【摘要】 催化裂化汽油含有大量异构烯烃是醚化的理想原料，其中各组分烯烃合量测定对控制醚化条件非常重要。本文采用‘Ｈ－ＮＭＲ方法，在不需要标样和样品分离的条件下，测定了原料油中除Ｒ＿１Ｒ＿２Ｃ＝ＣＲ＿３Ｒ＿４以外的内烯烃和α－烯烃合量以及醚化汽油中的醚含量，其测量相对误差和标准偏差分别小于１７．２２％，０．８４％和０．６４％，０．９０％。更多还原

【Abstract】 )ethralization, the measure of a different kinds of alkene in wihic was important for to choose areasonable conditions of etheralization processes. In this paper, by using ’H-NMR technology and noneeding of standard sample and presparation, the percentage of several kinds of alkene in the feed gashave been measured with relative error and satndard deviation smaller than 17.22%, 0.84% excepting akind of R1R@C=CR3R4, as well as that of ether in the etheralization gasoline has been done with relativeerror and standard deviation smaller than 0.64%, 0.90%.更多还原
