♦Phthalic Anhydride TDS
♦Phthalic Anhydride MSDS
Product description
♦Product name :Phthalic Anhydride
♦CAS:85-44-9
♦Molecular formula: C8H4O3
♦molecular weight: 148.11
♦Melting point: 130.8℃
♦Water solubility: easily soluble in hot water
♦Density: 1.53 g/cm3
♦Appearance: white, needle-like crystals
♦Flash point 152 °C
Usage/Application
♦ Phthalic anhydride is one of the most important organic chemical raw materials. Its main derivatives include dibutyl phthalate; dioctyl ester and diisobutyl ester, etc., used as plasticizers for PVC, etc.; Saturated polyester resin; alkyd resin; dyes and pigments; various paints; food additives; phenolphthalein, a laxative in medicine; imithiophos in pesticides; fenamizon and sodium saccharin, etc.
♦This product is used as a curing agent for epoxy resin. This product is an important organic chemical raw material, mainly used in the production of phthalate plasticizers, coatings, saccharin, dyes and important intermediates of organic compounds, pesticides, fungicides, rubber processing aids, and photosensitive materials Wait.
♦Used as an analytical reagent. Organic synthesis intermediates. The dye industry is used to prepare important intermediates such as anthraquinone, 2-chloroanthraquinone, 1,4-dihydroxyanthraquinone, and dyes such as phthalocyanine blue BS, phthalocyanine blue BX, and phthalocyanine blue B.
♦Used as a curing agent for epoxy resin, the reference dosage is 30-50 parts by mass, and the pot life of 100g resin complex is rt/6h, 120℃/1.5h. Curing conditions: 100/2h+150℃/5h or 100℃/12h, 140℃/8h, 200℃/6h. The heat generation is small during curing, the cured product has good electrical properties and mechanical strength, and the heat distortion temperature is 110-152°C.
♦It is an important organic chemical raw material. In the synthetic resin industry, it is used to produce polyester resin, amino resin, unsaturated polyester resin, alkyd resin, etc. In the dye industry, it is used to prepare dye intermediates such as anthraquinone and chloroanthracene dihydroxyanthraquinone and dyes such as phthalocyanine blue BS, phthalocyanine blue BX, and phthalocyanine blue B. Plastics industry is used to prepare plasticizers such as dibutyl phthalate, dioctyl phthalate and their mixed esters. It is also an important intermediate for the manufacture of various drugs, paints and organic compounds.
♦Used in the manufacture of plasticizers, dibutyl phthalate, resins and dyes
Chemical Property
♦Phthalic anhydride can undergo hydrolysis, alcoholysis and ammonolysis reactions, and react with aromatic hydrocarbons to synthesize anthraquinone derivatives.
♦Phthalic anhydride is industrially prepared by vapor-phase oxidation of naphthalene and air at 350-360°C under the catalysis of vanadium pentoxide. It can also be prepared by oxidation of o-xylene with air.
♦Phthalic anhydride can be used instead of phthalic acid, and mainly reacts with monohydric alcohols to form esters, such as dibutyl phthalate and dioctyl phthalate.
Product Feature
♦Customized service of phthalic anhydride products: 1) Customized markings, which can be customized according to customer requirements, and then we will arrange production. It takes about ten days.
♦Special export services:When exporting to neighboring land-based countries (Myanmar, Vietnam, Laos, Kazakhstan, etc.), containers can be sent by train, or trucks can be used directly at the border to unload the goods and return empty.
