Versuchsvorschrift

The adipate/acetate of amylopectin potato starch was prepared using a 1:20 mixture. 810 gram dry starch was suspended in water to 39% suspension. The pH was adjusted to 8.5 with a 4.4% (w/w) sodium hydroxide solution and 1.3 ml of 30% of H2O2 solution were added. Then 6 g of 1:20 adipic anhydride reagent was added drop wise keeping the pH at 8.5 with a 4.4% (w/w) sodium hydroxide solution. Afterwards 41 grams of acetic anhydride was added drop wise to a pH 8.5. The acetic anhydride reaction was performed in approx. 1.5 hours. After the acetic anhydride dosage the suspension was stirred for 10 minutes at pH 8.5. Then the suspension was neutralised with sulphuric acid to pH 5.5 and the final product was dewatered, washed and dried using methods known to the art.
