USE OF ISOTOPIC ANALYSIS FOR DETERMINATION OF AROMATIC HYDROCARBONS PRODUCED FROM METHANE

摘要

Benzene and xylene are described having a unique distribution of deuterium and ¹³C such that d(deuterium) for each of the benzene and xylene is less than -250 and d(^l3C) for the benzene is greater than -36 and for xylene is less than -24, wherein d(deuterium) = (R'_sample/R'_standard -1) X 1000 where R'_sample is the ratio of deuterium to hydrogen in the benzene/xylene; and R'_standard is the ratio of the natural abundance of deuterium to the natural abundance of hydrogen; and wherein d(¹³C) = (R"_sample/R"_standard - 1) X 1000 where R"_sample is the ratio of ¹³C to ¹²C in the benzene/xylene; and R"_standard, is the ratio of the natural abundance of ¹³C to the natural abundance of¹²C.
