alcoholBrnsted acidic ionic liquids were employed as a series of efficient catalysts and solvents in the esterification of alcohols with acetic anhydride at room temperature. Good yields, mild reaction conditions, short reaction time and no side reactions were achieved. The ionic liquids could be ...
acetic anhydride is an important acetylation test,, can make alcohol, phenol, ammonia and amine form acetate and acetamide compounds respectively. In the presence of Lewis acid, acetic anhydride can also cause acetylation of aromatic hydrocarbons or olefins. In the presence of sodium acetate, acetic...
Uncatalyzed esterification of acetic anhydride and isoamyl alcohol has been carried out in a miniaturized intensified reactor (MIR) to develop a kinetic equation using an ideal homogenous model. The effect of reaction temperature (65℃-85℃) and residence time (7.9 minutes – 180.3 minutes) at ...
1974). Acetic anhydride is miscible with polar solvents and dissolves in cold alcohol with slow decomposition. The solubility of acetic anhydride in water at 20°C is 2.6wt%, with slow decomposition; the solubility of water in acetic anhydride at 15°C is 10.7 wt%, with gradual decomposition...
A variety of primary alcohols and phenols were reacted with acetic anhydride at room temperature in the presence of sodium bicarbonate to produce corresponding esters in good to excellent yields. The acetylation of 4-nitrobenzyl alcohol was also carried out using other bicarbonates and carbonates. ...
An alcohol evaporator for production of acetic acid and acetic anhydride exploded during operation. 一种用于生产醋酸和醋酸酐的酒精蒸发釜在服役中发生了爆炸。 www.chemyq.com 9. The reaction of benzyl alcohol with acetic anhydride over six of supported-ionic liquids were investigated. 以乙酸酐醇解反应...
Initially, benzyl alcohol (1 mmol) was chosen as a model substrate for the acylation reaction. The reaction of this alcohol with acetic anhydride (2 equivalent) in acetonitrile (2 mL) in the presence of 0.01 molar equivalent of SnIV(tpp)(OTf)2 at room temperature was completed in 1 min ...
