3-heptanone is an important organic chemical raw material, widely used in medicine, pesticides, spices, dyes and other fields. This article will detail the properties and uses of 3-heptanone.

1. the properties of 3-heptanone

1. Physical properties

3-heptanone is a colorless transparent liquid with a special smell. It has a boiling point of 164~165 ℃, a density of 0.825g/cm3, a refractive index of 1.4058 and a flash point of 52 ℃. 3-heptanone is insoluble in water, but can be miscible with alcohol, ether, benzene and other organic solvents.

2. chemical properties of

3-heptanone with ketone generality, can occur addition, oxidation, reduction, condensation and other reactions. For example, 3-heptanone can react with hydrogen to generate 3-heptanol; Condensation reaction with alcohol to generate ketoaldehyde; Oxidation by acidic potassium permanganate to propionic acid, etc.

2. 3-heptanone use

1.

in the field of medicine 3-heptanone can be used as pharmaceutical intermediates for the synthesis of antibacterial drugs, anti-inflammatory drugs, anticancer drugs and other drugs. For example, 3-heptanone can synthesize fluoroquinolone antibacterial drugs such as ciprofloxacin, which have a broad-spectrum antibacterial effect on a variety of bacteria and are widely used in the treatment of infectious diseases.

2.

in the field of pesticides 3-heptanone can also be used as pesticide intermediates for the synthesis of pesticides, fungicides, herbicides and other pesticides. For example, 3-heptanone can synthesize insecticides such as imidacloprid, which have efficient killing effects on a variety of pests and are widely used in crop control.

3. spice field

3-heptanone has a special smell, can be used as spices for food additives, daily chemical products, etc. For example, 3-heptanone can be used to prepare fruit flavors such as strawberries and raspberries, and added to foods to enhance taste and aroma.

4. Other fields

In addition to the above several fields, 3-heptanone can also be used to synthesize dyes, solvents, plasticizers, etc. For example, 3-heptanone can be used as a solvent for the production of inks, coatings and other products; as a plasticizer for the production of plastic products, can increase the flexibility and ductility of plastics.

In conclusion, 3-heptanone, as an important organic chemical raw material, has been widely used in the fields of medicine, pesticides, spices and so on, providing important material support for the development of these fields.
