Üsivesinikke
Üsivesinikke, also known as organic peroxides, are a class of compounds characterized by the presence of a peroxide functional group (-O-O-). This group consists of two oxygen atoms covalently bonded to each other. The general formula for organic peroxides is R-O-O-R', where R and R' are alkyl or aryl groups, or hydrogen atoms. Due to the relatively weak oxygen-oxygen bond, organic peroxides are often unstable and can decompose readily, releasing oxygen radicals. This property makes them useful as initiators in polymerization reactions, such as the production of plastics like polyethylene and PVC. They also find applications as curing agents for resins and in some bleaching processes. However, their instability also makes them hazardous materials, as they can be sensitive to heat, shock, and friction, potentially leading to explosive decomposition. Proper handling, storage, and transportation procedures are therefore crucial when dealing with üsivesinikke. They are classified as dangerous goods and require specific safety precautions. The reactivity of üsivesinikke can be modified by the nature of the R and R' groups attached to the peroxide linkage, influencing their stability and decomposition temperature.
