Isobaric vapour–liquid equilibria of Binary 1-propoxy-2-propanol mixtures with water and alcohols at reduced pressure
Fluid Phase Equilibria, 2020Co-Authors: B. Ramsauer, R. Neueder, W. KunzAbstract:A dynamic recirculation app. has been used to det. the isobaric phase equil. of Binary 1-propoxy-2-propanol (PnP) mixts. with water and different alcs. (methanol, ethanol, 2-butanol and 1-hexanol). The systems exhibit both pos. and neg. deviations from Raoult's law. No azeotropic mixt. is found in any of the systems under investigation. The Binary Diagram of water/PnP shows the well-known liq.-liq.-sepn. The exptl. results are correlated with the Wilson, NRTL and UNIQUAC model and also compared to the COSMO-RS predictive model and the modified UNIFAC group-contribution method. Addnl., the vapor pressure of PnP has been detd. exptl. up to 140 ° C as prerequisite for modeling of the data

Isobaric vapour–liquid equilibria of Binary 1-propoxy-2-propanol mixtures with water and alcohols at reduced pressure
Fluid Phase Equilibria, 2008Co-Authors: B. Ramsauer, R. Neueder, W. KunzAbstract:Abstract A dynamic recirculation apparatus has been used to determine the isobaric phase equilibria of Binary 1-propoxy-2-propanol mixtures with water and different alcohols (methanol, ethanol, 2-butanol and 1-hexanol). The systems exhibit both positive and negative deviations from Raoult’s law. No azeotropic mixture is found in any of the systems under investigation. The Binary Diagram of water/1-propoxy-2-propanol (PnP) shows the well-known liquid–liquid-separation. The experimental results are correlated with the Wilson, NRTL and UNIQUAC model and also compared to the COSMO-RS predictive model and the modified UNIFAC group-contribution method. Additionally, the vapour pressure of PnP has been determined experimentally up to 140 ° C as prerequisite for modelling of the data.

Cu-Cr contact materials for high power vacuum interrupters
The Chinese Journal of Nonferrous Metals, 2020Co-Authors: Xian Ai-pingAbstract:The recent development of Cu Cr contact materials for high power vacuum interrupters is concluded. It includes the origination of Cu Cr alloy and technical advantages; the characteristic of Cu Cr Binary Diagram and the difficulties in convenient casting process; the main preparation processes of Cu Cr alloy, such as powder sinter, sinter and vacuum infiltrate and arc melting process; the influence of impurities, such as residual gases, residual carbon and the third element in Cu Cr alloy, on the properties of Cu Cr alloy etc. Also, it summarizes the effect of Cu Cr alloy and its microstructure on the basic electrical properties of the vacuum contactor (such as circuit interruption ability, resistance to erosion by arc, current chop etc.). Finally, the developing direction of the Cu Cr contact materials in the future (Cr particle dispersion, alloy recycle and qui fast solidification process, and spray forming etc.) are also discussed.
