  • 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.
  • What methods are used to detect diethyl phthalate?
  • Rather, the intention is to identify well-established methods that are used as the standard methods of analysis. Many of the analytical methods used to detect diethyl phthalate in environmental samples are the methods approved by federal organizations such as EPA and the National Institute for Occupational Safety and Health (NIOSH).
  • 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.
  • 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.
  • How is diethyl phthalate collected?
  • Diethyl phthalate can be collected by pumping an air sample through ethylene glycol ( Thomas 1973) or directly through an activated Florisil® column ( Giam and Chan 1976 ). Measurements in air can also be done by passive sampling on charcoal, which is less expensive than active sampling but requires much longer sampling times.
  • 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.
