Tau kawg! peb tshwj xeeb hauv kab no tau ntau xyoo, ntau tus neeg siv khoom ua ib daim ntawv cog lus nrog kuv vim peb tuaj yeem xa cov khoom raws sijhawm thiab khaws cov khoom zoo tshaj plaws!

Kuv puas tuaj yeem mus xyuas koj lub tuam txhab thiab lub Hoobkas hauv Suav teb?

Tseeb. Koj zoo siab tos txais koj tuaj xyuas peb lub tuam txhab hauv Zibo, Suav teb. (1.5H tsav tsheb los ntawm Jinan)

Kuv tuaj yeem tso qhov kev txiav txim li cas?

Koj tuaj yeem xa peb cov lus nug rau peb cov neeg sawv cev muag khoom kom tau txais cov ntaub ntawv qhia txog kev txiav txim, thiab peb yuav piav qhia txog cov txheej txheem kom ntxaws. Kev Tsim Khoom Siv Tshuab ntawm Maleic Anhydride
Maleic anhydride yog ib yam tshuaj lom neeg tseem ceeb heev, siv dav hauv kev lag luam xws li plastics, dyes, thiab pharmaceuticals. Hauv qab no, peb qhia txog cov txheej txheem tsim khoom ntawm maleic anhydride.
Muaj plaub txoj kev tsim khoom rau maleic anhydride: txoj kev phenoxypropanol, txoj kev ethylene dehydrogenation, txoj kev phthalic anhydride, thiab txoj kev tshuaj lom neeg thee.
Ua ntej yog txoj kev phenoxypropanol: Cov txheej txheem no suav nrog kev sib xyaw benzene nrog benzyl oxide los tsim cov phenoxypropanol, uas tom qab ntawd oxidized nrog huab cua los tsim cov maleic anhydride. Nws cov txiaj ntsig suav nrog qhov kub tsawg ntawm cov tshuaj tiv thaiv, cov tshuaj reactants yooj yim nkag mus, thiab cov zis siab.
Tom ntej no yog txoj kev ethylene dehydrogenation: Hauv cov txheej txheem no, ethylene yog dehydrogenated nyob rau hauv lub catalysis ntawm tartaric acid los tsim acrolein; lub acrolein ces raug rau denitrification thiab deoxygenation kom tau txais maleic anhydride. Cov txiaj ntsig ntawm txoj kev no yog cov xwm txheej tsis tshua muaj zog thiab muaj peev xwm siv ethylene ncaj qha ua cov khoom siv raw.
Txoj kev thib peb yog txoj kev phthalic anhydride: Ntawm no, phthalic anhydride yog siv ua cov khoom siv raw, thiab maleic anhydride yog tsim los ntawm kev ua pa oxygen thiab decarboxylation. Cov txheej txheem no yog tus cwj pwm los ntawm cov khoom siv raw yooj yim thiab cov txheej txheem tsim khoom yooj yim.
Thaum kawg, txoj kev siv tshuaj lom neeg ntawm cov thee: Txoj hauv kev no siv cov thee ua cov khoom siv raw, uas yog pyrolyzed ntawm qhov kub siab los tsim cov roj; tom qab ntawd cov tshuaj oxidation thiab decarboxylation ces ua rau muaj maleic anhydride. Nws qhov txiaj ntsig tseem ceeb yog tias cov thee yog cov peev txheej muaj ntau, ua rau siv tau zoo ntawm cov khoom siv thee.
