Guryaha Kiimikada:

Maleic Anhydride (MAN) waa unug dabiici ah oo leh qaacidada kiimikada C4H203. Waa anhydride-ka aashitada ee maleic acid oo xaaladdeeda saafiga ah waa mid aan midab lahayn ama adag oo cad oo leh ur aan lahayn. Maleic anhydride run ahaantii waa molecule cajiib ah in uu leeyahay laba nooc oo ka mid ah hawlaha kiimikada taas oo ka dhigaysa mid faa'iido gaar ah u leh isku dhafka kiimikada iyo codsiyada.

Maleic Anhydride waa dhexdhexaadiye kiimiko oo shaqo badan leh oo leh codsiyo dhinacyo badan oo warshadaha kiimikada ah. Isticmaalkeeda dhamaadka ugu weyn waa sida kaydka quudinta ee soo saarista resins polyester-ka (UPR).
Resins-yadan waxaa loo isticmaalaa labadaba muraayadaha lagu xoojiyay iyo codsiyada aan la xoojin. Isticmaalka dhamaadka UPR waxa ku jira codsiyo badan oo kala duwan xagga dhismaha, warshadaha badda iyo baabuurta.
Intaa waxaa dheer, Maleic Anhydride sidoo kale waxaa loo isticmaali karaa sida alaabta ceeriin ee wax soo saarka 1,4-butanediol (BDO), gamma-butyrolactone iyo tetrahydrofuran (THF). Waxaa muhiim ah in la muujiyo in BDO ay tahay mid ka mid ah kiimikooyinka ugu dhaqsaha badan adduunka sannadihii ugu dambeeyay.

Codsiga:

In Diels-Alder syntheses (sida dienophile), soo saarista alkyd-nooca resins, dhex-dhexaadinta dheeha, dawooyinka, kiimikooyinka beeraha (maleic hydrazide, malathion), ee falcelinta copolymerization.

Maleic Anhydride waa unug heterocyclic ah oo loo isticmaalo soo saarida xabagta polyesterka ee aan dheregsanayn. Maleic Anhydride waxa uu leeyahay tiro balaadhan oo ah codsiyada kale; waxaa loo isticmaalaa xayndaabyada synthetic, sunta cayayaanka, herbicides iyo fungicides.
