Applications
- TBHP is one of the most commonly used initiators for radical reactions. It is characterized by good thermal stability, safe handling, and ease of control. At...
- , its activity remains stable for three months without significant change, and it does not require costly frozen storage. It can be used in emulsion polymeri...
- outperforms persulfates, isopropylbenzene hydroperoxide, and benzoyl peroxide in many respects. The decomposition products of TBHP are primarily tert-butanol...
- most other initiators form acidic byproducts.
- TBHP is also widely used as a polymerization initiator for styrene, acrylic acid, and methacrylic acid.
- TBHP serves as a vulcanizing agent for natural rubber. It can be used to improve the cetane number of diesel fuel. Additionally, it is a very important organ...
