ETHYLCARBOXALDEHYDE

Ethylcarboxaldehyde is a colorless, flammable liquid with a slightly fruity odor and is produced on a large scale industrially.

Properties of Ethylcarboxaldehyde:
Ethylcarboxaldehyde is a colorless, flammable liquid, having a suffocating odor.
Ethylcarboxaldehyde should be used as a chemical intermediate only. 

Ethylcarboxaldehyde undergoes reactions typical for the low molecular weight aldehydes, which, because of the terminal carbonyl group, are very reactive. 
Contamination or the exposure to elevated temperatures may induce a hazardous polymerization.
Ethylcarboxaldehyde is readily oxidized if in contact to oxygen and should therefore be stored under inert gases. 

Physical Properties:
Ethylcarboxaldehyde is a colorless, flammable liquid with a suffocating fruity odor.
The odor threshold for Ethylcarboxaldehyde is 1 part per million (ppm).

The chemical formula for Ethylcarboxaldehyde is C3H6O, and the molecular weight is 58.08 g/mol. 
The vapor pressure for Ethylcarboxaldehyde is 317 mm Hg at 25 °C.

Production of Ethylcarboxaldehyde:
Ethylcarboxaldehyde is mainly produced industrially by hydroformylation of ethylene:
CO + H2 + C2H4 → CH3CH2CHO

In this way, several hundred thousand tons are produced annually.

Laboratory preparation of Ethylcarboxaldehyde:
Ethylcarboxaldehyde may also be prepared by oxidizing 1-propanol with a mixture of sulfuric acid and potassium dichromate. 
The reflux condenser contains water heated at 60 °C, which condenses unreacted propanol, but allows Ethylcarboxaldehyde to pass. 

The Ethylcarboxaldehyde vapor is immediately condensed into a suitable receiver. 
In this arrangement, any Ethylcarboxaldehyde formed is immediately removed from the reactor, thus Ethylcarboxaldehyde does not get over-oxidized to propionic acid.

General Manufacturing Information of Ethylcarboxaldehyde:

Industry Processing Sectors:
All Other Basic Organic Chemical Manufacturing
Paint and Coating Manufacturing
Petrochemical Manufacturing

Reactions of Ethylcarboxaldehyde:
Ethylcarboxaldehyde exhibits the reactions characteristic of alkyl aldehydes, e.g. hydrogenation, aldol condensations, oxidations, etc. 
Ethylcarboxaldehyde is the simplest aldehyde with a prochiral methylene such that α-functionalized derivatives (CH3CH(X)CHO) are chiral.

Extraterrestrial Occurrence of Ethylcarboxaldehyde:
Ethylcarboxaldehyde along with acrolein has been detected in the molecular cloud Sagittarius B2 near the center of the Milky Way Galaxy, about 26,000 light years from Earth.
Measurements by the COSAC and Ptolemy instruments on comet 67/P's surface, revealed sixteen organic compounds, four of which were seen for the first time on a comet, including acetamide, acetone, methyl isocyanate and Ethylcarboxaldehyde.

Action Mechanism of Ethylcarboxaldehyde:
Inhibition of intercellular communication is an important feature in the tumor promotion phase of a multistage carcinogenesis model. 
In atherosclerosis inhibition of cell-cell communication by atherogenic compounds, e.g., low density lipoproteins (LDL), also seems to be important. 

For testing atherogenic compounds we used an atherosclerosis relevant cell type, namely human smooth muscle cells. In order to investigate which part of the LDL particle would be involved in inhibition of metabolic co-operation between human smooth muscle cells in culture several fatty acids and their breakdown products were tested, namely aldehydes. 
Unsaturated C-18 fatty acids markedly influenced gap-junctional intercellular communication (GJIC), whereas saturated (C18:0, C16:0) and unsaturated fatty acids with > 20 carbon atoms did not inhibit GJIC. 

In the case of oleic and elaidic acid, orientation seemed important; however, after exposure to palmitoleic and palmitelaidic acid no differences were found. 
The most potent inhibitor of GJIC was linoleic acid, which inhibited GJIC by 75%. 

No correlation was found between degrees of unsaturation and ability to inhibit GJIC. 
Of the tested aldehydes, hexanal, Ethylcarboxaldehyde, butanal and 4-hydroxynonenal did significantly inhibit GJIC, while pentanal had no effect. 
Since modification of LDL was shown to be important in order for LDL to inhibit GJIC, these results show that fatty acids and their oxidative breakdown products may be of importance for the inhibition of GJIC by LDL.
