Solicitudnorte

a.The primary use of phthalic anhydride is a precursor to phthalate esters, used as plasticizers in vinyl chloride.

b.Quinoline Yellow SS is a popular dye derived from the condensation of phthalic anhydride and 2-methylquinoline.

Phthalic anhydride is widely used in industry for the production of certain dyes.

c.Pharmaceuticals.Phthalic anhydride treated with cellulose acetate gives cellulose acetate phthalate (CAP), a common enteric coating excipient that has also been shown to have antiviral activity. Phthalic anhydride is a degradation product of CAP.

Seguridad

The most probable human exposure to phthalic anhydride is through skin contact or inhalation during manufacture or use. Studies show that exposure to phthalic anhydride can cause rhinitis, chronic bronchitis, and asthma. Phthalic anhydride’s reaction on human health is generally an asthma–rhinitis–conjunctivitis syndrome or a delayed reaction and influenza-like symptoms and with increased immunoglobulin (E and G) levels in the blood.
