Uses |
It is primarily used in the production of sorbic acid, a preservative that inhibits yeast and mold growth. Crotonaldehyde also serves various industrial purposes, such as a warning agent in fuels, an alcohol denaturant, a stabilizer for tetraethyl-lead, and in the preparation of rubber accelerators and leather tanning agents. It is highly flammable, reacts violently with strong oxidizers, and can polymerize dangerously in certain conditions. Crotonaldehyde is severely irritating to the skin, eyes, and mucous membranes, and inhalation can cause respiratory distress and pulmonary edema. Despite its toxic nature, it is widely used in the manufacture of plastics, rubber, pharmaceuticals, and other industrial products. Handling crotonaldehyde requires careful safety precautions due to its reactivity and health hazards. |

Hydrogenation of crotonaldehyde has been studied over SiO2- and TiO2-supported Pt catalysts. Over Pt/SiO2, the selectivity to the primary products butyraldehyde and crotylalcohol depends critically on the Pt particle size; i.e., the selectivity to the unsaturated alcohol increases with increasing particle size. For large metal particles, the high fraction of Pt(111) surfaces is concluded to favor the adsorption of crotonaldehyde via the carbonyl bond. On small Pt particles, the high abundance of metal atoms in low coordination allows unconstrained adsorption of both double bonds.

The RAIRS data indicate that while acrolein initially adsorbs with its plane parallel to the surface and interacts mainly via the carbonyl group, crotonaldehyde adopts a more complex geometry where the main interaction to the metal is via a rehybridization of the CC double bond. It is suggested here that the changes in adsorption geometry induced by substitutions in the CC double bond may be responsible for the observed changes in the subsequent reactivity of the adsorbed unsaturated aldehydes.
