摘要

对第二维里系数与温度的经验关联式作了评选

推荐B=B_0+B_1/t+B_2/t~2+B_3/t~3+B_4/t~4

t=T/1000

和lg(-B)=E_0+E_1(100/T)+E_2lg(T/100)

对166种纯物质作了关联.利用上述物质的第二维里系数数据推算其Lennard-Jones位能参数值和41种极性物质的Stockmayer位能参数值.

Abstract

The mathematical expressions for correlating the second virial coefficients for 166 pure substances with temperature are reviewed and selected. B = Be + B1/t + B2/t2 + B3/t3 + B4/t4

t=T/1000

and lg(-B)=E0 +E1(100/T) + E2lg(T/100) are recommended. Using the second virial coefficient data

Lennard-Jones parameters for the above-mentioned substances and Stockmayer parameters for 41 polar compounds are determined.
