[BMim][HSO4]/H2SO4二元体系的黏度及其表面张力
Viscosity and surface tensions of [BMim] [HSO4]/H2SO4 binary system
摘要
Abstract
At the range of 293.2-313.2 K,the viscosities and surface tensions of 1-butyl-3-methylimidazolium hydrogen sulfate([BMim] [HSO4])/H2SO4 binary system were measured and calculated by Jouyban-Acree(JAM) and Li-Wang(LWW) equation respectively.The excess viscosities and excess surface tensions of the binary system were fitted by Redlich-Kister(R-K) and Myers-Scott(MS) equation separately.The results show that the viscosities of[BMim] [HSO4]/H2SO4 decreased with the increasing temperature and increased with the increasing molar fraction of [BMim] [HSO4] (xIL).The excess viscosities of the binary system are negative and reach minimum at xIL ≈ 0.75.The surface tensions of the binary system decrease slightly with increasing temperature and xIL.The surface tensions of the binary system are negative and reach minimum at xIL ≈ 0.1.The viscosities and surface tensions of the binary system are fitted well by JAM and LWW equation.The relative standard deviations are no more than 8.74% and 0.16%,respectively.R-K and MS equation describes the excess viscosities and excess surface tensions of the binary system well,both of their correlation coefficient R2 are not less than 0.99 and 0.97 separately.关键词
