选取最高占据轨道能量E_(HOMO)、最低空轨道能量E_(LUMO)、分子体积V_m、分配系数ClgP、偶极距μ及二阶分子连接性指数~2X作为烃基黄药类捕收剂的结构性参数,通过回归分析,建立了烃基黄药类捕收剂的定量结构-生物降解性能关系模型(QSBR),并进行了预测。结果表明,E_(LUMO)、~2X(即分子最低空轨道能量水平和二阶分子连接性指数)对烃基黄药类捕收剂的生物降解性能有显著影响。

The article intends to make a study of the biodegradability and its correlation with its quantitative structure of the alkyl xanthates flotation collectors in hoping to learn to control and prevent the pollution of the agents as well as to provide a theory for the synthesis and application of the flotation agents.It is for the said purpose,we have chosen five kinds of alkyl xanthates flotation collectors as research goal with the method of shaking the cultivated solution of the aerobic biodegradability of ethyl xanthate,the isopropyl xanthate,n...
