摘要
应用Fuzzy多层次评判理论,建立因变量为选择性和溶解性,自变量分别为腐蚀性、比热容、粘性、沸点和毒性的隶属函数。给出了各自变量的权重比例,构建了Fuzzy多层次综合评价模型,并针对苯和庚烷的六种萃取溶剂进行综合评价。结果表明:糠醛无论在选择性还是在溶解性方面与其它溶剂相比均为最佳选择试剂。
The fuzzy multilevel judgement theory was used to establish the subordinate function,whose dependent variables were selectivity and dissolubility and independent variables were corrosivity,specific heat,molecular weight,viscosity,boiling point and poisonousness.Through giving weight proportion of every independent variables,the fuzzy multilevel judgement model was built.Then six extractants for extracting benzene and heptane were comprehensivly evaluated.The results indicate that compared with the other extractants,furfural is the best extractant in terms of selectivity and dissolubility
