Applications:

Plasperox TBH - 80's thermal stability provides for safer handling than other commonly used oxidizing agents. It has a high self-accelerating decomposition temperature (190°F/88°C). Little to no decomposition occurs up to moderate temperatures (~100°F/38°C). As a result, storage and handling do not present the difficulties associated with many other organic peroxides.

Plasperox TBH - 80 provides versatility and convenience in many applications because of solvent compatibility. Plasperox TBH - 80's solubility in water is about 15 wt.%. Plasperox TBH - 80 is also miscible with most organic solvents.

Plasperox TBH - 80 provides excellent reactivity control with appropriate catalyst choice and often mild reaction conditions. Selectivity advantages include regioselectivity, stereoselectivity, and chemoselectivity. When reacted, the byproduct tertiary butyl alcohol is stable. Simple distillation easily reduces the alcohol to low residual levels.

Plasperox TBH - 80 is also more cost effective than competitive organic peroxides due to its low price and high efficiency.

HANDLING & STORAGE :

Storage is recommended at less than 200 C. If frozen allow to thaw at room temperature. Never apply heat. Plasperox TBH - 80 is a yellow label material. Handle with caution. Keep it away from all sources of Ignition (Heat, Spark, Flames). Avoid contamination with accelerator and metals. The biotreatability of aqueous TBHP streams has not been identified. Reducing agents as well as acids and transition metals ions which may be available in waste water streams can convert TBHP to tertiary butyl alcohol. No data exists at this time estimating the percent conversion in a typical waste water stream. Studies indicate that tertiary butyl alcohol is treatable in acclimated, well-operated biological treatment systems. However, the conditions and/or retention time required may exceed typical conditions. The primary pathways for TBHP removal from soils probably are biodegradation and transport to groundwater. Available information indicates that Plasperox TBH - 80 should not bioaccumulate in plants and animals.
