摘要
用ＧＣＭＳ研究了低温焦油第４ 和第５ 蒸馏馏分的组成和统计平均结构。研究表明， 平朔煤低温焦油第４（２３０～２７０ ℃）和第５（２７０ ～３４０ ℃） 蒸馏馏分，由脂肪烃类化合物和非脂肪烃类化合物两大类组成。第４ 和第５ 馏分的平均分子量分别为２８０ ．２ 和２９６ ．７。第４ 蒸馏馏分中的非脂肪烃化合物主要由酚类２２ ．４４ ％ 和取代萘酚６２ ．７３ ％ 组成。第５ 蒸馏馏分中的非脂肪烃化合物主要由酚类８ ．６９ ％ ，芳香基醇４２．５３ ％ 及多烷基和烷氧基取代的芳香化合物２８．６７ ％ 组成。第４ 和第５ 馏分的统计平均结构分别为羟基二甲基茚和二甲基萘酚。
The component characteristics and statistical structure of the 4th(230～270 ℃) and 5th (270～340 ℃) distiled fractions of a kind of low temperature tar were studied using GC MS. The studies on component characteristics showed that (1) the compounds in the distilled fractions can be classified into paraffinic compounds and non paraffinic compounds. The average molecular weight of the paraffinic compounds for 4th distilled fraction in which there is a few olefinic compounds, and 5th distilled fraction is 280.2 and 296.7 respectively. (2) the non paraffinic compounds in the 4th distilled fraction was mainly dominated by phenols 22.44 % and substituted naphthalene 62.73 %. The non paraffinic compounds in the 5th distilled fraction was mainly composed of phenols 8.69 %, aromatic radical alcohol 42.53 % and polyalkyl and alkosy substituted aromatic 28.67 %. The details of the components in the specific tar have made a base for the utilization of the tar. In the studies on the statistical structure two statistical average molecular models were constructed. They are dimethyl phenylindene and dimethyl naphthalenol for non PC of 4th and 5th distilled fractions.
