Diundecyl Phthalate is a phthalate diester and has been investigated for its toxicology in male rats for risk assessment.
DUP is manufactured by the reaction of phthalic anhydride
with undecanol in the presence of an acid catalyst.
Oily colorless odorless liquid. Less dense than water.
Diundecyl phthalate reacts 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 interaction with caustic solutions. Flammable hydrogen is generated by mixing with alkali metals and hydrides. Can generate electrostatic charges [Handling Chemicals Safely, 1980. p. 250].
Produces no ill effects at normal temperatures but may give off irritating vapor at high temperature.
Diundecyl phthalate is probably combustible.
