I-Maleic Anhydride (MA) (i-CAS: 108-31-6) i-acid anhydride ye-maleic acid, i-odor stimulus ivumba elinamandla.I-Maleic anhydride ngokwenene yimolekyuli ephawulekayo kuba ineendidi ezimbini zokusebenza kweekhemikhali nto leyo eyenza ukuba ibe luncedo ngokukodwa kwi-chemical synthesis kunye nokusetyenziswa.
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 resin zisetyenziselwa zombini kwiglasi-eqiniswe kwaye kwizicelo ezingaqiniswanga.Ukusetyenziswa kokuphela kwe-UPR kubandakanya uluhlu olubanzi lwezicelo kumashishini okwakha, olwandle kunye neemoto.
Kwimveliso ye-polyester resins, i-fumaric acid, i-pesticides yezolimo, kunye ne-alkyl resins.
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.
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.
Ukuphefumla kubangela ukukhohlela, ukuthimla, ukucaphuka komqala.Uqhagamshelwano lwesikhumba lubangela ukucaphuka kunye nokubomvu.Imiphunga ibangela ukucaphuka kwamehlo kakhulu;photophobia kunye nombono kabini kunokwenzeka.
I-UN2215 Maleic Anhydride, iklasi yeHazard: 8;Iileyibhile: 8-Izinto eziNdlekayo.I-Maleic Anhydride ithengiswa kwaye ithuthwa ngendlela eqinileyo kunye netyhidiweyo.I-Maleic Anhydride etyhidiweyo ithuthwa kumaqondo obushushu ukusuka kwi-60 ukuya kwi-80°C kwizikhongozeli zetanki ezigqunywe kakuhle okanye iitanki zendlela ezinikwe izixhobo zokufudumeza.Ngendlela eqinileyo, inokuhanjiswa njenge-pastilles, ehlala ipakishwe kwiingxowa ze-polyethylene ze-25 kg kwaye zihanjiswe mhlawumbi nge-tank kaloliwe okanye ngelori.
Izinzile.Ukutsha.Ukungahambelani namanzi, ii-oxidizing agents ezinamandla, isinyithi se-alkali, iziseko ezomeleleyo, i-amines, isinyithi esixhaphakileyo, i-polymerization catalysts kunye ne-accelerators.
