PHTALIC ANHYDRIDE (PA) is a chemical product and Arena Petro Gas is in position to supply and export it directly from ESFAHAN PETROCHEMICAL - FARABI PETROCHEMICAL - through its trading services according to the following specification and technical properties.

Phthalic anhydride is an organic compound with the formula C6H4(CO)2O. It is the anhydride of phthalic acid, which means it is formed by removing water from phthalic acid. Phthalic anhydride is a white solid that has a characteristic acrid odor, also It is an important industrial chemical that mainly use for the production of plasticizers for plastics.

Plasticizers are substances that Adde to plastics to make them more flexible, soft, and durable. They use in various applications such as PVC pipes, cables, flooring, toys, and medical devices. Phthalic anhydrides use to make phthalate esters, which are the most common type of plasticizers. Phthalate esters form by reacting phthalic anhydride with alcohols, such as ethanol or butanol.

Phthalic anhydride also use in other industries, such as:

• Paints and coatings: Phthalic anhydride use to make alkyd resins, which are synthetic polymers that use as binders and modifiers in paints and coatings. Alkyd resins improve the gloss, durability, and weather resistance of paints and coatings.
• Dyes and pigments: Phthalic anhydride use to make phthalocyanine pigments, which are organic compounds that have intense blue or green colors. They are used as colorants in inks, paints, plastics, textiles, and cosmetics.
• Pharmaceuticals: Phthalic anhydride use to make phthalimide, which is an intermediate for the synthesis of various drugs, such as thalidomide, phenytoin, and saccharin.

The technical specifications of phthalic anhydride vary depending on the manufacturer and the application. However, some common parameters that measure include:

• Purity: The percentage of phthalic anhydride in the product, usually expressed as weight percent or mass fraction. The purity of phthalic anhydride should be high enough to meet the requirements of the end use.
• Color: The appearance of phthalic anhydride, usually expressed as a color number or a color scale. The color of phthalic anhydride should be low enough to avoid affecting the quality of the final product.
• Melting point: The temperature at which phthalic anhydride changes from solid to liquid state, usually expressed in degrees Celsius or Fahrenheit. The melting point of phthalic anhydride should be within a specified range to ensure proper handling and storage.
• Moisture: The amount of water present in phthalic anhydride, usually expressed as weight percent or mass fraction. The moisture content of phthalic anhydride should be low enough to avoid hydrolysis and degradation.

The technical specifications of phthalic anhydride produced by Esfahan Petrochemical Company (EPC), Farabi Petrochemical Company (FPC), is as follows:

• | Purity | % | 99.8 min | 99.8 min | 99.8 min |
• | Color | APHA | 20 max | 20 max | 20 max |
• | Melting point | °C | 130.5-131.5 | 130.5-131.5 | 130.5-131.5 |
• | Moisture | % | 0.2 max | 0.2 max | 0.2 max |

PHTALIC ANHYDRIDE

Phthalic anhydride is a crucial industrial chemical with the formula C₆H₄(CO)₂O. It is the anhydride of phthalic acid and appears as a white, crystalline solid with a characteristic acrid odor. This compound is primarily used in the production of plasticizers, which are essential for making plastics more flexible and durable. Phthalic anhydride was first synthesized in 1836 by Auguste Laurent. The initial production methods involved the liquid-phase oxidation of naphthalene using mercury as a catalyst. Modern production techniques have evolved to use vanadium pentoxide (V₂O₅) as a catalyst in a gas-phase reaction with naphthalene or o-xylene.

Applications of PHTALIC ANHYDRIDE

Phthalic anhydride is a versatile chemical with a wide range of applications across different industries:

1. Plasticizers: The most significant use of phthalic anhydride is in the production of phthalate plasticizers, such as dioctyl phthalate (DOP) and dibutyl phthalate (DBP). These plasticizers are used to enhance the flexibility and durability of polyvinyl chloride (PVC) products.
2. Unsaturated Polyester Resins (UPR): Phthalic anhydride is a key raw material in the production of UPR, which are used in the manufacturing of fiberglass-reinforced plastics, coatings, and adhesives.
3. Alkyd Resins: Alkyd resins, made from phthalic anhydride, are used in the production of paints and coatings. These resins provide excellent durability and gloss to the finished products.
4. Dyes and Pigments: Phthalic anhydride is used in the synthesis of various dyes and pigments, including anthraquinone and phthalocyanine dyes. These dyes are widely used in textiles, inks, and coatings.
5. Pharmaceuticals: In the pharmaceutical industry, phthalic anhydride is used as an intermediate in the synthesis of various drugs and active pharmaceutical ingredients (APIs).
6. Agricultural Chemicals: Phthalic anhydride is also used in the production of certain agricultural chemicals, including pesticides and herbicides.
