Reacts with moisture to give phthalic acid, which can corrode metals liberating hydrogen. Avoid dust formation and control ignition sources. Employ grounding, venting and explosion relief provisions in accord with accepted engineering practices in any process capable of generating dust and/or static electricity.
Exposure to higher concentrations of phthalic anhydride in air (1.63 +/- 0.13 mg/cu m, n=2) resulted in a body load of phthalic acid which was not totally cleared overnight, and with pre-shift phthalic acid concentrations in the urine with a mean value three times the mean control value (1.02 +/- 0.25 umol/mmol creatinine).
Phthalic anhydride is used in the preparation of primary amines. It is used as a precursor to prepare anthraquinone, phthalein, rhodamine, phthalocyanine, fluorescein and xanthene dyes. It serves as an important intermediate in the plastics industry, dyes, resins and pigments.

However, phthalic anhydride hydrolyzes rapidly in water with a half-life of about 25 minutes or less at 25\u00b0C(1,2), and biodegradation test results may be reflective of biodegradation of phthalic acid which is the hydrolysis product of phthalic anhydride(1,2). Phthalic anhydride, present at 100 mg/L, reached 85.2% of its theoretical BOD in ...
