  • What is diethyl phthalate?
  • Diethyl phthalate (DEP) is a member of the group of esters of phthalic acid known as phthalates, used ubiquitously as solvents and plasticisers worldwide. DEP can increases the flexibility of plastics. It is also contained in deodorant formulations, perfumes, emollients and insect repellents. It can cross react with dimethyl phtalate.
  • How do you store diethyl phthalate?
  • Diethyl phthalate for synthesis. CAS 84-66-2, pH 7 (H₂O, 20 °C). Relatively unreactive organic reagents should be collected in container A. If halogenated, they should be collected in container B. For solid residues use container C. Store below +30°C. Diethyl phthalate for synthesis. CAS 84-66-2, pH 7 (H₂O, 20 °C).
  • Is diethyl phthalate flammable?
  • Non flammable Diethyl phthalate is used as a plasticizer for film coatings on tablets, beads, and granules at concentrations of 10–30% by weight of polymer. Diethyl phthalate is also used as an alcohol denaturant and as a solvent for cellulose acetate in the manufacture of varnishes and dopes.
  • Is diethyl phthalate miscible?
  • It is miscible with ethanol and ethyl ether. Diethyl phthalate is soluble in acetone, benzene, carbon tetrachloride, alcohols, ketones, esters, and aromatic hydrocarbons and partly miscible with aliphatic solvents. Diethyl phthalate, when exposed to heat, decomposes and emits acrid smoke and irritating fumes.
  • What does diethyl phthalate taste like?
  • Diethyl phthalate is produced in the reaction of phthalic anhydride with ethanol in the presence of concentrated sulphuric acid catalyst. Clear, colorless, oily liquid with a mild, chemical odor. Bitter taste. Virtually odorless when pure ("Perfumery grade" of commercial Diethyl phthalate). Very bitter taste in weak hydro-alcoholic solution.
  • What is a second-order rate constant for hydrolysis of diethyl phthalate?
  • A second-order rate constant of 2.5 x 10 -2 /M?sec was reported for the hydrolysis of diethyl phthalate at 30 °C and pH 8 (Wolfe et al., 1980). At 30 °C, hydrolysis halflives of 8.8 and 18 yr were reported at pH values 9 and 10 -12, respectively (Callahan et al., 1979).
