| 1-OCTADECENE Usage And Synthesis |
| Description | Octadecene is a long-chain hydrocarbon and an alkene with the molecular formula C18H36. There are multiple structural isomers of octadecene, depending on the position of the double bond. 1-Octadecene, an alpha-olefin, is a relatively inexpensive solvent, with a boiling point of 315 °C.It is compatible with oleic acid.
| | Uses | 1-octadecene is a widely used solvent for high temperature nanocrystal synthesis (120–320 °C). Non-coordinating 1-octadecene (ODE)is another frequently used solvent and seems to be plagued less by impurities.Apart from its role as solvent, ODE has often been used as reagent in NC synthesis since ODE’sterminalalkene (vinyl) has inherent reactivity.
| | Purification method | Typical purification procedures (precipitation/redispersion cycles or size exclusion chromatography)fail to separate the poly(1-octadecene) impurity from the nanocrystal product.
| | Chemical Properties | CLEAR COLOURLESS TO AMBER LIQUID | | Uses | 1-Octadecene is used for the preparation of alkene-terminated silicon alkyl monolayers, nanocrystals, nanoplatelets and quantum dots. | | Uses | 1-Octadecene may be used in the preparation of monodisperse CuPd alloy nanoparticles (NPs). It may be used in the synthesis of magnetite nanocrystals. | | Definition | ChEBI: An octadecene with unsaturation at C-1. | | Synthesis Reference(s) | Journal of the American Chemical Society, 86, p. 3072, 1964 DOI: 10.1021/ja01069a020 | | General Description | The copolymerization of ethylene and 1-octadecene using a bridged metallocene has been studied. Monolayers of 1-octadecene were attached on a hydrogen-terminated (111) silicon surface via free-radical reaction. |
