Luigi Chiozza (1828-1889) was an Italian chemist who made a detailed study of the preparation, properties, and reactions of organic acids. While studying the reaction of ammonium sulfide with nitrocinnamic acid, he discovered the new compound, carbostyril (2-hydroxyquinoline). He also synthesized monochlorobenzoic acid (o-chlorobenzoic acid) by treating the chlorination product of salicylic acid with phosphorus pentachloride with water. Alone, or with Gerhardt, he developed efficient processes for the preparation of simple and mixed acid anhydrides, as well as numerous new primaries, secondary, and ternary amides. His most important work was the artificial production of the essence of cinnamon (i.e., cinnamic aldehyde).

Palabras llave : Amides; anhydrides; cinnamon; vanilla.
