The results indicate a mixture of triacetyl derivative with a lower derivative.( b ) Derivative with Hydrated Sodium Acetate-The procedure followed in this case was identical with that described above except t h a t 4 g. of crystalline sodium acetate and I O g. of galactan t o 50 g. of acetic anhydride were employed. A yield of 3 . 5 g. of the purified acetyl derivative was obtained.Approximately 0.3 g. of the derivative was hydrolyzed by boiling with I O O cc. of N / 4 under a reflux condenser for about 4 hrs., complete solution being obtained. The solution was then titrated with standard alkali in t h e usual manner. 0.2625 g. acetyl derivative gave 0.1297 g. acetic acid 0.3530 g. acetyl derivative gave 0.1722 g. acetic acid Per cent Acetic Acid Found Calculated for Duplicates Mean CsH8Ob(OC.CHs)z 49.40 49.78 49.09 48.78
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
