| Questions And Answer | Back Directory | [Preparation]
1) Add a dehydrogenation catalyst to a fixed-bed dehydrogenation reactor; 2) Under hydrogen-containing and nitrogen- or inert gas-containing conditions, control the temperature, pressure and space velocity, and introduce trans-2-pentanol from the top of the fixed-bed dehydrogenation reactor downward through a metering pump to obtain the product trans-2-pentenal. |

CLEAR COLORLESS TO YELLOW LIQUID | [Uses]
(E)-2-Pentenal, is a flavor volatile found in tomato, virgin olive oil and sardine. | [Definition]
ChEBI: (E)-2-pentenal is a 2-pentenal in which the double bond has (E)-configuration. It is found in cigarette smoke, virgin olive oil, and milk. It has a role as a plant metabolite. | [General Description]
Trans-2-Pentenal (pentenal) is an α,β-unsaturated aldehyde that increases [Ca2+] in cultured neonatal rat trigeminal ganglion (TG) neurons. The gas-phase reactions of NO3 radicals with pentenal in pure N2, using a relative rate technique, was studied. | [Safety Profile]
Mutation data reported. When heated to decompositionit emits acrid smoke and irritating vapors. |
