The determination of citric acid with pyridine and acetic anhydride has been investigated at reaction temperatures from 17 to 60° C. The optimum proportions of pyridine, acetic anhydride, water, and acetic acid for maximum color intensity and stability are given for each temperature. The procedure...
Cloprostenol (1), 1271 mg (0.2987 mmol), was dissolved in 15 mL of pyridine, 7 mg (0.06 mmol) of DMAP and 5.55 mL (5.974 mmol) of acetic anhydride were added with stirring, and the mixture was stirred for 12 h, Water, 5 mL, was then added, and the mixture was stirred for 2 ...
