Balaji Santhanam. This colorless solid is an important industrial chemical, especially for the large–scale production of plasticizers for plastics. Empirical Formula (Hill Notation) C 8 H 4 O 3. Search for more papers by this author. Phthalic anhydride is the organic compound with the formula :-C6H4(CO)2O. Phthalic anhydride has another major use in the production of polyester resins and other minor uses in the production of alkyd resins used in paints and lacquers, certain guys, insect repellents, and urethane polyester polyols. Hydrolysis of anhydrides is not typically a reversible process. [11] Phthalic anhydride is a degradation product of CAP.[12]. In 2000, the worldwide production volume was estimated to be about 3 million tonnes per year.[4]. Phthalic acid is an aromatic dicarboxylic acid, with formula C 6 H 4 (CO 2 H) 2.It is an isomer of isophthalic acid and terephthalic acid.Although phthalic acid is of modest commercial importance, the closely related derivative phthalic anhydride is a commodity chemical produced on a large scale. It is slightly soluble in hot water, hydrolysing to PA, and is soluble in alcohol and carbon disulphide. Beilstein/REAXYS Number 118515 . NACRES NA.21 It was discovered in 1871 by Adolf von Baeyer. The phthalic acid is somewhat soluble in water. Availability. Logistics services are available in the United States. University of Georgia, Athens, GA 30602. Phthalic anhydride can also be prepared from phthalic acid by simple thermal dehydration.[4]. Phone : + 91 - 04172 - 244441 / 244442 / 244446 Fax : + 91 - … 2.01.2.2.2 Anhydrides. Encyclopedia of Reagents for Organic Synthesis. : 85-44-9 1.2 Relevant identified uses of the substance or mixture and uses advised against Identified uses : Laboratorychemicals, Industrial & for professional use only. Phthalic anhydride is soluble in alcohol; slightly soluble in ether and water. PA is soluble in alcohol and carbon disulphide. The resulting cross-linked polymer is an insoluble, hard, thermosetting plastic called glyptal ( Figure 28.12 ). Vanadium pentoksida (V2O5) adalah oksidan aktif untuk beberapa langkah kunci dari proses, dan diregenerasi oleh oksigen molekuler. Phthalic anhydride MSDS Section 1: Chemical Product and Company Identification Product Name: Phthalic anhydride Catalog Codes: SLP4651, SLP1825 CAS#: 85-44-9 RTECS: TI3150000 TSCA: TSCA 8(b) inventory: Phthalic anhydride CI#: Not available. Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed.) Incompatible with acids, strong oxidizing agents, alcohols, amines, and bases. Phthalic anhydride is used in the synthesis of primary amines, the agricultural fungicide phaltan, and thalidomide. If breathed in, move person into fresh air. Chiral alcohols form half-esters (see above), and these derivatives are often resolvable because they form diastereomeric salts with chiral amines such as brucine. Phthalic anhydride itself is used as a monomer for synthetic resins such as glyptal, the alkyd resins, and the polyester resins. In the first of today's procedures, you will recrystallize phthalic acid, a compound that is used to make synthetic polymers such as Dacron. Phthalic anhydride is a common laboratory chemical, Pthalic anhydride has been shown to be esterified with primary alcohols at room temperature. 100% Phthalic Anhydride 85‐44‐9 4. C 6 H 4 (CO) 2 O + H 2 O → C 6 H 4 (CO 2 H) 2. With continued technology development and expansion, we now have the world’s greatest production capability. Varma, V.B.
