WebPhosphorus (V) chloride is a solid which reacts with carboxylic acids in the cold to give steamy acidic fumes of hydrogen chloride.It leaves a liquid mixture of the acyl chloride and a phosphorus compound, phosphorus trichloride oxide (phosphorus oxychloride) – POCl 3. The acyl chloride can be separated by fractional distillation. WebThionyl chloride is used as a chlorinating reagent for acids and alcohols. It is often used in the preparation of a wide variety of alkyl chloride and acyl chloride compounds, which are useful in the manufacture of fine chemicals, drugs, drug intermediates and vitamins. It is used to prepare thionyl bromide and thionyl fluoride.

In organic chemistry, an acyl chloride (or acid chloride) is an organic compound with the functional group −C(=O)Cl. Their formula is usually written R−COCl, where R is a side chain. They are reactive derivatives of carboxylic acids (R−C(=O)OH). A specific example of an acyl chloride is acetyl chloride, CH3COCl. Acyl chlorides are the most important subset of acyl halides.
