Product Description

Product Description

tert-Butyl Hydroperoxide
tert-Butyl hydroperoxide (TBHP) is an organic peroxide widely used as a reactive intermediate, initiator, and oxidizing agent in various industrial and chemical processes. Below is a detailed introduction:

Basic Information

• Chemical Name: tert-Butyl hydroperoxide
• CAS Number: 75-91-2
• Molecular Formula: C4H10O2
• Molar Mass: 90.12 g/mol
• Appearance: Colorless liquid with a sharp, pungent odor

Physical and Chemical Properties

1. Physical Properties
   • Density: 0.93 g/cm³ (at 20°C)
   • Melting Point: -8°C
   • Boiling Point: 35°C (at 15 mmHg); decomposes before boiling at atmospheric pressure
   • Solubility: Slightly soluble in water (≈1.5 g/100 mL); miscible with organic solvents (e.g., ethanol, acetone, hydrocarbons)
   • Vapor Pressure: 0.3 mmHg (at 20°C)
2. Chemical Properties
   • Thermal Instability:
     • Highly exothermic decomposition above 40°C, releasing CO2, acetone, and other volatile products.
     • Explosive when heated or concentrated, especially in the presence of heavy metal salts (e.g., Fe, Cu, Mn).
   • Oxidizing Ability:
     • Acts as a strong oxidizer, transferring oxygen atoms in reactions (e.g., epoxidation, hydroxylation).
     • Reacts violently with reducing agents, acids, and combustible materials.
   • Radical Initiation:
     • Under heat or light, dissociates to form tert-butoxy radicals ((CH3)3CO⋅) and hydroxyl radicals (⋅OH), making it a common initiator for polymerization reactions (e.g., PVC, polyester resins).

Applications

1. Polymer Industry
   • Polymerization Initiator:
     • Used in free-radical polymerization of vinyl monomers (e.g., styrene, acrylics) and cross-linking of elastomers (e.g., silicone rubber).
     • Provides controlled initiation at moderate temperatures (50-150°C), suitable for bulk, solution, or emulsion polymerization.
   • Curing Agent: In thermoset resins (e.g., unsaturated polyester coatings).
2. Oxidation Reactions
   • Organic Synthesis:
     • Oxidizes alcohols to ketones/aldehydes, sulfides to sulfoxides, and amines to nitro compounds.
     • Used in the production of pharmaceuticals (e.g., oxidation steps in drug synthesis) and agrochemicals.
   • Epoxidation: Converts alkenes to epoxides (e.g., in the production of propylene oxide derivatives).
3. Environmental and Industrial Processes
   • Wastewater Treatment: As a chemical oxidant to degrade organic pollutants (e.g., phenols, cyanides) in advanced oxidation processes (AOPs).
   • Bleaching Agent: In pulp and paper industry for delignification and brightening.
4. Petrochemicals
   • Catalyst Activation: In alkylation, isomerization, and cracking reactions in oil refining.
   • Fuel Additive: Improves combustion efficiency and reduces emissions in diesel fuels (historical use).

Safety and Handling

1. Hazards
   • Explosive Risk: Concentrated solutions (>70%) are highly unstable; shock, heat, or contamination (e.g., metals, acids) can trigger violent decomposition.
   • Toxicity:
     • Skin/eye irritant; causes severe burns on contact.
     • Harmful if inhaled or ingested; may damage the liver and kidneys.
   • Environmental Risk: Toxic to aquatic life; avoid release into waterways.
2. Safety Protocols
   • Personal Protection: Wear chemical-resistant gloves, goggles, and protective clothing.
   • Storage:
     • Store in cool, well-ventilated areas, away from heat, light, and incompatible materials (metals, reducing agents).
     • Use plastic containers (avoid metal) and keep concentrations below 70% in commercial formulations.
   • Handling:
     • Avoid mechanical shock or rapid temperature changes.
     • Dilute solutions before use; never mix with incompatible chemicals.
   • Spill Response: Use absorbent materials (e.g., sand) and neutralize with sodium bicarbonate; avoid water runoff.
