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.

Application


  • Hydroxyl radical reactions with diolefins in atmospheric and combustion environments: This study provides insights into the reactions of hydroxyl radicals with diolefins such as trans-1,3-Pentadiene, highlighting their significance in both atmospheric chemistry and combustion processes. This research helps in understanding the reactive pathways and kinetics that could inform both environmental and industrial applications of trans-1,3-Pentadiene (Khaled et al., 2019).

An indirect spectrophotometric method, based on the rapid Diels-Alder reaction between cisoid 1,3-dienes and tetracyanoethylene (TCNE) and the destruction of an aromatic-TCNE pi-complex, was developed to determine eleven 1,3-dienes in the 0.05-1.00 x 10(-3)M range. These dienes were: cyclopentadiene; 1,3-cyclohexadiene;
