Inombolo yeCAS:108-31-6

Imveliso yesakhiwo semolekyuli:

Iinkcazelo ngeMichiza:

I-Maleic Anhydride (MAN) yi-organic compound kunye ne-chemical formula C4H203.Yi-asidi ye-anhydride ye-asidi ye-maleic kwaye kwimeko yayo ecocekileyo yinto eqinileyo engenambala okanye emhlophe kunye nevumba le-acrid.I-Maleic anhydride ngokwenene yimolekyuli ephawulekayo kuba ineendidi ezimbini zokusebenza kweekhemikhali nto leyo eyenza ukuba ibe luncedo ngokukhethekileyo kwi-inchemical synthesis kunye nokusetyenziswa kwayo.

I-Maleic Anhydride yikhemikhali esebenza ngezinto ezininzi ephakathi kwaye isetyenziswa kwimimandla emininzi yoshishino lweekhemikhali.Ukuphela kokusetyenziswa kwayo kufana ne-feedstock kwimveliso ye-polyester resins (UPR) engafakwanga.
Ezi resins zisetyenziselwa zombini kwiglasi-eqiniswe kwaye kwizicelo ezingaqiniswanga.Ukusetyenziswa kokuphela kwe-UPR kubandakanya uluhlu olubanzi lwezicelo kumashishini okwakha, olwandle kunye neemoto.
Ukongezelela, i-Maleic Anhydride ingasetyenziselwa njengento eluhlaza kwimveliso ye-1,4-butanediol (BDO), i-gamma-butyrolactone kunye ne-tetrahydrofuran (THF).Kubalulekile ukugxininisa ukuba i-BDO yenye yeekhemikhali ezikhula ngokukhawuleza kwihlabathi kwiminyaka edlulileyo.

Isicelo:

Kwi-Diels-Alder syntheses (njenge-dienophile), ukuveliswa kwe-alkyd-uhlobo lwe-resin, i-dayi intermediates, i-pharmaceuticals, iikhemikhali zezolimo (i-maleic hydrazide, i-malathion), kwi-copolymerization reactions.

I-Maleic Anhydride yikhompawundi ye-heterocyclic esetyenziswa ekwenzeni iireyini zepolyester ezingaxutywanga.I-Maleic Anhydride inoluhlu olubanzi lwezinye izicelo;isetyenziswa kwi-synthetic tensides, insecticides, herbicides kunye nemichiza yokungunda.
