Methyl methacrylate (MMA) ingagwiritsidwe ntchito m'njira zosiyanasiyana:

Ntchito yaikulu: Monga monomer ya galasi lachilengedwe (polymethylmethacrylate, PMMA), yomwe imagwiritsidwa ntchito popanga mapulasitiki owonekera.
Mapulasitiki ena ndi zokutira: Amagwiritsidwa ntchito popanga ma resin ena, mapulasitiki, ndi zokutira, zomwe zimapereka zinthu zofunika kwambiri m'mafakitale awa.
Ntchito zambiri zamafakitale: Monga mafuta odzola, matabwa ndi kukula kwa cork, chonyowetsa coil ya mota, chopukutira mapepala, chosindikizira ndi chopaka utoto cha nsalu, chothandizira pakuchiza chikopa ndi zinthu zodzaza ndi insulation, ndi zina zotero, chimagwiritsidwa ntchito kwambiri m'mafakitale ambiri.
Fungicide wapakati: Monga wapakati pa Sclerotium ya fungicide, imagwiritsidwa ntchito popanga mankhwala ophera tizilombo.
Methyl methacrylate ndi chinthu chofunikira kwambiri chopangira mankhwala. Nthunzi yake ndi mpweya wake zimatha kupanga chisakanizo chophulika. Chonde samalani za chitetezo mukachigwiritsa ntchito4. Sikuti imangokhala ndi gawo lofunikira kwambiri mumakampani opanga mapulasitiki ndi zokutira, komanso imagwiranso ntchito m'magawo ena ambiri.

Njira iliyonse ili ndi makhalidwe akeake, ndipo njira zoyenera zopangira zitha kusankhidwa malinga ndi zosowa ndi mikhalidwe inayake.

Njira zopangira methyl methacrylate (MMA) makamaka zimaphatikizapo izi:

Njira ya Acetone cyanohydrin: Gwiritsani ntchito acetone ngati zinthu zopangira, choyamba yambitsani ndi hydrocyanic acid kuti mupange acetone cyanohydrin, kenako itentheni ndi sulfuric acid yokhazikika ndi methanol kuti mupange hydrolysis, kusowa madzi m'thupi komanso esterification reactions kuti mukonzekere MMA. Njirayi ndi njira yodziwika bwino yopangira MMA. Ukadaulowu ndi wokhwima, koma hydrocyanic acid ya zinthu zopangira ndi poizoni kwambiri ndipo zinyalala zitatuzi ndi zovuta kuzikonza.
Njira ya Isobutylene: Isobutylene imasinthidwa kukhala methacrolein ndi mpweya pamaso pa chothandizira, kenako imasinthidwa kukhala methacrylic acid, ndipo pamapeto pake imasinthidwa ndi methanol kuti ipange MMA. Palinso njira imodzi yokha yosungunuka yomwe imasungunuka mwachindunji kuti ipange methacrylic acid kenako n’kuiyeretsa.
Njira ya Propylene: Kachitidwe ka carbonylation ka propylene, carbon monoxide ndi methanol kamapanga 2-methoxyisobutyric acid methyl ester, yomwe imasungunuka kukhala MMA ndi methanol pambuyo pa hydrolysis.
