Maleic Anhydride (MA) (CAS: 108-31-6) ndi asidi anhydride wa maleic acid, fungo lamphamvu lolimbikitsa.Maleic anhydride ndi molekyu yodabwitsa kwambiri chifukwa ili ndi mitundu iwiri ya magwiridwe antchito amakemiko kuti ikhale yothandiza kwambiri pakupanga mankhwala ndi kugwiritsa ntchito.
Maleic Anhydride ndi mankhwala ophatikizika apakati omwe amagwiritsidwa ntchito m'magawo angapo amakampani opanga mankhwala.Kugwiritsiridwa ntchito kwake kwakukulu kumakhala ngati chakudya chamagulu popanga unsaturated polyester resins (UPR).Ma resin awa amagwiritsidwa ntchito powonjezera magalasi komanso osalimbikitsidwa.Kumapeto kwa UPR kumaphatikizapo ntchito zosiyanasiyana m'mafakitale omanga, apanyanja ndi magalimoto.
Popanga ma polyester resins, fumaric acid, mankhwala ophera tizilombo, ndi ma alkyl resins.
Kuphatikiza apo, Maleic Anhydride angagwiritsidwenso ntchito ngati zopangira popanga 1,4-butanediol (BDO), gamma-butyrolactone ndi tetrahydrofuran (THF).Ndikofunika kutsindika kuti BDO ndi imodzi mwa mankhwala omwe akukula mofulumira kwambiri m'zaka zapitazi.
Maleic Anhydride ndi gulu la heterocyclic lomwe limagwiritsidwa ntchito popanga unsaturated polyester resins.Maleic Anhydride ali ndi ntchito zina zambiri;amagwiritsidwa ntchito popanga ma tensides, mankhwala ophera tizirombo, herbicides ndi fungicides.
Kukoka mpweya kumayambitsa kutsokomola, kuyetsemula, kukwiya kwapakhosi.Kukhudzana pakhungu kumayambitsa kuyabwa ndi kufiira.Nthunzi imayambitsa kukwiya kwambiri kwa maso;photophobia ndi masomphenya awiri akhoza kuchitika.
UN2215 Maleic Anhydride, Gulu la Zowopsa: 8;Zolemba: 8-Zinthu zowononga.Maleic Anhydride amagulitsidwa ndikusamutsidwa mumitundu yolimba komanso yosungunuka.Maleic Anhydride yosungunuka imatengedwa pa kutentha koyambira 60 mpaka 80 ° C m'matanki otetezedwa bwino kapena matanki apamsewu operekedwa ndi zida zotenthetsera.Mu mawonekedwe olimba, amatha kunyamulidwa ngati ma pastilles, omwe nthawi zambiri amadzaza m'matumba a polyethylene a 25 kg ndikunyamulidwa ndi tanki ya njanji kapena pagalimoto.
Wokhazikika.Zoyaka.Zosagwirizana ndi madzi, ma oxidizing amphamvu, zitsulo za alkali, maziko olimba, ma amine, zitsulo zodziwika bwino, zopangira ma polymerization ndi ma accelerator.
