| Crotonaldehyde Usage And Synthesis |
| Chemical Properties | Crotonaldehyde is water-white (turns paleyellow on contact with air) with an irritating, pungent, suffocating odor. The chemical can turn pale yellow when it contacts air. The chemical has a molecular weight of 70.1, a boiling point of 219°F, and a freezing point of -101°F. The vapor pressure is 30mm Hg at 25°C and the specific gravity is 0.87. The lower explosive limit is 2.1% and the upper explosive limit is 15.5%. Crotonaldehyde may be incompatible with caustics, ammonia, strong oxidizers, nitric acid, and amines. It also has the ability to polymerize at high temperatures.

| Uses | Crotonaldehyde (2-butenal, β-methyl acrolein, propylene aldehyde) is similar in structure to acrolein, as both are α,β-unsaturated aldehydes. This structural similarity leads to similar sensitizing and irritating properties of the two compounds. Crotonaldehyde is used industrially in the preparation of other chemicals (chiefly sorbic acid), flavoring agents, and can form endogenously and in the environment.
Crotonaldehyde is used in the manufacture ofbutyl alcohol, butyraldehyde, and in severalorganic synthesis. |
| Definition | ChEBI: Crotonaldehyde is an enal consisting of propene having a formyl group at the 1-position. |
| General Description | Water-white to straw-colored liquid with a pungent, suffocating odor. Used as a chemical intermediate in a variety of industrial processes (surfactants, textiles, paper, fuels, insecticides, leather tanning, etc.). Used in chemical warfare. |
| Air & Water Reactions | Highly flammable. |
| Reactivity Profile | Crotonaldehyde is an aldehyde. Crotonaldehyde can react violently with strong oxidizing reagents, e.g., reaction with conc. nitric acid leads to instantaneous ignition [Andrussow, L., Chim. Ind. (Paris), 1961, 86, p. 542]. In contact with strong acids or bases Crotonaldehyde will undergo an exothermic condensation reaction. Reaction with 1,3-butadiene is particularly violent [Greenlee, K. W., Chem. Eng. News, 1948, 26, p. 1985]. Crotonaldehyde may rapidly polymerize with ethyl acetoacetate (Soriano, D.S. et al. 1988. Journal of Chemical Education 65:637.). |
