colourless liquid | [General Description]
2,4,4-Trimethyl-1-pentene is a α-alkene. It is the main dimeric product of isobutene. Ozonolysis of 2,4,4-trimethyl-1-pentene has been investigated in a flow reactor under pseudo-first-order conditions. Hydrocracking (HCG) of 2,4,4-trimethyl-1-pentene has been employed as a model test reaction to investigate the catalytic functionalities of sulfided CoMo catalysts. Liquid phase oxidation of 2,4,4-trimethyl-1-pentene with molecular xygen afforded epoxides and hydrogen peroxides. | [Hazard]
Flammable, dangerous fire risk. | [Health Hazard]
Recommended Personal Protective Equipment: Protective goggles; Symptoms Following Exposure: Low general toxicity; may act as simple asphyxiate in high vapor concentrations; General Treatment for Exposure: INHALATION: remove from exposure; support respiration; Toxicity by Inhalation (Threshold Limit Value): Data not available; Short-Term Exposure Limits: Data not available; Toxicity by Ingestion: Data not available; Late Toxicity: Liver and kidney damage in exp. animals; Vapor (Gas) Irritant Characteristics: Vapors are nonirritating to the eyes and throat; Liquid or Solid Irritant Characteristics: Minimum hazard. If spilled on clothing and allowed to remain, may cause smarting and reddening of the skin; Odor Threshold: Data not available. | [Chemical Reactivity]
Reactivity with Water No reaction; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent. | [Toxics Screening Level]
Due to a lack of available toxicity information the ITSL is being set at 0.1 μg/m3 with annual averaging. |
