| Non-Human Toxicity Excerpts | OF 10 RATS DOSED WITH 0.5 ML/KG ... ONE DEATH ... OCCURRED.Diisopropylbenzene occurs in three isomeric forms, namely as the ortho, the meta, and the para derivatives ... . Orally, they are of very low toxicity. Of 10 rats dosed with 5.0 ml/kg, no deaths for the meta, and one death for the ortho and the para isomers occurred. Russian reports of 1970 indicate that rats and rabbits exposed to 0.2 to 1.0 mg/liter (30 to 150 ppm) for 90 minutes daily for 5 weeks developed vascular hyperemia, hemorrhaging in most major organs, and fatty and protein dystrophy in the liver, kidney, and heart, and hyperplasia of the bone marrow. meta-Diisopropylbenzene caused decreased fertility in the rat and mouse at 1 to 3 mg/liter for 30 days.Diisopropylbenzene rated 1 on rabbit eyes /on a scale of 1 to 10 with 10 being the most severe/. /Diisopropylbenzene/ |

Anwendungen & Verwendung
Verwenden
1,4-Diisopropylbenzene is used as an intermediate for the synthesis of stabilizers, polymers, synthetic lubricants and hydroperoxides. It is also used in the trivalent actinide-lanthanide separation by phosphorus reagent extraction from aqueous komplexes (TALSPEAK) process for separating trivalent lanthanides from trivalent actinide cations. It finds application in nuclear fuel reprocessing.
