The isobaric vapor-liquid equilibrium data of butanone(1)-N, N-dimethylformamide (DMF)(2) at 100.92kPa, 93.32kPa, and 79.99kPa and of toluene(1)-DMF(2) at 100.92kPa were measured using a modified Rose-Williams still. ...The isobaric vapor-liquid equilibrium data of butanone(1)-N, N-dimethylformamide (DMF)(2) at 100.92kPa, 93.32kPa, and 79.99kPa and of toluene(1)-DMF(2) at 100.92kPa were measured using a modified Rose-Williams still. The above data met the thermodynamic consistency test and were correlated with the Wilson,NRTL, and UNIQUAC equations. These data can be used in the analysis and design of the process that involves separating DMF from butanone and toluene in the leather synthesis industry.展开更多

The cyclic voltammetry, current time curve at potential step and potential time curve of galvanostatic method were used to investigate the electrochemical behavior of Er(Ⅲ) in ErCl 3 LiClO 4 DMF(N, N dimethylformamid...The cyclic voltammetry, current time curve at potential step and potential time curve of galvanostatic method were used to investigate the electrochemical behavior of Er(Ⅲ) in ErCl 3 LiClO 4 DMF(N, N dimethylformamide) system on Pt and Cu electrodes. Results indicate that the electroreducation of Er(Ⅲ) to Er(0) is irreversible on Pt and Cu electrodes, the diffusion coefficient and electron transfer coefficient of Er(Ⅲ) in 0.01 mol/L ErCl 3 0.1 mol/L LiClO 4 DMF system at 303 K are 1.96×10 -6 cm 2·s -1 and 0.081 respectively. The Er metal film was prepared by galvanostatic electrolysis on Cu electrode in ErCl 3 LiClO 4 DMF system at 40 A·m -2 (current density). The deposites composed of Er over 95%(mass fraction) were obtained.展开更多
