123-19-3 Usage

Health Hazard

Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.

Purification Methods

Dry 4-pentanone with CaSO4, then distil it from P2O5 under nitrogen. [Beilstein 1 IV 3323.]

Description

4-Heptanone is an organic ketone containing seven carbon atoms. It can be found in urine samples of human being. It arises from in vivo beta-oxidation of 2-ethylhexanoic acid (EHA) from plasticisers, which is similar to the formation of 3-heptanone from valproic acid. It is mainly used as the solvents of nitrocellulose, nitrocellulose paint and synthetic resin and as the raw materials of organic synthesis. It can also be used as a internal standard of gas chromatography-mass spectrometry for the analysis of 3-monochloro-1, 2-propane diol which is a potential carcinogen found in soy sauce. It can be synthesized during the reaction of 1-butanol over base catalysts such as MgO.

Reactivity Profile

4-Heptanone is incompatible with the following: Oxidizers .

Chemical Properties

colourless liquid

Air & Water Reactions

Flammable. Insoluble in water.

Catalysed synthesis of 4-Heptanone (cas 123-19-3) from 1-butanol09/07/2019

While investigating the reaction of 1-butanol over base catalysts, such as MgO, we observed the formation of small amounts of 4-heptanone. Further studies revealed that a CeO2/MgO catalyst gave good selectivity to this product. To optimise the reaction and determine the reaction mechanism a seri...detailed
