- P2O5 / SiO2 as a mild and efficient reagent for acylation of alcohols, phenols and amines under solvent-free conditions
-
P2O5 / SiO2 is a highly efficient reagent for the acetylations of a variety of alcohols, phenols and amines with acetic anhydride under solvent-free conditions. Primary, secondary, allylic and benzylic alcohols, diols and phenols with electron-donating or withdrawing substituents can be easily acetylated in good to excellent yield.

- THE SOLUBILITY OF CARBON DIOXIDE IN SOME ACETIC ACID ESTERS
-
The absorption of carbon dioxide in organic solvents containing acetyl groups (ethylene glycol diacetate, diethylene glycol diacetate, triethylene glycol diacetate, propylene glycol diacetate, ethyl cellosolve acetate, 1,4-butanediol diacetate, glycerol triacetate and β-phenyl acetate) is studied. Bunsen absorption coefficients in the range of 5 to 50 atm and at 25 deg C are obtained. Some considerations about the correlation between absorptive capacity and the molecular structure of these organic compounds are presented.
