At low temperature , the lithium ( potassium ) reagent is made from substituted aromatics . Then , this reagent reacts with hexachloroethane to obtain chlorinated aromatic hydrocarbons with high conversion rate .
将取代芳烃在低温下制成锂（钾）试剂，再与六氯乙烷反应，可以得到较高转化率的氯代芳烃。
The oxidation coupling of methane , the partial oxidation of methane to syngas , and the conversion of methane to hydrogen and aromatics are very important academically and economically , for these routes providing ways to produce liquid fuel from natural gas rather than those from petroleum .
Long chain alkyl benzenes is the product of cyclization-decarboxylation-aromatization of fatty acid , with the help of clay minerals catalytic effect , which comes from bacteria , seaseed and higher plant lipid ; or the reaction product of monocylic aromatics and fatty acid alkyl group under the same conditions .
