Applications
Oxalyl chloride is mainly used as a catalyst in the oxidation of alcohols to the corresponding aldehydes and ketones. It is actively used for the synthesis of acid chlorides from acids. In the Fridel-Crafts acylation reaction, it reacts with aromatic compounds to get the corresponding acyl choride using aluminum chloride as catalyst. Further, it is utilized to prepare dioxane tetrketone, an oxide of carbon.

Solubility
Oxalyl chloride Slightly miscible with water.Miscible with ether, benzene and chloroform.

Notes
Moisture sensitive. Incompatible with bases, alcohols, water, amines and metals.
