Applications

Phthaloyl chloride is used for the preparation of volatile acid chlorides from the acids. It acts as a trapping agent for the nitrite ion in the fluorodenitration of aromatic substrates with potassium fluoride. It serves as an additive in polymers and fibers to improve the color stability. It is used as an ingredient in ceramic mold binders, as a stabilizer for polymers and in reverse osmosis membranes.

Notes

Moisture sensitive. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with water, alcohols oxidizing agents and strong bases.

Literature References

Can be used for the preparation of volatile acid chlorides from the acids by exchange and distillation of the product from the reaction medium; see, e.g.: Org. Synth. Coll., 3, 422 (1955). For a one step conversion of ethyl esters to the corresponding acid chlorides, with loss of ethyl chloride, see: J. Org. Chem., 44, 2291 (1979).
