Usage:

Acetyl chloride can be used as Acetylation agent in dye-stuffs and pharmaceuticals.

Acetyl chloride is a chemical for acetylation in the synthesis or derivatization of organic compounds.

Examples of acetylation reactions include acylation processes such as esterification (see below) and the Friedel-Crafts reaction.

CH3COCl + HO-CH2-CH3 → CH3-COO-CH2-CH3 + H-Cl

Frequently such acylations are carried out in the presence of a base such as pyridine, triethylamine, or DMAP, which act as catalysts to help promote the reaction and as bases neutralize the resulting HCl.

Such reactions will often proceed via ketene.

Acetylation is the introduction of an acetyl group via acylation using a reactant such as Acetyl chloride or acetic anhydride. An acetyl group is an acyl group having the formula -C(=O)-CH3

200KG/Drum. Never allow product to get in contact with water during storage. Keep tightly closed in a cool, dry, well-ventilated place Acetyl chloride is Stable under ordinary conditions but will fume when exposed to atmospheric moisture to form HCl and acetic acid.
