How do you synthesize an acid anhydride?
Anhydrides of aromatic carboxylic acids are usually prepared by rereaction of powerful acylating agents (e.g., acyl chloride) with sodium salts of the same or another carboxylic acid or by treating acyl chloride with pyridine and decomposing the reaction mixture with water.What is the mechanism of anhydride synthesis?
Synthesis of anhydrides
The mechanism involves a double addition of the acid to the dicarbonate, affording a carboxylic anhydride and CO2.How are mixed anhydrides formed?
Mixed anhydrides were prepared by the reaction between palmitic acid which is taken as model of fatty acid, carboxylic acid chloride and triethylamine (1:1, 1:1,1 molar ratio) in hexan. The reaction mixture was stirred at room temperature for three hours.- Preparative Methods: acetic anhydride is prepared industrially by the acylation of Acetic Acid with Ketene . A laboratory preparation of acetic anhydride involves the reaction of sodium acetate and Acetyl Chloride followed by fractional distillation.
