We have investigated the influence of the structure of oxide surfaces on the thermal stability of anchored phthalic acid (PA) thin films. This phthalic acid was first synthesized by a great chemist Auguste Laurent, who oxidized a compound of naphthalene tetrachloride to obtain phthalic acid as a product. Other names: 1,3-Isobenzofurandione; ESEN; Phthalandione; Phthalic acid anhydride; Retarder AK; Retarder ESEN; Retarder PD; TGL 6525; Vulkalent B/C; 1,2-Benzenedicarboxylic anhydride; 1,3-Phthalandione; 1,2-Benzenedicarboxylic acid anhydride; 1,3 … organic-chemistry reactivity. Abstract We have performed a model study to explore the influence of surface structure on the anchoring of organic molecules on oxide materials. Phthalic acid, also called 1, 2-benzenedicarboxylic Acid, colourless, crystalline organic compound ordinarily produced and sold in the form of its anhydride. 603-11-2. UnitPot is a noteworthy web-based scientific unit converter that comes with an intuitive user interface. S3F) , and placed in the middle layer of the box (gray color in Fig. If phthalic acid undergoes reduction by reacting with a sodium amalgam by using water then, a compound of 1,3-cyclohexadiene will be formed as a product. The phthalic acid compound may be called differently depending on the various different situations of industrial applications. TrY iS CheM . are all the other names by which phthalic acid is known. Singh N(1), Dalal V(1), Kumar P(2). o-Phthalic acid molecules act as bridge between two Cu(II), one carboxylate binds to … It is an isomer of isophthalic acid and terephthalic acid. Phthalic acid has a chemical formula C 6 H 4 (CO 2 H) 2 and comprises a six-carbon benzene ring with two carboxylic acid … Phthalic acid has low toxicity of 550 mg/kg. Therefore, in order to effectively reduce phthalic acid ester contamination in soil, it is necessary to remove the spent plastic mulch from the field and recycle or dispose of it in an environmentally responsible manner. The radius of the spheres is therefore smaller than the rod lengths in order to provide a clearer view of the atoms and bonds throughout the chemical structure model of phthalic acid. Molecular Formula C 8 H 6 O 4, molecular weight 166.13.A colorless crystal. Among the EDCs, phthalic acid esters ... A single-layer graphene periodic structure with size of 19.67 Å × 34.08 Å × 3.400 Å was constructed as the model compound of MCB (Fig. The chemical formula of phthalic acid was found to be C₈H₆O₄. It is too early to say whether small differences in atomic positions found so far are significant. The common name is derived from the turpentine-producing tree Pistacia terebinthus and phthalic acid. Structure of the carboxyl acid group. “Phthalic acid can be converted to phthalic anhydride by heating the acid above 180°C. Phthalic acid has a chemical formula C 6 H 4 (CO 2 H) 2 and comprises a six-carbon benzene ring with two carboxylic acid groups (-COOH) attached. 2013b). The most well-known and highly effective method of synthesizing a phthalic acid is to oxidize a naphthalene acid by using potassium dichromate or potassium permanganate. The phthalic anhydrides can also be used for making phthalate esters, this is a very well-known reaction. A benzenedicarboxylic acid carrying carboxy groups at positions 1 and 4. 166.131; All; Links to Resources; Names & Synonyms; … Chronic toxicity and carcinogenicity studies of several phthalic acid esters (PAEs) and compounds containing a 2-ethylhexyl moiety were conducted in Fischer 344 rats and B6C3F1 (hybrid) mice. It acts similar to ordinary table sugar, which decomposes when Phthalic acid Guidechem provides Phthalic acid chemical database query, including CAS registy number 88-99-3, Phthalic acid MSDS (Material Safety Data Sheet), nature, English name, manufacturer, function/use, molecular weight, density, boiling point, melting point, structural formula, etc. Acids accelerate the reaction with water. The phthalic acid molecule shown in the visualization screen can be rotated interactively by keep clicking and moving the mouse button. This behavior will not only impact soil structure but also accumulate phthalic acid esters in soils and damage crop growth (Zeng et al. Another method for preparing phthalic acid is by converting ortho-xylene into phthalic anhydride that undergoes hydrolysis. AutoDock 4.2.6 was used to perform the docking of PAEs with hACMSD . Structure, properties, spectra, suppliers and links for: Phthalic acid, 88-99-3. X-ray crystal structure shows structure with monoclinicP2 1/cspace group.o-Phthalic acid molecules act as bridge between two Cu(II), one carboxylate binds to one Cu(II) as bidentate while the other carboxylate binds to another Cu(II) as monodentate. Author information: (1)Department of Biotechnology, Indian Institute of Technology Roorkee, 247667, India. Terephthalic acid is an organic compound with formula C 6 H 4 (CO 2 H) 2.This white solid is a commodity chemical, used principally as a precursor to the polyester PET, used to make clothing and plastic bottles.Several million tonnes are produced annually. Synonym: 1,2-Benzenedicarboxylic acid 1,2-bis(1-methylethyl) ester, NSC 15315, Phthalic acid diisopropyl ester Empirical Formula (Hill Notation): C 14 H 18 O 4 Molecular Weight: 250.29 My teacher told me that among the following compounds only compound 3 will form phthalic acid when reacting with hot $\ce{KMnO4}$. The IUPAC name given to phthalic acid is Benzene-1,2-dicarboxylic acid. Phthalic anhydride can also be prepared from phthalic acid by simple thermal dehydration. Molecular docking of ligands . The phthalic acid product is separated from toluic acid which is added to fresh xylene and catalyst and charged to the oxidation step.
