Phthalic Anhydride

Phthalic Anhydride Manufacturer

Xinnuo is a mainstay of the phthalic anhydride (PA) industry as a leading PA producer. Over the past 20 years, based on its advantages and seizing opportunities, Xinnuo Lixing has successively built production facilities such as tar processing and deep processing of phthalic anhydride.

The main Phthalic Anhydride plant production capacity is 80,000 tons/year of naphthalene phthalic anhydride
Phthalic anhydride industry chain: Phthalic anhydride, as an important organic chemical intermediate, can be used not only in the manufacture of environmentally friendly plasticizers, and resin production but also in the preparation of new degradable plastics. This project belongs to the comprehensive utilization of carbon dioxide that the state encourages to develop. New material project.

Phthalic anhydride is a white solid flake or molten liquid with the molecular formula C8H4O3, the main form of phthalic acid, and an important industrial chemical for plasticizers.

Appearance: Phthalic anhydri de, white needle shaped crystal s or flake-shaped crystals.

Solubility: Easily sublimated, slightly soluble in col d water, soluble in hot water to be hy drolysed into phthal ate; soluble in alcohol, benzene and pyridine, slightly soluble in ether

Main Use: Alkyd and polyester resins for coating applications, plasticizers (phthalates) for plastics (PET), synthetic lubricants, agricultural fungicides, pharmaceuticals and pesticides.

Xinnuo is one of the largest Chemical Phthalic Anhydride Manufacturers in China.

Xinnuo is handling the storage, transport, export & import formalities of Phthalic Anhydride globally.

Packing: Plastic bag lined woven bag, Net wt 25kg

phthalic anhydride (PA) is a white solid crystalline compound in various forms or a clear molten liquid, with an irritating odor. It is slightly soluble in hot water, hydrolysing to Phthalic Acid. PA is soluble in alcohol and carbon disulphide. It reacts with strong oxidants and responds violently when heated with copper oxide or sodium nitrite, to cause an explosion hazard.

Phthalic anhydride is presently obtained by catalytic oxidation of ortho–xylene or naphthalene. When separating the phthalic anhydride from production by products such as o–xylene in water, or maleic anhydride, a series of “switch condensers” is required. Phthalic anhydride can also be prepared from phthalic acid.

Phthalic anhydride is a precursor to a variety of reagents useful in organic synthesis. Important derivatives include phthalimide and its many derivatives.

Phthalic anhydride is widely used in industry for the production of certain dyes. A well-known application of this reactivity is the preparation of the anthroquinone dye quinizarin by reaction with para–chlorophenol followed by hydrolysis of the chloride.

One of the main uses of phthalic anhydride is the production of “phthalate” plasticizers such as Vestinol 9 DINP (DiIsoNonyl Phthalate) which are used to produce flexible PVC (Vinyl) products. These include, but are not limited to Wire & Cable applications, coated fabrics, roofing membranes and swimming pool liners.
