Chemical Properties:

Maleic Anhydride (MAN) ndi organic pawiri ndi mankhwala chilinganizo C4H203.Ndi asidi anhydride wa maleic acid ndipo mumkhalidwe wake woyera ndi wopanda mtundu kapena woyera wolimba ndi fungo la acridi.Maleic anhydride ndi molekyu yodabwitsa kwambiri chifukwa ili ndi mitundu iwiri ya magwiridwe antchito amakemiko omwe amawapangitsa kukhala othandiza mwapadera pakupanga ndi kugwiritsa ntchito kwake.

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.
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.

Ntchito:

Mu Diels-Alder syntheses (monga dienophile), kupanga alkyd-mtundu wa resins, dye intermediates, mankhwala, mankhwala ulimi (maleic hydrazide, malathion), mu copolymerization reactions.

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.
