TSARI:
Maleic Anhydride (MAN) wani sinadari ne na halitta wanda ke da dabarar sinadarai ta C4H203. Shi ne acid anhydride na maleic acid kuma a cikin tsarkinsa, yana da tauri mara launi ko fari mai ƙamshi mai kamshi. Maleic anhydride hakika wani sinadari ne mai ban mamaki domin yana da nau'ikan ayyuka guda biyu na sinadarai wanda hakan ya sa yake da amfani na musamman a fannin hada sinadarai da aikace-aikace.
Maleic Anhydride wani sinadari ne mai aiki da yawa wanda ake amfani da shi a fannoni daban-daban na masana'antar sinadarai. Babban amfani da shi shine a matsayin abinci mai gina jiki wajen samar da resin polyester mara cika (UPR).
Ana amfani da waɗannan resins a aikace-aikacen da aka ƙarfafa gilashi da kuma a aikace-aikacen da ba a ƙarfafa ba. Amfanin ƙarshe na UPR ya haɗa da aikace-aikace iri-iri a masana'antar gini, ruwa da motoci.
