Hydroperoxides
Trigonox
Our Trigonox® range of hydroperoxides includes isopropylcumyl hydroperoxide, cumyl hydroperoxide, tert-butyl hydroperoxide, tert-amyl hydroperoxide and 1,1,3,3-tetramethylbutyl hydroperoxide.
Structure
Hydroperoxides have the general structure RO-OH wherein R represents alkyl and/or aryl groups. Upon cleavage of the peroxide bond free radicals, RO· and ·OH, are formed.
Applications
Hydroperoxides are mainly used in the production of low density polyethylene (LDPE), acrylics, styrenics and other thermoplastics. Cumy hydroperoxide is also used in thermoset applications such as continuous lamination.
Half-life
Hydroperoxides are the most thermally stable class of organic peroxides. Their 1 hour half-life temperature lies in the range of 125-190 °C. The half-life is the most important characteristic of a polymerization initiator. It is the time required to reduce the original amount of an organic peroxide at a given temperature by 50%. Kinetic data of hydroperoxides in monochlorobenzene are determined titrimetrically.
Half-life temperatures of our hydroperoxides can be found in the AkzoNobel product catalog "Initiators and Reactor Additives for Thermoplastics" which can be downloaded from this page.
