Code of Federal Regulations Title 27. Alcohol, Tobacco Products and Firearms § 27.21.131 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 usedx0.6/ 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.
