Maleik anhidrid, doymam poliester reçinelerinin, tarm kimyasallarnn, yalayc katk maddeleri ve gda asitleri gibi önemli ürünlerin sentezinde bir reaktan olarak kullanlabilir. Maleik asidin yaps dört karbon molekülünden ve her iki uçtaki karboksilat gruplarndan oluur ve merkezi karbon atomlar arasnda çift ba bulunur.
kullanm: Dünya maleik anhidrit üretiminin yaklak% 50’si doymam polyester reçinelerin (UPR) imalatnda kullanlr. Krlangç cam elyaflar, elence tekneleri, banyo armatürleri, otomobiller, tanklar ve borular gibi geni bir uygulama yelpazesinde kullanlan fiberglas takviyeli plastikler üretmek için UPR’ye eklenir.Maleik anhidrit için bir baka pazar, benzin ve dizel motor karter yalarnda datclar ve korozyon inhibitörleri olarak kullanlan yalayc ya katklardr. Diels-Alder (dien) sentezinde, reçineler, farmasötikler ve tarmsal kimyasallarn hazrlanmasnda kopolimerizasyon reaksiyonlarnda kullanlr.
Maleic anhydride may be used in the synthesis of unsaturated polyester resins and as a reactant in synthesizing important products such as agricultural chemicals, lubricant additives and food acidulatents. The structure of maleic acid consists of four carbon molecules along with carboxylate groups on either ends, with a double bond between the central carbon atoms.
uses: Around 50% of world maleic anhydride output is used in the manufacture of unsaturated polyester resins (UPR). Chopped glass fibers are added to UPR to produce fibreglass reinforced plastics which are used in a wide range of applications such as pleasure boats, bathroom fixtures, automobiles, tanks and pipes. Another market for maleic anhydride is lubricating oil additives, which are used in gasoline and diesel engine crankcase oils as dispersants and corrosion inhibitors.Used in copolymerization reactions, in the Diels-Alder(diene)synthesis, in the preparation of resins, pharmaceuticals and agricultural chemicals.
