Phthalic Anhydride is made from phthalates or naphthalene.
It is widely used in the production of plasticizers and pigments. It can also be used as a scorch retarder, light stabilizer and heat stabilizer.
If exposed to phthalic anhydride, it may cause acute irritation to personnel, including irritation to eyes, respiratory tract and skin, but no permanent damage has been observed.
There are three ways of the phthalic anhydride production process: Ortho-xylene process, naphthaline process and mixing process.
