  • What is diethyl phthalate?
  • Diethyl phthalate is produced by the reaction of ethanol with phthalic anhydride, in the presence of a strong acid catalyst: It finds some use as a specialist plasticiser in PVC, it has also been used as a blender and fixative in perfume.
  • Does diethyl phthalate sink in water?
  • Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?) Diethyl phthalate (DEP) is a phthalate ester. It occurs as a colourless liquid without significant odour but has a bitter, disagreeable taste. It is more dense than water and insoluble in water; hence, it sinks in water.
  • Why are phthalates used as plasticizers?
  • Phthalates are widely used as plasticizers in many industrial products due to their chemical properties that confer flexibility and durability to building materials, lubricants, solvents, insect repellents, clothing, cosmetics, being widely distributed in the environment.
  • How to extract phthalate acid esters from sediment samples?
  • To extract phthalate acid esters (PAEs) from the sediment samples, 1 g of dry and homogeneous samples of sediments was placed into clean centrifuge tubes. Thereafter,10 mL of acetone/n-hexane solution (v/v 1:1) was added.
  • What is phthalic acid used for?
  • It finds some use as a specialist plasticiser in PVC, it has also been used as a blender and fixative in perfume. Biodegradation of DEP in soil occurs by sequential hydrolysis of the two diethyl chains of the phthalate to produce monoethyl phthalate, followed by phthalic acid.
  • Why are phthalates used in industrial products?
  • Phthalates are anthropogenic compounds widely used in many industrial products due to their chemical properties that confer flexibility and durability to building materials, lubricants, solvents, insect repellents, clothing, cosmetics.
