Description

Ditertiary butyl peroxide is a clear, water-white liquid. It has a specific gravity of 0.79, which is lighter than water, and it will float on the surface. It is nonpolar and insoluble in water. Ditertiary butyl peroxide is a strong oxidizer and may ignite organic materials or explode if shocked or in contact with reducing agents. In addition to being an oxidizer, ditertiary butyl peroxide is highly flammable. It has a boiling point of 231°F (110°C) and a flash point of 65°F (18°C). The NFPA 704 designation is health 3, flammability 2, and reactivity 4. The prefix “oxy” for oxidizer is placed in the white section at the bottom of the 704 diamond.

Features of Rutile Titanium Dioxide

*Better anti-pulverization ability and gloss retention.

*The hygroscopicity is less than antase type.

*Its dielectric constant and semiconductor properties are very important to the electronics industry, which can be used to produce electronic components for ceramic capacitors.

*High refractive index, hiding power and gloss are better than anatase TiO2.

*The structure is more compact and stable, and the photochemical activity is small, so the weather resistance is much better.

Reactivity Profile

The explosive instability of the lower dialkyl peroxides (e.g., dimethyl peroxide) and 1,1-bis-peroxides decreases rapidly with increasing chain length and degree of branching, the di-tert-alkyl derivatives being amongst the most stable class of peroxides. Though many 1,1-bis-peroxides have been reported, few have been purified because of the higher explosion hazards compared with the monofunctional peroxides. Di-tert-butyl peroxide is unlikely that this derivative would be particularly unstable compared to other peroxides in it's class, Bretherick 1979v.

Health Hazard

DTBP is slightly toxic by inhalation andin general exhibits low to very low toxicityby other routes. However, toxic effectsare observed only at very high concentrations.Rats exposed to 4103-ppm vapor developedhead and neck tremor after 10 minutesof exposure (Floyd and Stockinger 1958).Other symptoms were weakness, hyperactivity,and labored breathing. However, theanimals recovered fully in 1 hour.

LD50 value, intraperitoneal rats): 3210 mg/kg

DTBP is nonirritating to the skin and mildon the eyes. It is reported to cause lungand blood tumors in mice (NIOSH 1986).However, its carcinogenicity is not yet fullyestablished.

Fire Hazard

Highly flammable and reactive; flash point 18°C (64.4°F); vapor pressure 19.5 torr at 20°C (68°F); vapor density 5.03. Its decomposition products are ethane and acetone, which enhance the fire hazard. Use a water spray to fight fire and to keep the containers cool.

DTBP forms an explosive mixture with air. The explosive range is not reported. Its decomposition products may explode above its boiling point, 111°C (231.8°F). However, as it is thermally stable and shock insensitive, its explosion hazard is much lower. It may, however, react with explosive violence when in contact with easily oxidizable substances.
