4-Heptanone,3,5-dimethyl- - Introduction
3,5-dimethyl-4-heptanone (3,5-dimethyl-4-heptanone) is an organic compound with the chemical formula C10H20O. It is a colorless liquid with a fruity aroma. The following is a description of some properties, uses, methods and safety information about 3,5-dimethy1-4-heptanone:
Nature:
-Appearance: colorless liquid
-Molecular weight: 156.26g/mol
-Boiling point: 204-205 ° C
-Density: 0.807g/cm³
-Solubility: Soluble in alcohol and ether solvents, insoluble in water
-Toxicity: low, but still need to pay attention to the safety measures when using
Use:
-3,5-dimethy1-4-heptanone is mainly used as a solvent, intermediate or catalyst in chemical synthesis and organic synthesis reactions.
-It is also used as a flavoring agent in the flavor and fragrance industry to give the product fruit aroma.
Method:
-3,5-dimethyl-4-heptanone can be synthesized by the following steps: First, a series of chemical reactions are carried out by applying an acid catalyst on heptene to convert heptene into 2,4, 6-Trimethyl-2-heptene. Then, the 2,4, 6-trimethyl-2-heptene is partially oxidized and converted to 3,5-dimethyl-4-heptanol in the presence of oxygen. Finally, 3,5-dimethyl-4-heptanol is oxidized to give 3,5-dimethy1-4-heptanone.
Safety Information:
-3,5-dimethyl-4-heptanone is irritating to the skin and eyes, and direct contact should be avoided during operation. If contact occurs, immediately flush the affected area with plenty of water and seek medical help.
-When using 3,5-dimethyl-4-heptanone, you should maintain a well-ventilated working environment and avoid inhaling its vapor.
-Store it in a sealed container when storing, away from fire and oxidant, and avoid contact with air.
