Because acetic anhydride is not stable in water, the conversion is conducted under anhydrous conditions. To a decreasing extent, acetic anhydride is also prepared by the reaction of ketene with acetic acid at 45–55 °C and low pressure (0.05–0.2 bar). [8] H 2 C=C=O + CH 3 COOH → (CH 3 CO) 2 O (ΔH = −63 kJ/mol)

acetyl chloride SOCl 2 acetic acid (i) Li[AlH 4], ether (ii) H 3 O + ethanol Two typical organic reactions of acetic acid Acetic acid undergoes the typical chemical reactions of a carboxylic acid. Upon treatment with a standard base, it converts to metal acetate and water. With strong bases (e.g., organolithium reagents), it can be doubly deprotonated to give LiCH 2 COOLi. Reduction of acetic ...
Ethyl acetate (systematically ethyl ethanoate, commonly abbreviated EtOAc, ETAC or EA) is the organic compound with the formula CH 3 CO 2 CH 2 CH 3, simplified to C 4 H 8 O 2.This flammable, colorless liquid has a characteristic sweet smell (similar to pear drops) and is used in glues, nail polish removers, and the decaffeination process of tea and coffee.
It is classified as an ester that is formed from 1-octanol (octyl alcohol) and acetic acid. It is found in oranges, grapefruits, and other citrus products. [10] Octyl acetate can be synthesized by the Fischer esterification of 1-octanol and acetic acid: CH 3 (CH 2) 7 OH + CH 3 CO 2 H → CH 3 (CH 2) 7 O 2 CCH 3 + H 2 O
Ethenone is very reactive, tending to react with nucleophiles to form an acetyl group. For example, it reacts with water to form acetic acid; [23] with acetic acid to form acetic anhydride; with ammonia and amines to form ethanamides; [24] and with dry hydrogen halides to form acetyl halides. [25]
Allyl acetate is produced industrially by the gas phase reaction of propene in the presence of acetic acid using a palladium catalyst: [2] [3] C 3 H 6 + CH 3 COOH + ½ O 2 → CH 2 =CHCH 2 OCOCH 3 + H 2 O. This method is advantageous because propene is inexpensive and a green chemical. Allyl alcohol is also produced primarily from allyl ...
Acetyl chloride was first prepared in 1852 by French chemist Charles Gerhardt by treating potassium acetate with phosphoryl chloride. [4]Acetyl chloride is produced in the laboratory by the reaction of acetic acid with chlorodehydrating agents such as phosphorus trichloride (PCl 3), phosphorus pentachloride (PCl 5), sulfuryl chloride (SO 2 Cl 2), phosgene, or thionyl chloride (SOCl 2).
