Diisobutyl Phthalate is a Dialkyl phthalate ester phthalate plasticizer which can be used as a substitute of dibutyl phthalate. Diisobutyl Phthalate as well as other phthalates have genotoxic effects
and studies shown an increase in its monoester metabolite in human urine over the years.
정의
ChEBI: A phthalate ester that is the diester obtained by the formal condensation of the carboxy groups of phthalic acid with two molecules of isobutanol.
생산 방법
Diisobutyl phthalate is manufactured by esterifying phthalic
anhydride and isobutanol in the presence of sulfuric acid.
일반 설명
Oily colorless liquid with a slight ester odor. Denser than water. Insoluble in water. Low toxicity.
공기와 물의 반응
Insoluble in water.
반응 프로필
Diisobutyl phthalate reacts with acids to liberate heat along with isobutyl alcohol and phthalic acid. May react sufficiently exothermically with strong oxidizing acids 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 in handling [Handling Chemicals Safely, 1980. p. 250].
건강위험
Vapors from very hot material may irritate eyes and produce headache, drowsiness, and convulsions.
화재위험
Diisobutyl phthalate is combustible.
Safety Profile
Moderately toxic by
intraperitoneal route. Mdly toxic by
ingestion and skin contact. Experimental
teratogenic and reproductive effects.
Combustible when exposed to heat or
flame. To fight fire, use foam, CO2, dry
chemical. When heated to decomposition it
emits acrid smoke and fumes.
