2-Heptanone 110-43-0
Category : Organic chemicals and Derivatives/Aroma compounds
CAS NO : 110-43-0 EC NO : 203-767-1 MF : C7H14O MW : 114.1855 Specification : 99% min Packing : 25kg，50kg 200kg Product description : What is the chemical of 2-Heptanone? Appearance: Colorless and transparent liquid, with a pear like fruity aroma, stable properties, slightly soluble in water, but miscible with most organic solvents ; Assay：99%min by GC ; IR Identity: conform to standard ; HNMR： conform to standard ; carbon spectrum: conform to standard ; Water by K. F.:0.5% max or as per the customer’s request ; Loss on drying:0.5% max. or as per the customer’s request ; Melting point: -35 °C; boiling point: 149-151 ° C (at 760 mmHg); ============================================================================ purpose 2-Heptanone has various industrial and commercial uses, mainly including: As a solvent: widely used in nitrocellulose, coatings, inks, and resins, it has low volatility and an evaporation rate of 60% of butyl acetate, which can improve the extensibility, moisture resistance, and glossiness of coatings. As spice raw material: it is used to prepare food essence such as cheese, banana, cream, coconut, etc. It is a FEMA 2544 certified food flavor. In chemical synthesis, it is used as an intermediate for organic synthesis, a standard substance for chromatographic analysis, and in the production of pesticides, pharmaceuticals, and carnation oil. Industrial application: As an inert reaction medium, it is used in the production processes of fibers, pharmaceuticals, and pesticides ============================================================================= synthetic route The synthesis methods of 2-heptanone mainly include the following: Hydroxyaldehyde condensation method: using acetone and butyraldehyde as raw materials, the intermediate is generated by aldol condensation dehydration, and then 2-heptanone is obtained by catalytic hydrogenation. This route has low raw material costs, simple steps, and is a relatively new process. Ethyl acetoacetate method: Ethyl acetoacetate is reacted with n-butane to produce n-butyl ethyl acetoacetate, which is then hydrolyzed and decarboxylated to produce 2-heptanone with a total yield of 58.9%. Other methods: Early studies also used KF-Al ₂ O3 as a catalyst for condensation reactions, or synthesized through the oxidation pathway of n-pentyl methyl ketone. Uses : widely used in nitrocellulose, coatings, inks, and resins Synonyms : Methyl amyl ketone;n-Amyl methyl ketone;Methyl n-pentyl ketone;1-Methylhexanal;2-Heptanal;2-Heptanon;2-Ketoheptane;2-Oxoheptane;Amyl-methyl-cetone;amyl-methyl-cetone(french);heptan-2-one;MAK; Molecular Structure :
