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
This chemical is combustible.
Description
