The information in this MRL serves as a screening tool to help public health professionals decide where to look more closely to evaluate possible risk of adverse health effects from human exposure. When a fat is heated strongly in the presence of a dehydrating agent such as potassium bisulfate (KHSO4), the glycerol portion of the molecule is dehydrated to form the unsaturated aldehyde, acrolein (CH2=CH–CHO), which has the odor peculiar to burnt cooking grease. Colorless gas in smoke. The process uses air as the source of oxygen and requires metal oxides as heterogeneous catalysts:[5]. [19][20] E-cigarettes, used normally, only generate "negligible" levels of acrolein (less than 10 µg "per puff").[21][22]. More modern methods exist. Acrolein participates in many Diels-Alder reactions, even with itself. [5], A number of useful compounds are made from acrolein, exploiting its bifunctionality. In the 20th century, acrolein became an important intermediate for the industrial production of acrylic acid and acrylic plastics. The amino acid methionine is produced by addition of methanethiol followed by the Strecker synthesis. requires that releases or spills of one pound or more be reported to the National Response Center. Acrolein-13C3, >=99 atom % 13C, >=90% (CP), contains hydroquinone as stabilizer. The dehydration of glycerol has been demonstrated but has not proven competitive with the route from petrochemicals.[8]. Dates: Modify . acrolein definition: 1. a chemical substance with a strong, unpleasant smell that is used to make plastics 2. a chemical…. Small amounts of acrolein can be formed and can enter the air when trees, tobacco, other plants, gasoline, and oil are burned. It forms acetals readily, a prominent one being the spirocycle derived from pentaerythritol, diallylidene pentaerythritol. Acrolein is a colorless or yellow liquid with a disagreeable odor. [14], Connections exist between acrolein gas in the smoke from tobacco cigarettes and the risk of lung cancer. Small amounts of acrolein can be formed and can enter the air when trees, tobacco, other plants, gasoline, and oil are burned. A sample is heated with potassium bisulfate, and acrolein is released if the test is positive. The color and texture of the polymer depends on the conditions. 1.2 What happens to acrolein when it enters the environment? Please contact NTP, IARC, or EPA’s IRIS Hotline with questions on cancer and cancer classification. Acrolein is a relatively electrophilic compound and a reactive one, hence its high toxicity. [5] The monomer 3,4-epoxycyclohexylmethyl-3’,4’-epoxycyclohexane carboxylate is also produced from acrolein via the intermediacy of tetrahydrobenzaldehyde.

what is acrolein used for

The original industrial route to acrolein, developed by Degussa, involves condensation of formaldehyde and acetaldehyde: Acrolein may also be produced on lab scale by the reaction of potassium bisulfate on glycerol (glycerine).[9]. [citation needed], Acrolein is sometimes used as a fixative in preparation of biological specimens for electron microscopy.[10]. [12] Acrolein acts in an immunosuppressive manner and may promote regulatory cells,[13] thereby preventing the generation of allergy on the one hand, but also increasing the risk of cancer. Learn more. It is a colourless liquid with a piercing, disagreeable, acrid smell. It is also thought to be an intermediate in the Skraup synthesis of quinolines, but is rarely used as such due to its instability. It dissolves in water very easily and quickly changes to a vapor when heated. ATSDR can also tell you the location of occupational and environmental health clinics. 3 Chemical and Physical Properties Expand this section. 4 Related Records Expand this section. [11] In response to occupational exposures to acrolein, the US Occupational Safety and Health Administration has set a permissible exposure limit at 0.1 ppm (0.25 mg/m3) at an eight-hour time-weighted average. [5] The main metabolic pathway for acrolein is the alkylation of glutathione. Acrolein is used as a pesticide to control algae, weeds, bacteria, and mollusks. Acrolein (systematic name: propenal) is the simplest unsaturated aldehyde. Acrolein was first named and characterized as an aldehyde by the Swedish chemist Jöns Jacob Berzelius in 1839. The name is a contraction of ‘acrid’ (referring to its pungent smell) and ‘oleum’ (referring to its oil-like consistency). [24][25], Except where otherwise noted, data are given for materials in their. 2013-05-17. Quick reference guide providing information such as chemical and physical properties, sources of exposure, routes of exposure, minimal risk levels, children's health, and health effects for a substance. 888-232-6348 (TTY) has restricted the use of all pesticides containing acrolein and has also identified acrolein as a toxic waste; requires that companies that make, transport, treat, store, or dispose of acrolein comply with the regulations of a federal hazardous waste management program; has also proposed standards that limit the amount of acrolein put into publicly owned waste water treatment plants; and. 5 Chemical Vendors. The smell of burnt fat (as when cooking oil is heated to its smoke point) is caused by glycerol in the burning fat breaking down into acrolein. It is produced industrially from propylene and mainly used as a biocide and a building block to other chemical compounds, such as the amino acid methionine. Email: Contact CDC-INFO. Acrolein is mainly used as a contact herbicide to control submersed and floating weeds, as well as algae, in irrigation canals. [16] The acrolein content in cigarette smoke depends on the type of cigarette and added glycerin, making up to 220 µg acrolein per cigarette. Acrolein condenses with acetaldehyde and amines to give methylpyridines.
