Abstract10,11‐Dioctyleicosane, a star‐shaped hydrocarbon, has been successfully synthesized from 9‐octadecene (a product from metathesis of methyl oleate or ethyl oleate) through dimerization followed by hydrogenation. The product was determined by13C nuclear magnetic resonance spectroscopic and gas chromatography/mass spectrometric techniques. This hydrocarbon likely exhibits lubricating properties that can be used as high‐performance functional fluids in automotive lubrication. We also report the presence of a novel product, a trimer that was formed during the synthesis.
摘要 10,11-二辛基二十烷是一种星形碳氢化合物,它是由 9-十八烯(油酸甲酯或油酸乙酯的偏析产物)通过二聚化然后加氢成功合成的。该产品通过 13C 核磁共振光谱和气相色谱/质谱技术进行了测定。这种碳氢化合物可能具有润滑特性,可用作汽车润滑油中的高性能功能液。我们还报告了一种新型产物,即在合成过程中形成的三聚体。
