anhydride is a white, organic, crystalline compound that is used for manufacturing resins, dyes, pigments and plasticizers
El Ouardi et al., "Modeling of photocatalytic mineralization of phthalic
acid in Ti[O.sub.2] suspension using response surface methodology (RSM)," Desalination and Water Treatment, vol.
acid (1.0 mmol), aryl amine (1.0 mmol), and L-proline (0.5 mmol) were sequentially added in ethanol (5.0 mL) into a rb (round bottom) flask to form a solution.
This happens because the composite material [M.sub.1][A.sub.3][PA.sub.6]-BT has got the bigger quantity of phthalic
In addition, the decarboxylation reaction of 2,6-NDA can form naphthalene [39,40], which can be oxidized to form phthalic
anhydride [41,42] and produced the observed phthalic
acid by hydrolysis [39,43].
acid esters (PAEs) are a class of refractory organic plasticizer compounds that are widely utilized as additives and plasticizers in a variety of polymeric products, including paints, cosmetics, and flexible plastics, such as plastic toys and containers [1-3].
Major portion of PTA wastewater comprises of benzoic acid (BA), phthalic
acid (PA), p-toluic acid (p-Tol), 4-carboxybenzaldehyde (4-CBA), and terephthalic acid (TA) with minor concentrations of the p-xylene, methyl acetate and 4-formylbenzoic acid (Kleerebezem et al., 1999).
Finally, the hydroxyl number of bio-oil was determined by the phthalic
anhydride esterification method and was found to be in the range of 1,230 to 1,427 mg KOFI/g, depending on liquefaction time.
Abstract Water-soluble hydroxyl functionalized hyperbranched polyester (WH-HP) resin was synthesized using pentaerythritol, pyromellitic dianhydride, phthalic
anhydride, and 1,1,1-tris(hydroxymethyl) propane.
aliena wood in single extraction as: 1,5-hexadien-3-yne (97.95%), phthalic
acid, butyl hexyl ester (0.61%), 2-p- nitrophenyl-oxadiazol-1,3,4-one-5 (1.43%).
Phthalates, which are esters of phthalic
acid (PAE), are the most abundant and widely distributed manmade environmental pollutants owing to their use over the last 50-60 years [23,31] and humans are exposed to them from a variety of sources throughout their lives .Within the bottling industry, bottles are produced from specific polymers depending on the volume of the container, with each bottle possessing unique characteristics such as type of dispenser and disposal, bottle strength and storage time .
