Lub ntsiab siv ntawm metyl acetate yog feeb los nyob rau hauv cov teb ntawm cov txheej txheem kev siv tshuaj txhuam thiab cov tshuaj tsw qab thiab cov tshuaj tsw qab. Nws yog dav siv nyob rau hauv ntau daim teb kev lag luam vim nws cov kev tiv thaiv kev tiv thaiv tsawg thiab ib puag ncig kev tiv thaiv ib puag ncig. Cov kev siv tshwj xeeb thiab cov xwm txheej muaj raws li hauv qab no:
1. Cov Ntawv Thov
} -}} qhuav cov kuab tshuaj
Nws yog siv los yaj cov ntaub ntawv xws li Nitrocellulose, cov cellulose acetatate, resins, inks, pleev xim, thiab muaj cov yam ntxwv ntawm kev loj ceev.
Nws hloov cov kuab tshuaj yeeb yaj kiab xws li acetone, Butanone, thiab kev tawm tsam kev tiv thaiv vim yog kev tiv thaiv ib puag ncig thiab ib puag ncig, uas muaj ntau dua nyob rau hauv cov qauv kev lag luam niaj hnub no.
2. Tshuaj Lom Cov Khoom Siv Raw
Synthesis ntawm Lwm Yam Tshuaj
Nws tsim cov khoom siv tshuaj xws li acetic acid, acetic anhydride, Methyl acrylate, yas acetate thiab acetamide. Ntawm lawv, tus kab mob carbonyhlation txoj kev rau kev ua cov acetic anhydride yog tam sim no yog kev lag luam txheej txheem tshaj plaws.
Raws li cov khoom siv hluavtaws rau cov neeg ua noj ua haus, tshuaj thiab cov chaw muag tshuaj muaj zog, nws yog siv nyob rau hauv cov chaw ua haujlwm thiab zoo.
3. Tshuaj lom neeg thiab kev lag luam khoom noj khoom haus
Cov tshuaj tsw qab thiab cov khoom noj ntxiv
Nws yog siv nyob rau hauv synthesis ntawm cov ntxhiab tsw qab (xws li cov txiv hmab txiv ntoo qab zib) thiab muaj npe raws li kev tso cai tshuaj tsw qab nyob rau hauv lub teb chaws tus qauv (GB 2760-1996) ntxiv cov tsw rau khoom noj.
Nws yog siv los ua qhov qis - kev siv tshuaj lom rau cov khoom lag luam chemical xws li ntsia thawv ntsia hlau pishing thiab kua nplaum.
4. Lwm cov ntawv thov muaj
Foaming Tus Neeg Sawv Cev thiab Extraction Tus Neeg Sawv Cev
Nws yog siv los ua ib puag ncig tus neeg sawv cev ua npuas ncauj hloov mus los hloov cyclotomentane, chlorofluorocarbons, thiab lwm yam nyob rau hauv kev tsim cov polyurethane khau cov ntaub ntawv.
Nws yog siv rau cov roj extraction, tawv ua thiab tsim tawv tsim.
Kev tshawb fawb sim
Nws yog siv los ua cov qauv txheem thiab cov kuab tshuaj rau chromatographic tsom xam, lossis rau cais lithium chloride los ntawm alkali hlau chlorides.
Cov ntsiab lus: Methyl acetate lawb txoj hauj lwm tseem ceeb hauv kev ua yeeb yam, cov khoom noj khoom haus yeeb tshuaj, thiab lwm yam. Vim nws cov tshuaj lom neeg muaj zog thiab kev tiv thaiv ib puag ncig. Hauv kev lag luam niaj hnub, nws txoj kev hloov pauv cov kev coj noj coj ua kom muaj qhov tseem ceeb tshaj, ntxiv txhawb kev tsim khoom ntsuab.
