About Phthalic Anhydride. Phthalic Anhydride (a.k.a. PHTAN) is the anhydride of phthalic acid. It was the first anhydride to be used commercially. It appears as a colorless or white solid in the form of needles or platelets and it has a characteristic odor, being toxic if inhaled. When mixed with water, it forms a corrosive solution. It is mainly used to produce plasticizers.
Phthalic Anhydride must be stored separated from combustible substances, strong oxidants, reducing substances, strong acids, and bases. It should be stored in a cool and ventilated area out of direct sunlight and away from ignition sources and heat. Shipment of Phthalic Anhydride is made preferably in the molten form of the product. Insulated and heated tanks are used, as are insulated rail tank cars and tank trucks. Rail tank cars can hold about 84 t, and trucks about 20 t. The molten form can be handled and pumped in bulk form, and as a result, is priced lower than the solid. Solid Phthalic Anhydride is available as a flake in 1 t and 0.5 t super sacks, and 22.7 kg multiwall bags.
Raw materials and the respective production processes employed in the manufacturing of Phthalic Anhydride are listed below.
- o-Xylene (gas-phase air oxidation)
- Naphthalene fraction (gas-phase air oxidation)
The uses and applications of Phthalic Anhydride may vary according to its specification. The main forms of Phthalic Anhydride are technical grade (5 to 8% moisture) and pure (99.8% minimum purity).
Phthalic Anhydride is mainly used as an epoxy resin curing agent and vulcanization retarder. It can also be used as an intermediate in chemical resins, dyes, and pigment production. This commodity can be used in the manufacture of derivatives, such as: dioctyl phthalate; phenolphthalein; unsaturated polyester resin; o-benzoylbenzoic acid; phthalimide
