Peroxides tseem hu ua cov thawj coj lossis cov tshuaj ntxiv. Niaj hnub no peb qhia txog kev siv thiab kev sib txuas ntawm Di-tert-butyl peroxide, vam tias yuav coj kev pab ntxiv rau peb cov phooj ywg!
Txheej txheem cej luam: Di-tert-butyl peroxide belongs rau Organic peroxides, uas yuav siv tau raws li crosslinking tus neeg saib xyuas ntawm unsaturated polyester thiab silicone roj hmab, thiab kuj raws li polymerization pib.
Cov Khoom Siv: Cov txheej txheem tsim khoom ntawm DTBP (initiator A) tsis tu ncua, thiab cov dej zoo, cov organic teeb meem concentration, pH, ntsev cov ntsiab lus, BOD / CDO tus nqi ntawm cov dej khib nyiab sib txawv heev nrog cov khoom tsim thiab lub sijhawm. DTBP yog thermally tsis ruaj khov thiab nquag ua kom nrawm nrawm, ua rau tawg; Lub DTBP yaj nyob rau hauv Chemicalbook nyob rau hauv cov dej khib nyiab kuj sai decomposes ntawm kub kub, ua rau muaj kev nyab xeeb. Cov txheej txheem tsim khoom tsim tawm ntau cov kua qaub pov tseg, thiab ntau cov alkaline ntxuav cov kua khib nyiab yog tsim thaum lub sij hawm ua kom huv. Qhov concentration ntawm cov pa phem hauv cov dej khib nyiab yog siab, muaj pes tsawg leeg yog complex, thiab B / C tus nqi qis heev, ua rau nws tsis yooj yim rau kev kho biochemical. Kev tso tawm ncaj qha ntawm hom dej khib nyiab no rau hauv cov dej ntws tuaj yeem ua rau dej paug loj.
Daim Ntawv Thov: DTBP (initiator A) yog ib qho ruaj khov thiab feem ntau siv Organic peroxides pib. Raws li tus neeg sawv cev crosslinking, nws tuaj yeem siv rau hauv cov roj hmab silicone, hluavtaws roj hmab thiab cov roj hmab ntuj, polyethylene chemicalbook, EVA, thiab EPT, thiab lwm yam. Raws li lub polymerization pib, nws tuaj yeem siv rau polystyrene thiab polyethylene. Nws kuj tseem siv tau los ua cov tshuaj pleev xim rau cov roj thiab cov khoom noj, ib qho ntxiv rau cov roj diesel thiab cov roj lubricating, thiab lub ncuav qab zib depressant rau transformers.
Chemical Properties: Colorless kua. Melting point {{0}} degree, boiling point 111 degree, 80 degree (37.8kPa), 70 degree (26.2kPa), txheeb ze Chemicalbook ceev (20/4 degree) 0.794, refractive index 1.3890. Nws yog miscible nrog benzene, Petroleum ether thiab lwm yam organic solvents. Insoluble hauv dej. Nws muaj zog oxidizing zog.
Kev Siv: Siv los ua tus neeg sawv cev crosslinking rau unsaturated polyester thiab silicone roj hmab, thiab kuj yog ib tug polymerization pib. Lub theoretical nquag oxygen cov ntsiab lus yog 10.94 feem pua, lub zog ua haujlwm yog 146.9 kJ / mol, thiab ib nrab lub neej yog 218 teev (100 degree), 34 teev Tshuaj (115 degree), thiab 0.15 teev ( 130 degree). Cov khoom no yuav tawg nyob rau hauv kev sib cuag nrog txo cov neeg ua hauj lwm los yog nyob rau hauv kev cuam tshuam. Lub teeb nyem yog 18 degree, flammable, thiab nws cov vapor sib xyaw nrog huab cua los tsim cov khoom tawg. tuaj yeem ua rau lub qhov muag, tawv nqaij, thiab ua pa. Dav siv los ua tus neeg sawv cev crosslinking rau unsaturated polyester thiab silicone roj hmab, polymerization pib rau monomers, polypropylene modifier, roj hmab vulcanizing tus neeg saib xyuas, thiab lwm yam
Txoj kev tsim khoom: Tert-Butyl cawv reacts nrog hydrogen peroxide nyob rau hauv concentrated sulfuric acid. Sib tov thiab txias 222g (3mol) Tert-Butyl cawv thiab 140g (1mol) 70 feem pua sulfuric acid rau -2 - -8 degree . Nyob rau hauv kev sib tw khaus, ntxiv 126g (1Chemicalbookmol) ntawm 27% hydrogen peroxide thiab 400g (4mol) ntawm cov concentrated sulfuric acid dropwise hauv 90 feeb. Tom qab ntxiv, ntxiv stirring rau 3 teev. Cais cov roj txheej, ntxuav nws nrog 60ml dej, ces ntxuav nws nrog 30 feem pua sodium hydroxide tov kom tshem tawm tert butyl hydroperoxide, thiab thaum kawg ntxuav nws nrog dej thiab qhuav nrog magnesium sulfate kom tau cov khoom tiav.
