nutraceutical ingredients from Taiwan [53]. See all Hide authors and affiliations.

Source; PubMed; Authors: Ivana Bajkin. Phthalic Acid Ester. As China is one of the largest consumers of phthalic acid esters, some human activities may lead to the accumulation of phthalic acid esters in soil and result in contamination. Phthalic acid esters have been used as plasticizers in numerous products and classified as endocrine-disrupting compounds. Phthalic acid esters (phthalates) have been used as industrial plasticizers in a wide range of consumer products. By Jean L. Marx. Alibaba.com offers 943 phthalic acid ester products. Soil samples were taken evenly from the top and bottom soil horizons using a zig-zag pattern. 46-47 DOI: 10.1126/science.178.4056.46 . Phthalic acid has applications in the preparation of phthalate ester plasticizers[1]. Bridgest Theeffects, overperiods from3 daysto9 monthsofadministration, ofdiets containingdi-2-ethylhexyl 44.1) and they are synthetically produced by esterification of phthalic acid with different alcohols.Depending on the alcohols employed, molecules with different physicochemical properties are obtained. Uses Phthalate esters plasticizers. Epub 2019 Oct 13.

Phthalic acid esters (phthalates) are used as plasticizers in numerous consumer products, commodities, and building materials. Phthalic Acid Esters: Biological Impact Uncertain. Bacteria that grew aerobically on dibutyl phthalate and o-phthalic acid were readily detected in the sediments and water. Some of the PAEs are also used as the vehicle for perfumes. Epub 2019 Oct 14. … Diminution of migration of phthalic acid esters in tequila beverage by the year of production J Environ Sci Health B. [Phthalic acid esters (PAEs) pollution in farmland soils: a review]. Phthalic acid esters (PAEs) are the most commonly used plasticizers which are added to provide desired flexibility and clarity to the polyvinyl chloride (PVC) plastics used in packaging, storage and delivery of food, drugs and cosmetics. This paper provided the first data on the concentration, distribution, congener profile, sources and potential risk of phthalic acid eaters (PAEs) in soil of vegetable fields from the suburbs of Xianyang city, Northwest China.

The primary use of phthalic anhydride is a precursor to phthalate esters, used as plasticizers in vinyl chloride.Phthalate esters are derived from phthalic anhydride by the alcoholysis reaction. Recent studies show that DEP, a phthalic acid ester (PAE), is enzymatically hydrolyzed to its monoesters by pancreatic cholesterol esterase (CEase) in pigs and cows. Phthalic acid is the final common metabolite of phthalic acid esters (PAEs). Phthalic acid esters (PAE) are widely used during chemical synthesis and do not form covalent linkages with products. PAEs in all topsoil samples analyzed were detected, indicating that PAEs were ubiquitously environmental contaminants. title = "Phthalic Acid Esters", abstract = "The twentieth century can as properly be called the age of organic chemistry as it can the atomic age. 2020 Jan 25;1611:460620. doi: 10.1016/j.chroma.2019.460620.
