the amount percent of alkanes, aromatic hydrocarbon, cycloalkane and chlohydrocarbon reaches 56.1%, which are the most prevalent compounds in indoors air of hangzhou.
in addition, the activity mechanism of phenylsulfonyl cycloalkane carboxylates was also investigated based on the relevant qsar models.
根据所得qsar模型对苯砜基羧酸酯类化合物的的活性机理进行探讨。
the hydrogenation saturation of aromatics and selective ring opening of cycloalkane were the most important process during deep dearomatization of diesel oil.
单环芳烃的加氢饱和与环烷烃的选择开环是柴油深度脱芳过程中的重要反应。
and cycloalkane without substitute group is hard to be attacked by microorganism, therefore could exist for a long time, abiding and destroying the environment seriously.
