Half-life yog dab tsi?
** Ib nrab-lub neej ** hais txog lub sijhawm nws siv rau cov organic peroxide kom decompose mus rau ib nrab ntawm nws cov nqi qub ntawm qhov kub thiab txias. Zoo li nuclear lwj, organic peroxides decompose maj mam ntawm txhua qhov kub, tab sis qhov kub thiab txias, qhov decomposition sai dua. Rau TBPB (Tert-Butyl Peroxybenzoate), cov ntaub ntawv paub yog:
- Ntawm 167 degree, ib nrab-lub neej yog 1 feeb.
- Ntawm 125 degree, ib nrab-lub neej yog 1 teev.
- Ntawm 103 degree, ib nrab-lub neej yog 10 teev.
Cov ntaub ntawv no qhia tau hais tias txawm tias qhov kub tsis ncav cuag SADT, qhov me me ntawm decomposition yuav tshwm sim ntawm qhov kub siab dua. Txij li qhov decomposition no yog exothermic cov tshuaj tiv thaiv, qhov chaw cia khoom tsis raug (xws li qhov kub thiab txias ib puag ncig lossis kev cia ntev ntev) yuav maj mam ua rau muaj qhov xwm txheej txaus ntshai txawm tias qhov pib kub tsis tshaj SADT.https://www.kz-opchem.com/organic-peroxides/tertial-butyl-peroxybenzoate.html
