摘　　要：Thermal analysis was employed to investigate the desorption temperatures(Td) of alcohols on the surface of α-Al2O3 and silicion gel in this paper.The quantative relationship between Td and boiling point(Tb),polarizability effect index(PEI)was:Td(℃)=2111+06185Tb(℃)-22868PEI (on α-Al2O3) with a correlation coefficient of 09986 and a standard deviation of 13246,Td(℃)=50585+04673Tb(℃)-29195PEI (on silica gel) with a correlation coefficient of 09937 and a standard deviation of 21877.Thermal analysis was employed to investigate the desorption temperatures(Td) of alcohols on the surface of α-Al2O3 and silicion gel in this paper.The quantative relationship between Td and boiling point(Tb),polarizability effect index(PEI)was:Td(℃)=2111+06185Tb(℃)-22868PEI (on α-Al2O3) with a correlation coefficient of 09986 and a standard deviation of 13246,Td(℃)=50585+04673Tb(℃)-29195PEI (on silica gel) with a correlation coefficient of 09937 and a standard deviation of 21877.
