| | TRANS-1,3-PENTADIENE Usage And Synthesis |
| Definition | ChEBI: An alkadiene consisting of pentane with the two double bonds located at positions 1 and 3. | | General Description | Trans-1,3-Pentadiene spectra is recorded in the 5000-17500 cm(-1) region with conventional and intracavity laser photoacoustic spectroscopy. It can be determined by the spectrophotometric method based on the Diels-Alder reaction. In this reaction, cisoid 1,3-dienes and tetracyanoethylene (TCNE) react with an aromatic-TCNE pi-complex. | | Safety Profile | Poison by intravenous route. A very dangerous fire and explosion hazard when exposed to heat or flame; can react vigorously with oxidizing materials. When heated to decomposition it emits acrid smoke and irritating fumes. | | Purification Methods | Distil the diene from NaBH4. Purify it also by preparative gas chromatography. [Reimann et al.
