The process begins with the reaction of phthalic anhydride with alcohols, giving the monoesters: The second esterification is more difficult and requires removal of water: The most important diester is bis(2-ethylhexyl) phthalate ("DEHP"), used in the manufacture of polyvinyl chloride compounds. Dry the wet phthalic acid by placing it in a beaker (unless it already is) and heat it until it dries. 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. Get medical attention. Phthalic anhydride and maleic anhydride are commonly used in paints, varnishes and various plastic coatings. Phthalic acid is very soluble in boiling water, 18 g/100 mL, and is much less soluble in chilled (14°C) water, 0.54 g/100 mL. Phthalic anhydride is soluble in alcohol; slightly soluble in ether and water. The phthalic acid is somewhat soluble in water. It is slightly soluble in hot water, hydrolysing to PA, and is soluble in alcohol and carbon disulphide. It is both an irritant and sensitizer of the skin and respiratory tract, and may produce asthma on repeated exposure. "Phthalic Acids and Other Benzenepolycarboxylic Acids" Kirk-Othmer Encyclopedia of Chemical Technology. Phthalic acid is however easily dehydrated to form phthalic anhydride. Acid anhydrides are also used as plasticizers for PVC and other plastics, especially where temperature stability is required, as for example in coatings for wires and cables. If breathing is difficult, give oxygen. Phthalic anhydride is very slightly soluble in H2O, soluble in alcohol, and slightly soluble in ether. It can also be produced by ammoxidation of o-xylene. Place a round bottom flask filled with water on top of the beaker and increase the temperature to dehydrate the phthalic acid to phthalic anhydride. TETRABROMOPHTHALIC ANHYDRIDE reacts exothermically with water. Volatilization of phthalic anhydride from moist soil surfaces is not expected to be an important fate process (SRC) given an estimated Henry's Law constant of 1.7X10-8 atm-cu m/mole (SRC) based upon its vapor pressure, 5.17X10-4 mm Hg (5), and water solubility, 6000 mg/L (6).

Phthalic anhydride is also used as a precursor of anthraquinone, phthalein, rhodamine, phthalocyanine, fluorescein, and xanthene dyes. : 85-44-9 MSDS SECTION 1: Identification of the substance/mixture and of the company/undertaking Phthalic anhydride is a common laboratory chemical, Pthalic anhydride has been shown to be esterified with primary alcohols at room temperature. The phthalic acid is somewhat soluble in water. EPA has determined that phthalic anhydride is a Rute yang lebih kontemporer termasuk oksidasi naftalena atau orto-xilena. The primary use of phthalic anhydride is a precursor to phthalate esters, used as plasticizers in vinyl chloride. Phthalic anhydride is the organic compound with the formula C 6 H 4 (CO) 2 O. Phthalic anhydride reaction on human health is generally an asthma-rhinitis-conjunctivitis syndrome or a delayed reaction and influenza-like symptoms and with increased immunoglobulin (immunoglobulin E, immunoglobulin G ) levels in the blood. If breathing is difficult, give oxygen. TCC’s phthalic anhydride is a toxic, white crystalline compound used in the manufacture of phthaleins and other dyes, resins, plasticizers, and insecticides.
