ULWAKHIWO:
I-Maleic Anhydride (MAN) yi-organic compound ene-chemical formula C4H203. Yi-acid anhydride ye-maleic acid kwaye kwimeko yayo ecocekileyo yi-solid engenambala okanye emhlophe enevumba elibi. I-Maleic anhydride yi-molecule emangalisayo kuba ineentlobo ezimbini zomsebenzi weekhemikhali okwenza ukuba ibe luncedo ngokukodwa ekuqulunqweni kweekhemikhali nasekusetyenzisweni kwazo.
I-Maleic Anhydride yikhemikhali esebenza ngeendlela ezininzi esetyenziswa kwiindawo ezahlukeneyo zoshishino lweekhemikhali. Eyona nto isetyenziswa kakhulu kukutya kwayo ekuveliseni ii-resin ze-polyester ezingagcwaliyo (UPR).
Ezi resin zisetyenziswa zombini kwizicelo eziqinisiweyo ngeglasi nakwizicelo ezingaqinisiweyo. Ukusetyenziswa kwe-UPR end kuquka uluhlu olubanzi lwezicelo kwimizi-mveliso yokwakha, eyolwandle neyeemoto.

Ukusetyenziswa
I-Maleic Anhydride yi-heterocyclic compound esetyenziswa ekwenzeni ii-resin ze-polyester ezingagcwaliyo. Inezinye iindlela ezininzi zokusetyenziswa; isetyenziswa kwi-synthetic tensides, kwi-insecticides, kwi-herbicides nakwi-fungicides.
I-anhydride ye-Maleic isetyenziswa kwi-Diels-Alder syntheses (njenge-dienophile), ukwenziwa kwee-resin zohlobo lwe-alkyd, ii-dye intermediates, amayeza, iikhemikhali zezolimo (i-maleic hydrazide, i-malathion), kwi-copolymerization reactions.
