4-heptanone

4-heptanone (English, 4-heptanone) is one of the structural isomers of heptanone and is one kind of ketone. Because it was molecular formula C₇H₁₄O, molecular weight 114.19 and just did the molecular structure with two propyl groups (C₃H₇) to ketone, I was called dipropyl ketone (English, dipropylketone). In addition, I have been called butylon (English, butyrone). But I unify it for notation called 4-heptanone in this report as follows. I correspond to the fourth kind dangerous materials second oil to fix for the Fire Services Act [¹].

Property

4-heptanone is melting point -33 degrees Celsius [²], boiling point 144 degrees Celsius in ordinary pressure [²]

^[3].

Therefore, 4-heptanone exists as a liquid in normal temperature ordinary pressure. In addition, the specific gravity of 4-heptanone in 15 degrees Celsius that assumed water of 4 degrees Celsius a standard material 0.8205 [³] similarly the specific gravity in 20 degrees Celsius 0.8145 [²].

As for the refractive index of 4-heptanone in 20 degrees Celsius for the D string of sodium, 1.4069 [²] is the same; the refractive index in 22 degrees Celsius 1.40732 [³].

It is indissolubility in water, but dissolves in ethanol well [²].

In addition, with a property to stimulate a mucous membrane [²].

In addition, when there is chromium oxide (VI), 4-heptanone is oxidized and disintegrates to propionic acid and butyric acid [³].

Synthetic law

I can compose 4-heptanone by some methods.

• I let butyric acid go through on the powder of heated zinc to 330 degrees Celsius [³].
• I wash down butyric acid on calcium carbonate (lime) which heated up to 450 degrees Celsius [²].
• I perform distillation of butyric acid calcium [³].
• I heat butyric acid sodium to 440 degrees Celsius under reduced pressure [²].

Other

The CAS registration number of 4-heptanone is 123-19-3.
