Dibutyl peroxide, tseem hu ua di tert butyl peroxide, pib a, thiab vulcanizing tus neeg sawv cev dTBP, yog cov xim tsis muaj xim rau daj pob tshab kua, insoluble hauv dej, thiab miscible nrog benzene, toluene, acetone thiab lwm yam organic solvents. Nws yog oxidizing heev, flammable, ruaj khov ntawm chav tsev kub, thiab insensitive rau cuam tshuam.
1. Siv raws li 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 (115 degree), thiab 0.15 teev (130. degree), feem. Cov khoom no tuaj yeem tawg thaum nyob rau hauv kev sib cuag lossis nyob rau hauv qhov cuam tshuam ntawm cov neeg ua haujlwm txo qis. Lub teeb nyem yog 18 degree, flammable, thiab nws cov vapor thiab huab cua sib tov los ua ib qho kev sib xyaw tawg. Nws tuaj yeem cuam tshuam rau qhov muag, tawv nqaij, thiab ua pa.
2. Dav siv los ua tus neeg sawv cev crosslinking, monomer polymerization pib, polypropylene modifier, rubber curing agent, thiab lwm yam rau unsaturated polyester thiab silicone roj hmab.
Solubility ntawm Di-tert-butyl peroxide: insoluble hauv dej, soluble hauv ethanol, acetone thiab styrene, thiab miscible nrog benzene thiab roj av. Kev sib cuag ntawm daim tawv nqaij: Tshem tawm thiab cais cov khaub ncaws thiab khau. Tam sim ntawd so txhua yam khoom ntawm daim tawv nqaij. Cia tus neeg mob sov thiab nyob ntsiag to. Xyuas kom cov neeg ua haujlwm kho mob paub txog kev tiv thaiv tus kheej muaj feem xyuam nrog cov khoom siv thiab ua tib zoo saib xyuas lawv tus kheej kev tiv thaiv.
Kev sib cuag qhov muag: Yog tias daim tawv nqaij lossis qhov muag tau ntsib nrog cov khoom, tam sim ntawd yaug nrog dej kom tsawg li 20 feeb.
Inhalation: Txav tus neeg mob mus rau qhov chaw uas muaj huab cua ntshiab. Yog tias tus neeg mob nres ua pa, ua pa ua pa. Yog ua pa nyuaj, muab cov pa oxygen. Cov yam ntxwv ntawm kev pheej hmoo: muaj zog oxidants, yooj yim rau hnov mob nrog ntau lwm yam tshuaj. Peroxides tuaj yeem tsim tsis ruaj khov thiab txaus ntshai peroxides thaum khaws cia. Kev tawg tuaj yeem tshwm sim los ntawm cua sov, kev tsis sib haum xeeb lossis kev sib cuag nrog cov neeg ua haujlwm txo qis, Thiocyanate, organic tshuaj, combustibles los yog kuab paug. Tiv thaiv cov thawv los ntawm kev cuam tshuam, kub siab, thiab tsis sib haum xeeb. Nws tuaj yeem ua rau hluav taws xob zoo li qub los ua kom muaj zog thiab ua kom muaj zog.
1. Ntxiv 222g Tert-Butyl cawv thiab 140g 70 feem pua sulfuric acid rau hauv enamel reverberation kettle, sib tov thiab txias rau 2 ~ -8 degree . Nyob rau hauv kev sib tw khaus, ntxiv 126g ntawm 27 feem pua hydrogen peroxide thiab 400g ntawm cov concentrated sulfuric acid nyob rau hauv 90 feeb, thiab ces do tsis tu ncua rau 3 teev. Cov roj txheej yuav tsum tau muab cais los ntawm sawv ntsug, ntxuav nrog 60ml dej, ntxuav nrog 30 feem pua sodium hydroxide tov kom tshem tawm tert butyl hydrogen peroxide, thiab ntxuav nrog dej. Qhuav cov khoom thiab lim nws los ntawm kev ntxiv magnesium sulfate.
2. Ntxiv 222g (3. mus rau -2 ~ -8 degree nyob rau hauv kev sib tov. Maj mam ntxiv 126g (1.0mol) ntawm 27 feem pua hydrogen peroxide thiab 400g ntawm concentrated sulfuric acid (4.0mol), kwv yees li 1.5g. Tom qab ntxiv, ntxiv sib tov thiab reverberating rau 3 teev. Cais cov roj txheej, ntxuav nws nrog dej, ces ntxuav lub tert butyl hydroperoxide nrog 30 feem pua sodium hydroxide tov, ces ntxuav nws nrog dej, qhuav cov anhydrous magnesium sulfate, lim nws, thiab tau txais Di-tert-butyl peroxide.
