Description
Di-n-pentyl phthalate is a colorless oily liquid. Sp.Gr. 1.02. B.P. approximately 350℃. Insoluble in water.
Chemical Properties
clear colorless viscous liquid
Uses
Di-n-pentyl phthalate is a plasticizer for PVC membrane electrodes.
Definition
ChEBI: A phthalate ester that is the dipentyl ester of benzene-1,2-dicarboxylic acid.
Production Methods
Di-n-pentyl phthalate is prepared from n-Amyl alcohol and Phthalic acid (or Phthalic anhydride).
General Description
Clear colorless to light yellow liquid. Practically odorless. Floats on water.
Reactivity Profile
DI-N-AMYL PHTHALATE is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. Can generate electrostatic charges.
Health Hazard
Inhalation of vapors from very hot material may cause headache, drowsiness, and convulsions. Hot vapors may irritate eyes.
Fire Hazard
DI-N-PENTYL PHTHALATE-D4 is combustible.
Chemical Reactivity
Reactivity with Water No reaction; Reactivity with Common Materials: May attack some forms of plastics; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
Safety Profile
Experimental
reproductive effects. When heated to
decomposition it emits acrid smoke and
irritating fumes.
Purification Methods
Wash the ester with aqueous Na2CO3, then distilled water. Dry it with CaCl2 and distil it in a vaccum. Store it in a vacuum desiccator over P2O5. [Beilstein 9 IV 3178.]
