THE STUDY ON THE ENGINEERING CONDITION OF MAKING SUCCINC STARICH ESTER

This paper deals with the engineering condition of making succinic starch ester in water medium, by using succinic as modifying agent. It mainly discusses the influences of several important parameters to the product. These parameters envolve the original concentration of starch slurry, amount of succinic anhydride added to the slurry, the reaction temperature and the pH range of the reaction system. It also compares the fluidity of corn starch with that of succinic starch ester.
