CAS 2167-23-9: 2,2-Bis(tert-butylperoxy)butane

Description: 2,2-Bis(tert-butylperoxy)butane, commonly referred to as DTBP, is an organic peroxide characterized by its structure, which includes two tert-butylperoxy groups attached to a butane backbone. This compound is typically a colorless to pale yellow liquid and is known for its strong oxidizing properties. It is primarily used as a radical initiator in polymerization processes, particularly in the production of plastics and synthetic rubber. DTBP decomposes exothermically, releasing oxygen and generating free radicals, which facilitate the initiation of polymer chains. Due to its reactive nature, it must be handled with care, as it can pose risks of combustion and explosion under certain conditions, especially when exposed to heat or contaminants. Additionally, it has a relatively low flash point, making it important to store it in a cool, dry place away from ignition sources. Safety precautions, including the use of personal protective equipment, are essential when working with this substance to mitigate potential hazards associated with its use.
