| Abstract: | Solid liquid equilibrium data of maleic anhydride in diethyl adipate,diethyl malonate,diethyl succinate,diethyl sebacate were experimentally determined by means of polythermal method,and experimental data were compared with solubility data of maleic anhydride in 1,2 cyclohexanedicarboxylic acid diisobutyl ester.Chain dicarboxylic acid diesters are suitable for recovering maleic anhydride.Experienced equation,λ H equation and Wilson equation were used to correlate data.Wilson equation can correlate the solubility data well. |
