Chemische Eigenschaften
colourless to light yellow liquid
Verwenden
Initiates degradation of polypropylene, monomer scavenger in styrene polymerization. Free radical polymerization initiator.
Application
2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane is an efficient peroxide for the degradation of polypropylene (CR-PP) in the temperature range of 200-250°C. It can also be used as chaser catalyst to reduce residual monomer in the mass polymerization of styrene. It is used for the crosslinking of natural and synthetic rubber, as well as thermoplastic polyolefins: Rubber compounds containing Trigonox 101 have excellent scorch safety. Safe processing temperature: 135°C(rheometer t_s2 > 20 minutes). Typical crosslinking temperature: 175 ℃ (rheometer t₉₀ about 12 minutes).
Allgemeine Beschreibung
2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane, also known as trigonox 101, is a clear, yellow liquid. (NTP, 1992)also for storage and transport mixed with inert solid.
Air & Water Reaktionen
Insoluble in water.
Reaktivität anzeigen
Peroxides, such as 2,5-DIMETHYL-2,5-DI-(TERT-BUTYLPEROXY)HEXANE, are good oxidizing agents. Organic compounds can ignite on contact with concentrated peroxides. Strongly reduced material such as sulfides, nitrides, and hydrides may react explosively with peroxides. There are few chemical classes that do not at least produce heat when mixed with peroxides. Many produce explosions or generate gases (toxic and nontoxic). Generally, dilute solutions of peroxides (<70%) are safe, but the presence of a catalyst (often a transition metal such as cobalt, iron, manganese, nickel, or vanadium) as an impurity may even then cause rapid decomposition, a buildup of heat, and even an explosion. Solutions of peroxides often become explosive when evaporated to dryness or near-dryness. Danger of explosion when dry. May explode from heat, shock, friction or contamination. May ignite combustibles (wood, paper, oil, clothing, etc.). May be ignited by heat, sparks or flames.
Flammability and Explosibility
Flammable
Sicherheitsprofil
Moderately toxic by intraperitoneal route. Combustible when exposed to heat, flames, or reducing agents. To fight fire, use water spray, foam, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes. Used in the polymerization of styrene and in cross-linking of various grades of polyethylene. See also PEROXIDES, ORGANIC.
mögliche Exposition
It is used as a catalyst in making polyethylene, polystyrene, and polyester resins.
Erste Hilfe
If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit.
Lager
Color Code—Yellow Stripe: Reactivity Hazard;Store separately in an area isolated from flammables, combustibles, or other yellow-coded materials. Prior to workingwith this chemical you should be trained on its proper handling and storage. Store in tightly closed containers in acool, well-ventilated area away from strong oxidizers (suchas chlorine, bromine, and fluorine), strong acids (such ashydrochloric, sulfuric, and nitric), and combustibles.Sources of ignition, such as smoking and open flames, areprohibited where 2,5-dimethyl-2,5-di(tert-butyl peroxy)hexane is used, handled, or stored in a manner that could createa potential fire or explosion hazard. Use only nonsparkingtools and equipment, especially when opening and closingcontainers of 2,5-dimethyl-2,5-di(tert-butyl peroxy)hexane.See OSHA Standard 1910.104 and NFPA 43A Code for theStorage of Liquid and Solid Oxidizers for detailed handlingand storage regulations.
Versand/Shipping
This compound requires a shipping label of“ORGANIC PEROXIDE.” It falls in Hazard Class 5.2 andPacking Group II.
Inkompatibilitäten
Unstable organic peroxide. Strong oxidizer; potentially explosive. Forms explosive mixture withair. Reacts with reducing agents, strong oxidizers, strongacids, combustible materials.
