Acute, 9-day, and 13-week vapor inhalation studies on ethylene glycol monohexyl ether At ambient conditions, the low vapor pressure of ethylene glycol monohexyl ether (EGHE) allows for a maximum vapor concentration of approximately 85 ppm. I... DR Klonne,DE Dodd,IM Pritts,... - 《Fundam...
In an absorption refrigeration system, the absorbent is an aqueous saline solution having therein a vapour pressure depressant which is ethylene (or diethylene) glycol monobutyl ether. The depressant is preferably provided in the range of 0001 to 10 weight per cent based on total solution and the...
What is the heat of vapourization if the vapour pressure of liquid water at 25 degree C is 23.8 torr and at a boiling point of 100 degree C is 760 torr ? At 35C water has a vapor pressure of 42.2 torr. What is the partial pressur...
Additionally, between the steel sheet metal and the laminate, a liquid-filled bag was placed, which was a mixture of ethylene glycol (C2H6O2) with 5... I Cibulka,J Fontaine,K Sosnkowska-Kehiaian,... 被引量: 0发表: 2012年 High-pressure phase equilibria and thermodynamic modelling for the...
2.Vapor-Liquid Equilibria data in vacuum (under the pressure of 50 mmHg and 100 mmHg) have been obtained for toluenedi- amine (TDA) isomeric compounds using a recirculation still.将该模型用于TDA同分异构体分离塔的模拟计算中,结果与生产数据基本相吻合,表明所得的TDA同分异构体的气液平衡关系以及由...
and evaporates water from the milk. The vapor is separated from the concentrated milk and is used for evaporation at a lower pressure in the next stage. Using multiple-stage evaporators allows multiple reuse of vapor and saves large quantities of energy (Kessler, 1981; Ramírez et al., 2006...
In both cases, an excellent stability of the layer and its wetting behavior was found with N2 plasma/glycerin. Ref. [38] reported the surface modification of poly(vinylidene fluoride) (PVDF) membrane with poly(ethylene glycol) diacrylate (PEGDA) via a low-pressure plasma-induced plasma source ...
Vapor–liquid equilibrium (VLE) data of iso-propanol+iso-butanol and iso-propanol+iso-butanol+CaCl2 (at saturation) were measured at a pressure of 93.6 kPa, using a modified Malanowski equilibrium still. The VLE behavior of the salt-free system is nearly ideal with a maximum normalized excess...
