Istaarj La Bedelay
Waxa kale oo loo yaqaan derivatives istaarijka, kuwaas oo ay soo saaraan jir ahaan, kiimiko ahaan ama enzymatically lagu daaweeyay istaarijka wadaniga ah si loo beddelo, loo xoojiyo ama loo wiiqo hantida cusub ee kala-goynta molecular, dib-u-habaynta ama soo bandhigida kooxo cusub oo beddela.Waxaa jira siyaabo badan oo wax looga beddelo istaarijka cuntada, sida karinta, hydrolysis, oxidation, bleaching, oxidation, esterification, etherification, crosslinking iyo iwm.
