Determination of Hydroxyl Groups in Organic Compounds

REACTIONS OF ATOMS AND FREE RADICALS IN SOLUTION. XXVI. COMPARISON OF THE REACTIONS OF LEAD TETRAACETATE AND ACETYL PEROXIDE WITH ACETIC ACID AND ISOPROPYL ETHER1

“…However, a reaction similar to lOd may here play an important role. Free methyl and free acetoxy radicals attack the solvent as in equation 18 and to a very minor extent (if at all) the lead tetraacetate as in equations 15 and 16.…”

“…124.5-125°). The isopropyl alcohol (0.0035 mole) was determined by the method of Freed and Wynne (18), and the carbanilic ester (m.p. 87-87.5°) was made.…”

Facile Preparation of Peracetates and Per-3-bromobenzoates of α-Mono- and Disaccharides

“…During the acetylation of glucose, acetic anhydride is almost always the reagent of choice, and the catalysts most frequently employed are zinc chloride [ 14 ] (or other Lewis acids), sodium acetate [ 15 ] and pyridine [ 16 ]. The acetylation of other sugars can be carried out under similar conditions.…”

Reactions of Atoms and Free Radicals in Solution. Xxvii. The Decomposition of Diacetyl Peroxide in Alcohols

“…Molecular weights were determined cryscopically in benzene. The weight in grams of substance containing one equivalent of hydroxyl (acetylation number) was determined by the method of Freed and Wynne (14).…”
