Detecting the emitted vapors from overheated polyvinyl chloride (PVC) cables has proven to be an effective way to monitor early elec. fires. In this work, the vapors generated from both conventional and phthalate-free PVC cables were first examined 2-ethylhexanol (2-EH) was found to be ubiquitously present and can serve as a universal signature gas for the overheated cables. Sea urchin-like ZnO was then prepared via a template-free hydrothermal route for sensing 2-EH. A facile immersion-calcination method was adopted to further modify ZnO, and different CuO/ZnO and Cr2O3/ZnO composites were obtained. The surface modification led to significant improvement in the response of the ZnO sensors to 2-EH. Cable fire simulation tests were also conducted to evaluate the response of optimized gas sensors to overheated conventional and phthalate-free cables in comparison with a typical smoke detector. This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7Recommanded Product: 5444-75-7).
2-Ethylhexyl benzoate (cas: 5444-75-7) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Recommanded Product: 5444-75-7
