我们描述了一种估计长于辛烯的直链烯烃混合物中双键位置的新方法。该方法需要大约一克烯烃和由均相复分解催化剂催化的5-10分钟的反应。由气相色谱测定的产物混合物的碳数分布取决于双键异构体在起始混合物中的分布。我们描述了一种使用最终碳数分布来确定起始混合物中双键位置的计算机算法。例子是基于十四烯、十六烯和十八烯。
We describe a new method for estimating the positions of double bonds in mixtures of linear olefins longer than octene. The method requires about a gram of olefin and a 5-10 min reaction catalyzed by a homogeneous metathesis catalyst. The carbon number distribution of the product mixture, as determined by gas chromatography, depends upon the distribution of double-bond isomers in the starting mixture. We describe a computer algorithm for using the final carbon number distribution to determine the locations of double bonds in the starting mixture. Examples are based on tetradecenes, hexadecenes, and octadecenes.
