Description and Uses
4-Heptanone has a penetrating odor and burning taste. It is prepared by passing butyric acid over a wood coal at 425°C and then over cerium oxide at 500°C or over thorium oxide; also over manganese oxide at 400 - 425°C.
4-Heptanone is used as a solvent for nitrocellulose as well as in organic synthesis. It is involved in the preparation of flavorings. It is used as an intermediate in the synthesis of active pharmaceutical ingredients. Further, it is used in paints and coatings.
