2-tert-butylphenol Soluble hauv ethanol thiab ether. Cov txheeb ze ntom ntom (d204) 0.9783. melting point -7 ℃. Kub taw tes 221 ~ 224 ℃. Refractive index (n20D) 1.5228. Flash point 110 ℃. Irritating rau qhov muag, ua pa system thiab tawv nqaij.
Nws yog tsuas yog siv los ua antioxidant, nroj tsuag tiv thaiv tus neeg sawv cev, hluavtaws cob, tshuaj, tshuaj tua kab nruab nrab thiab raw khoom ntawm tsw thiab tshuaj tsw qab.
p-tert-butylcatechol yog ib qho tseem ceeb ntawm cov khoom siv tshuaj zoo nrog ntau yam kev siv. Nws cov synthesis feem ntau yog raws li txoj kev alkylation ntawm catechol. Raws li kev tshawb fawb cov ntaub ntawv, alkylation txoj kev rau cov synthesis ntawm p-tert-butylcatechol muaj lub sij hawm ntev cov tshuaj tiv thaiv, siab zog thov, loj corrosion ntawm cov khoom, thiab ib puag ncig muaj kuab paug los ntawm cov khoom sib cais txheej txheem. Cov yam ntxwv no tsis ua tau raws li qhov yuav tsum tau muaj ntawm kev tsim khoom thiab tshuaj ntsuab ntsuab. Lub hydroxylation ntawm phenols nrog hydrogen peroxide muaj cov tshuaj tiv thaiv me me, cov khoom siv yooj yim thiab pheej yig, thiab kev ua siab zoo ib puag ncig, uas ua tau raws li cov kev cai ntawm ntsuab chemistry. Ntawm lawv, cov txheej txheem hydroxylation ntawm phenol tau muaj kev lag luam, thiab kev kawm theoretical ntawm benzene hydroxylation cov tshuaj tiv thaiv kuj tseem paub tab. Txawm li cas los xij, qhov ncaj qha hydroxylation ntawm p-tert-butylphenol nrog hydrogen peroxide los npaj p-tert-butylcatechol tau raug tshaj tawm tsis tshua muaj.
Chemwin tuaj yeem muab ntau hom hydrocarbons thiab cov kuab tshuaj tshuaj lom neeg rau cov neeg siv khoom.Ua ntej ntawd, thov nyeem cov lus qhia hauv qab no txog kev ua lag luam nrog peb:
1. Kev ruaj ntseg
Kev nyab xeeb yog peb qhov tseem ceeb tshaj plaws. Ntxiv nrog rau kev muab cov neeg siv khoom paub txog kev nyab xeeb thiab ib puag ncig tus phooj ywg siv peb cov khoom, peb kuj tau cog lus los xyuas kom meej tias kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov neeg cog lus raug txo qis rau qhov tsim nyog thiab ua tau yam tsawg kawg nkaus. Yog li, peb xav kom tus neeg siv khoom kom ntseeg tau tias qhov tsim nyog tshem tawm thiab khaws cov qauv kev nyab xeeb tau ua tiav ua ntej peb xa khoom (thov xa mus rau HSSE appendix nyob rau hauv cov nqe lus dav dav thiab kev muag khoom hauv qab no). Peb cov kws tshaj lij HSSE tuaj yeem muab kev taw qhia txog cov qauv no.
2. Txoj kev xa khoom
Cov neeg siv khoom tuaj yeem xaj thiab xa cov khoom los ntawm chemwin, lossis lawv tuaj yeem tau txais cov khoom los ntawm peb cov chaw tsim khoom. Cov hom kev thauj mus los muaj xws li tsheb thauj mus los, tsheb ciav hlau lossis kev thauj mus los ntau yam (xws li kev sib cais).
Nyob rau hauv cov ntaub ntawv ntawm cov neeg yuav tsum tau, peb muaj peev xwm qhia kom meej qhov yuav tsum tau ntawm barges los yog tankers thiab siv tshwj xeeb kev nyab xeeb / tshuaj xyuas cov qauv thiab cov kev cai.
3. Yam tsawg kawg nkaus kom muaj nuj nqis
Yog tias koj yuav khoom los ntawm peb lub vev xaib, qhov kev txiav txim yam tsawg kawg nkaus yog 30 tons.
4. Kev them nyiaj
Txoj kev them nyiaj tus qauv yog txiav tawm ncaj qha hauv 30 hnub txij li daim ntawv xa nyiaj.
5. Cov ntaub ntawv xa tuaj
Cov ntaub ntawv hauv qab no tau muab nrog rau txhua qhov kev xa khoom:
· Bill of Lading, CMR Waybill lossis lwm yam ntaub ntawv thauj mus los
· Certificate of Analysis los yog Conformity (yog xav tau)
· Cov ntaub ntawv hais txog HSSE raws li txoj cai
· Cov ntaub ntawv kev lis kev cai raws li txoj cai (yog tias xav tau)
