摘要/Abstract

摘要： 基于44种二元含醚类物质混合溶液的运动黏度实验数据,采用ASOG-VISCO黏度模型回归得到了新的基团对O-CH₂,O-CyCH,O-ArCH,O-OH,O-COO,O-CCl₃,O-CCl₄的交互作用参数,所研究溶液体系为醚类与正烷烃、异烷烃、环烷烃、芳香族、醇类、氯仿、四氯化碳和酯类的混合物,黏度计算值与实验值的绝对平均偏差为3.31%。同时,为了验证回归得到的新交互作用参数对醚类混合溶液黏度预测的通用性,对11种其他醚类混合溶液的黏度进行了推算,计算值与实验值的绝对平均偏差为5.95%,可以满足实际工程需要。

Abstract: In this work,new ASOG-VISCO group pair parameters of O-CH₂,O-CyCH,O-ArCH,O-OH,O-COO,O-CCl₃,and O-CCl₄ are determined based on the experimental kinematic viscosities of 44 binary mixtures containing ethers reported in literature.The ASOG-VISCO method and the new parameters obtained are applied to predict kinematic viscosities for these binary liquid mixtures,including associative mixtures of linear,branched,cyclic,aromatic hydrocarbons,ethers,alcohols,chloroform,carbon tetrachloride and esters.The absolute average deviation between calculated and experimental values is 3.31%.The ASOG-VISCO model and these interaction parameters are also applied to calculate kinematic viscosities for binary mixtures containing polyethers,and the absolute average deviation between calculated and experimental values is 5.95%.

Key words: ASOG-VISCO model, ether mixture, kinematic viscosity
