摘要： Dodecene-1 and 1-tetradecene can be rectified from a mixture containing 1-dodecene and 1-tetradecene and triethylaluminum ("TEA") which has about the same normal boiling point as 1-dodecene and 1-tetradecene by feeding the above mixture to an intermediate point of a rectification column maintained under sufficient vacuum (e.g. 5-30 torr) such that the temperature at the intermediate feed point is about 250.degree.-260.degree. F. and the overhead distillation temperature is about 190.degree.-240.degree. F. The TEA which normally boils at about the same temperature as 1-dodecene and 1-tetradecene will exist as a dimer permitting part of the 1-dodecene and 1-tetradecene to distill overhead and most of the TEA to exit the bottom of the column.
摘要翻译：十二碳烯-1和1-十四碳烯可以从含有1-十二碳烯和1-十四碳烯和三乙基铝（“TEA”）的混合物中进行精馏，其通过将上述混合物加入到具有与1-十二碳烯和1-十四碳烯相同的标准沸点精馏塔的中间点保持在足够的真空（例如5-30托），使得中间进料点的温度为约250°-260°F，塔顶馏出温度为约190°-240°F。通常以与1-十二碳烯和1-十四碳烯相同的温度沸腾的TEA将作为二聚体存在，允许1-十二碳烯和1-十四碳烯的一部分蒸馏塔顶馏出物并且大部分TEA离开塔底。
