Organic peroxides yog ib yam khoom organic nrog bivalent OO-structure, thiab tej zaum kuj yog ib tug derivative ntawm hydrogen peroxide. Xws li formic acid (HCOOOH), acetic acid (CH3COOOH), thiab lwm yam. Organic peroxides yog cov khoom uas muaj thermal stability tsis zoo, thiab muaj peev xwm undergo exothermic accelerated decomposition txheej txheem. Lawv cov yam ntxwv ntawm hluav taws kub nyhiab tuaj yeem ua tiav raws li hauv qab no:
Decomposition explosiveness: Organic peroxides tag nrho cov muaj tsis ruaj tsis khov peroxy-OO -, uas yog heev rhiab heev rau tshav kub, kev co, cuam tshuam thiab kev sib txhuam, yog li lawv yuav decompose thaum raug me ntsis sab nraud quab yuam. Yog tias siv diacetyl peroxide, qhov tawg muaj zog tuaj yeem tshwm sim tom qab 24 teev ntawm kev khaws cia tom qab ua tiav cov khoom ntshiab; Thaum cov dej ntsiab lus ntawm benzoyl peroxide qis dua 1 feem pua, kev sib txhuam me ntsis tuaj yeem ua rau tawg; Diisopropyl peroxydicarbonate tsis ruaj khov siab dua 10 degree thiab decomposes thiab tawg thaum nws nce mus txog 17.22 degree; Peracetic acid (peracetic acid) tsis ruaj tsis khov thiab tuaj yeem tawg txawm nyob ntawm -20 degree . Thaum cov concentration ntawm cov tshuaj ntau tshaj 45 feem pua, oxygen tseem tuaj yeem decomposed thaum lub sij hawm cia. Thaum rhuab mus rau 110 degree, nws yuav tawg. Nws tsis yog qhov nyuaj kom pom tias Organic peroxides rhiab heev rau qhov kub thiab txias sab nraud, thiab nws cov kev phom sij thiab kev puas tsuaj ntau dua li lwm cov oxidants.
Flammability: Organic peroxides tsis yog tsuas yog yooj yim rau decompose thiab tawg, tab sis kuj flammable heev, ib co flammable heev. Piv txwv li, lub flash point ntawm Tert-Butyl hydroperoxide yog 26.67 degree. Yog li ntawd, tshwj xeeb yuav tsum tau them rau qhov txaus ntshai ntawm tawg thaum sib ntaus sib tua Organic peroxides hluav taws.
Tsis tas li ntawd, Organic peroxides feem ntau yog ib qho yooj yim rau mob qhov muag, xws li cyclohexanone peroxide, tert butyl hydroperoxide, diacetyl peroxide, thiab lwm yam, uas muaj teeb meem rau qhov muag. Yog li ntawd, tsis txhob pom qhov muag nrog Organic peroxides.
Hauv kev xaus, qhov hluav taws kub ntawm Organic peroxides feem ntau yog nyob ntawm cov ntsiab lus peroxide thiab decomposition kub ntawm cov khoom nws tus kheej. Cov ntsiab lus peroxide ntau dua ntawm Organic peroxides yog, qhov qis dua nws cov thermal decomposition kub yog, thiab qhov ntau dua qhov hluav taws kub.
Nyob rau hauv qeb ntawm cov khoom siv phom sij thiab tawg, muaj peb pawg: cov khoom tawg yooj yim, cov khoom uas ua rau muaj kev kub ntxhov, thiab cov khoom uas tso cov pa taws thaum raug dej. Flammable solids feem ntau yog xa mus rau cov khoom siv uas yooj yim ignited los ntawm ntau yam khoom siv hluav taws xob, cov khoom uas ua rau muaj kev sib txuas nrog huab cua, thiab cov khoom uas tso tawm cov roj hluav taws xob thaum sib cuag nrog dej yog cov khoom tseem ceeb uas tso cov pa taws thiab cua sov thaum nyob rau hauv kev sib cuag nrog dej.
