摘要

依据在20℃钠D线折光率实测值

在20℃钠D线折光率计算值

分子量及每一分子内所含双键数间之相互关系

推衍得一简易方法

用以测定纯不饱和烃及石油分馏油份之双键率(Double Bond Index).所需由实验测得之数据为试料之(甲)在20℃钠D线折光率

(乙)在20℃时之密度

(丙)中间沸点(Mid-boiling point)

及(丁)含氢重量百分数.用本法测得双键率值

与用尼蒲金(Lipkin)

圣金(Sankin)及马丁(Martin)三氏法测得双键率值适相吻合.因此

用本法所测得之双键率

足资用以鉴定石油分馏油份内所含芳香族烃及烯(?)烃之主要型式.惟需指明者

即在依据本法测得之双键率

用以鉴定石油分馏油份内所含不饱和烃之主要型式时

必须测定由石油分馏油份内提出仅含不饱和烃浓缩物之双键率.

Abstract

1. A simple method is presented for determining double bond index of pure unsaturated hydrocarbons

petroleum fractions and other hydrocarbon mixtures based on a correlation of observed refractive index

calculated refrac-tive index

molecular weight and the number of double bonds per molecule. The data neccessary are: (a) mid-boiling point

(b) refractive index at 20℃ for sodium D line

(c) density at 20℃ and (d) weight percent hydrogen of the sample. 2. The double bond index determined by the present method for pure unsaturated hydrocarbons and unsaturated concentrate from petroleum fractions agree fairly well with that determined by Lipkin

Sankin

and Martins method

but there is some discrepancy for petroleum fractions containing saturated hy-drocarbons. 3. For identifying the predominant type of aromatic or olefinic hydrocar-bons in a petroleum fraction

the double bond index should be determined on unsaturated concentrate when the present method is used.
