Maleic anhydride ali ndi mawonekedwe okhazikika komanso magwiridwe antchito abwino kwambiri pakupanga utomoni. Zimagwira ntchito yofunika kwambiri popanga utomoni wosiyanasiyana monga unsaturated polyester resins, alkyd resins, ndi ma phenolic resins osinthidwa. Maleic anhydride's reactivity yabwino kwambiri komanso kuyanjana ndi mitundu yosiyanasiyana ya ma polima kumawonjezera mawotchi komanso kutentha kwa utomoni, ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito mosiyanasiyana.

Chimodzi mwazinthu zazikulu za maleic anhydride ndi kusungunuka kwake m'madzi, komwe kumatha kupanga maleic acid akasungunuka m'madzi. Izi zimapangitsa kuti zikhale zosavuta kuzigwiritsa ntchito ndikuziphatikiza m'madzi opangira madzi, ndikuwonjezeranso ntchito yake popanga utomoni wamadzi. Kuphatikiza apo, anhydride ya maleic imawoneka ngati makhiristo oyera okhala ndi kachulukidwe ka 1.484 g/cm3, kupereka zidziwitso zowonekera ku chiyero ndi mtundu wake.
Kuonetsetsa kuti mukugwira bwino ntchito ya maleic anhydride ndikofunikira kwambiri. Ndibwino kuti muzitsatira malangizo otetezeka kuphatikizapo S22 (Musapume fumbi), S26 (Mukakumana ndi maso, sukani nthawi yomweyo), S36/37/39 (Valani zovala zoyenera zodzitetezera, magolovesi ndi chitetezo cha maso / nkhope) ndi S45 ( Pakachitika ngozi kapena kusapeza bwino, pitani kuchipatala mwachangu). Chizindikiro C chikuwonetsa kuti ndi chiwopsezo chomwe chingakhale chowopsa ku thanzi ndipo chiyenera kuthetsedwa moyenera. Mawu owopsa akuphatikizapo R22 (owopsa ngati atawameza), R34 (amayambitsa kutentha) ndi R42/43 (akhoza kuchititsa chidwi pokoka mpweya ndi kukhudza khungu).
Maleic anhydride ali ndi khalidwe lokhazikika ndipo amagwiritsidwa ntchito kwambiri popanga utomoni, ndipo ndizofunikira kwambiri pamakampani opanga mankhwala. Zimapereka maubwino ofunikira monga kusintha kwa utomoni komanso kupangitsa kuti pakhale madzi. Kusinthasintha kwake komanso kuchitapo kanthu kumapangitsa kuti ikhale yabwino kwa mitundu yosiyanasiyana yamakampani ndi malonda, zomwe zimathandizira kupanga zinthu zapamwamba komanso zolimba.
Mwachidule, maleic anhydride, omwe amadziwikanso kuti MA, ndiwogwiritsidwa ntchito kwambiri popanga utomoni. Maleic anhydride, ndi khalidwe lake lokhazikika, kusungunuka kwa madzi, komanso kugwirizanitsa bwino ndi ma polima, kumapangitsa kuti utomoni ugwire ntchito ndipo umapangitsa kuti ukhale woyenera pa ntchito zosiyanasiyana. Komabe, chifukwa cha zoopsa zomwe zingachitike paumoyo wa maleic anhydride, kugwiritsa ntchito maleic anhydride kumafuna kutsatira mosamalitsa malangizo achitetezo. Ponseponse, maleic anhydride amagwira ntchito yofunika kwambiri pamakampani opanga mankhwala ndipo ndiyofunikira popanga utomoni wochita bwino kwambiri.
