Section 21.131 - Sucrose octaacetate(a) Sucrose octaacetate is an organic acetylation product occurring as a white or cream-colored powder having an intensely bitter taste.(b)Free acid (as acetic acid). Maximum percentage 0.15 by weight when determined by the following procedure: Dissolve 1.0 gram of sample in 50 ml of neutralized ethyl alcohol (or S.D.A. No. 3-A, No. 3-C, or No. 30) and titrate with 0.1 N sodium hydroxide using phenolphthalein indicator. Percent acid as acetic acid=ml NaOH used*0.6/ weight of sample
(c)Insoluble matter. 0.30 percent by weight maximum.(d)Melting point. Not less than 78.0 °C.(e)Purity. Sucrose octaacetate 98 percent minimum by weight when determined by the following procedure: Transfer a weighed 1.50 grams sample to a 500 ml Erlenmeyer flask containing 100 ml of neutral ethyl alcohol (or S.D.A. No. 3-A, No. 3-C, or No. 30) and exactly 50.0 ml of 0.5 N sodium hydroxide. Reflux for 1 hour on a steam bath, cool and titrate the excess sodium hydroxide with 0.5 N sulfuric acid using phenolphthalein indicator. Percent sucrose octaacetate=(ml NaOH-ml H2 SO4 )*4.2412/weight of sample
