摘要
通过模拟实验发现硫能和各种链状化合物反应形成噻吩系列化合物。其反应机理可能是： 硫先作用于链状化合物将其改造成共轭烯中间体， 其他硫再从这个部位进入碳骨架从而形成该类化合物。硫还可进一步和噻吩系列反应形成更复杂的含硫芳烃，而温度升高会促进这种反应，所以噻吩系列的含量可以作为成熟度指标，在沉积条件相同的前提下，噻吩系列含量高指示成熟度低，反之则指示成熟度高。
Through the simulation experiment it is concluded that sulphur can react with different kinds of chain compounds to form thiophene series compounds. The reaction mechanism is probably that sulphur acts on the chain compounds and makes them to become the conjugate alkene intermediate at first, then the other sulphur attacks the intermediate and joins the carbon skeleton to form thiophene series. Sulphur may furtherly react with thiophene series to form the aromatic hydrocarbons containning sulphur with more complex structure, and the reaction is promoted with the increasing of temperature. So the content of thiophene series can indicate the maturity of organic matter under the condition of same sedimental environment, high content of the thiophene series indicates low maturity, and low content indicates high maturity.
