This reaction, first part of the synthesis starch octenyl succinic anhydride were synthesised by addition of 2-octenyl succinic anhydride aqueos solution to suspension modified wheat starch. After this part a certain amount of aluminum sulfate was added to starch octenyl succinic anhydride slurry.The results of SEM and FT-IR,27ALNMR, HNMR confirmed the fotmation of ester group and the cross-link with AL3+.Aluminum octenyl succinic anhydride (ASO) with starch. ASO is a unique, hydrophobically modified natural polymer, used in cosmetics and food industry
