一般描述

苯广泛用作溶剂。热带生物物种所释放的苯量已经过调查。GC/MS 测定表明:苯是生物质燃烧排放因子的主要促成物之一。采用 CNDO 方法研究了它的电子光谱。研究了苯与水(H 2 O、D 2 O 和 HDO)的同位素1:1 簇的微波光谱。

应用

通过在约 1100°C下与氢热解,可在碳纤维的制备过程中使用苯。它被用于高导电性分子结的制备。这些结是通过在不使用参照组的情况下将苯分子直接结合到铂电极制成的。

Microbial electrochemical technologies (MET) are increasingly being considered for in situ remediation of contaminated groundwater. However, their application potential for the simultaneous treatment of complex mixtures of organic and inorganic contaminants, has been only marginally explored. Here we have analyzed
