Decomposition Rate tsis tu ncua
Ntawm qhov kub thiab txias, tus nqi polymerization ntawm monomers feem ntau nyob ntawm tus nqi decomposition Rd ntawm tus neeg pib, uas yog ncaj qha proportional rau thawj lub zog ntawm qhov pib concentration. Ethyl acetate txhawb nqa cov tshuaj tiv thaiv decomposition ntawm persulfate, nrog rau nws tus nqi decomposition tas li nce ntawm 0.248 h⁻¹ mus rau 2.08 h⁻¹ ntawm 80 degree. Methanol kuj tseem muaj feem cuam tshuam rau kev decomposition ntawm persulfate; ntawm methanol concentration ntawm 1 mol / L, tus nqi decomposition nce 25 npaug. Sodium dodecyl sulfate, ib qho emulsifier, kuj tseem txhawb kev decomposition ntawm persulfate.
Active Oxygen ntsiab lus
Cov ntsiab lus oxygen nquag, tseem hu ua cov ntsiab lus oxygen zoo, sawv cev rau tus naj npawb ntawm cov dawb radicals tsim tom qab decomposition ntawm qee qhov loj ntawm peroxide.
Qhov ntsuas kub tseem ceeb
Qhov no yog hais txog qhov ntsuas kub qis tshaj plaws uas cov peroxide decomposes los tsim cov dawb radicals. Qhov ntsuas kub tseem ceeb txawv me ntsis ntawm qhov decomposition kub, uas yog qhov kub ntawm ib nrab - lub neej ntawm peroxide yog 10 h (los yog 1 min). Qhov ntsuas kub tseem ceeb ntawm peroxides siv los ua cov pib yog feem ntau ntawm 60 thiab 130 degree. Yog tias qhov ntsuas kub qis dua 60 degree, chav tsev kub tsis ruaj khov, ua rau lawv tsis tsim nyog raws li cov neeg pib. Ib nrab-lub neej: Ib nrab-lub neej yog hais txog lub sijhawm xav tau rau tus neeg pib ua kom tawg mus rau ib nrab ntawm nws qhov pib concentration ntawm qhov kub thiab txias. Nws yog siv los ntsuas qhov kev ua ntawm tus pib lossis tus nqi tshuaj tiv thaiv. Piv txwv li, ntawm 60℃, qhov decomposition kub ntawm ib tug pib nrog ib nrab - lub neej ntawm 10 teev nyob rau hauv ib tug hnyav (benzene los yog toluene) feem ntau hu ua decomposition kub ntawm tus pib.
Ua kom muaj zog
Lub zog ua kom muaj zog (Ed) yog qhov tseem ceeb hauv kev txiav txim siab tus nqi decomposition ntawm tus neeg pib thiab tuaj yeem tau txais los ntawm Arrhenius empirical formula. Lub zog ua kom siab dua txhais tau hais tias tus neeg pib ua haujlwm tsis tshua muaj kev puas tsuaj tab sis ruaj khov dua; Lub zog ua kom qis dua txhais tau tias nws decomposes yooj yim dua, tsim cov dawb radicals.
Tus nqi decomposition tas mus li, ib nrab -lub neej, thiab decomposition ua kom lub zog ntawm tus neeg pib tuaj yeem ua lub hauv paus rau kev xaiv cov pib, qhov kub thiab txias polymerization, thiab cov voj voog ntau lawm.
