Chemical compound

Acrolein (systematic name:propenal) is the simplestunsaturated aldehyde. It is a colorless liquid with a foul and acrid aroma. The smell of burnt fat (as whencooking oil is heated to itssmoke point) is caused byglycerol in the burning fat breaking down into acrolein. It is produced industrially frompropene and mainly used as abiocide and a building block to other chemical compounds, such as theamino acidmethionine.

History

[edit]

Acrolein was first named and characterized as an aldehyde by the Swedish chemistJöns Jacob Berzelius in 1839. He had been working with it as a thermal degradation product ofglycerol, a material used in the manufacture of soap. The name is a contraction of 'acrid' (referring to its pungent smell) and 'oleum' (referring to its oil-like consistency). In the 20th century, acrolein became an important intermediate for the industrial production ofacrylic acid and acrylic plastics.[4]

Production

[edit]

Acrolein is prepared industrially by oxidation ofpropene. The process uses air as the source of oxygen and requiresmetal oxides asheterogeneous catalysts:[5]

CH3CH=CH2 + O2 → CH2=CHCHO + H2O

About 500,000 tons of acrolein are produced in this way annually in North America, Europe, and Japan. Additionally, allacrylic acid is produced via the transient formation of acrolein.

Propane represents a promising but challenging feedstock for the synthesis of acrolein (and acrylic acid).The main challenge is in fact the overoxidation to this acid.

Whenglycerol (also called glycerin) is heated to 280 °C, it decomposes into acrolein:

(CH2OH)2CHOH → CH2=CHCHO + 2 H2O

This route is attractive when glycerol is co-generated in the production of biodiesel from vegetable oils or animal fats. The dehydration of glycerol has been demonstrated but has not proven competitive with the route frompetrochemicals.[6][7]

Niche or laboratory methods

[edit]

The original industrial route to acrolein, developed by Degussa, involvesaldol condensation offormaldehyde andacetaldehyde:

HCHO + CH3CHO → CH2=CHCHO + H2O

Acrolein may also be produced on lab scale by the action ofpotassium bisulfate on glycerol (glycerine).[8]

Reactions

[edit]

Acrolein is a relativelyelectrophilic compound and a reactive one, hence its high toxicity. It is a goodMichael acceptor, hence its useful reaction with thiols. It formsacetals readily, a prominent one being thespirocycle derived frompentaerythritol, diallylidene pentaerythritol. Acrolein participates in manyDiels-Alder reactions, even with itself. Via Diels-Alder reactions, it is a precursor to some commercial fragrances, includingmyrac aldehyde ("lyral") andnorbornene-2-carboxaldehyde.[5] The monomer3,4-epoxycyclohexylmethyl-3',4'-epoxycyclohexane carboxylate is also produced from acrolein via the intermediacy oftetrahydrobenzaldehyde.

Uses

[edit]

Military uses

[edit]

Acrolein was used in warfare due to its irritant and blistering properties. The French used the chemical in their hand grenades and artillery shells[9] duringWorld War I under the name "Papite".[10]

Biocide

[edit]

Acrolein is mainly used as acontact herbicide to control submersed and floating weeds, as well as algae, inirrigation canals. It is used at a level of 10 ppm in irrigation and recirculating waters. In theoil and gas industry, it is used as abiocide indrilling waters, as well as a scavenger forhydrogen sulfide andmercaptans.[5]

Chemical precursor

[edit]

A number of useful compounds are made from acrolein, exploiting its bifunctionality. The amino acidmethionine is produced by addition ofmethanethiol followed by theStrecker synthesis. Acrolein condenses with acetaldehyde and amines to givemethylpyridines.[11] It is also an intermediate in theSkraup synthesis ofquinolines.

Acrolein will polymerize in the presence of oxygen and in water at concentrations above 22%. The color and texture of the polymer depends on the conditions. The polymer is a clear, yellow solid. In water, it will form a hard, porous plastic.[citation needed]

Acrolein has been used as a fixative in preparation of biological specimens forelectron microscopy.[12]

Health risks

[edit]

Acrolein is toxic and is a strong irritant for the skin, eyes, and nasal passages.[5] The main metabolic pathway for acrolein is thealkylation ofglutathione. TheWHO suggests a "tolerable oral acrolein intake" of 7.5 μg per day per kg of body weight. Although acrolein occurs inFrench fries (and other fried foods), the levels are only a few μg per kg.[13] In response to occupational exposures to acrolein, the USOccupational Safety and Health Administration has set apermissible exposure limit at 0.1 ppm (0.25 mg/m3) at an eight-hour time-weighted average.[14] Acrolein acts in an immunosuppressive manner and may promote regulatory cells,[15] thereby preventing the generation of allergies on the one hand, but also increasing the risk of cancer.

Acrolein was identified as one of the chemicals involved in the2019 Kim Kim River toxic pollution incident.[16]

Cigarette smoke

[edit]

Connections exist between acrolein gas in the smoke fromtobacco cigarettes and the risk oflung cancer.[17] Acrolein is one of seventoxicants incigarette smoke that are most associated withrespiratory tractcarcinogenesis.[18] The mechanism of action of acrolein appears to involve induction of increasedreactive oxygen species andDNA damage related tooxidative stress.[19]

In terms of the "noncarcinogenic health quotient"[jargon] for components in cigarette smoke, acrolein dominates, contributing 40 times more than the next component,hydrogen cyanide.[20] The acrolein content in cigarette smoke depends on the type of cigarette and addedglycerin, making up to 220 μg acrolein per cigarette.[21][22] Importantly, while the concentration of the constituents in mainstream smoke can be reduced by filters, this has no significant effect on the composition of the side-stream smoke where acrolein usually resides, and which is inhaled bypassive smoking.[23][24]E-cigarettes, used normally, only generate "negligible" levels of acrolein (less than 10 μg "per puff").[25][26]

Chemotherapy metabolite

[edit]

Cyclophosphamide andifosfamide treatment results in the production of acrolein.[27] Acrolein produced during cyclophosphamide treatment collects in the urinary bladder and if untreated can cause hemorrhagic cystitis.

Endogenous production

[edit]

Acrolein is a component ofreuterin.[28] Reuterin can be produced by gut microbes when glycerol is present. Microbe-produced reuterin is a potential resource of acrolein.[29]

Analytical methods

[edit]

The "acrolein test" is for the presence ofglycerin orfats. A sample is heated withpotassium bisulfate, and acrolein is released if the test is positive. When a fat is heated strongly in the presence of a dehydrating agent such as potassium bisulfate (KHSO
4
), the glycerol portion of the molecule is dehydrated to form the unsaturatedaldehyde, acrolein (CH2=CH–CHO), which has the odor peculiar to burnt cooking grease. More modern methods exist.[13]

In the US, EPA methods 603 and 624.1 are designed to measure acrolein in industrial and municipalwastewater streams.[30][31]
