MANY mixtures of volatile anaesthetics have been -used in the past with some success, but they are difficult to handle in the modern anaesthetic apparatus. Because of the differences in the boiling points of the components of these mixtures, they volatilize at different rates and therefore it is almost impossible to know their concentration in the anaesthetic mixture administered to the patient...

The paper presents a study on the performance of conventional plant-producing ethyl acetate from ethanol and acetic acid. Process models were compiled in simulator Chemcad 7. impact key parameters individual installation nodes was examined by sensitivity analysis. Three approaches are presented compared: two classic with different heat duties an improved one. An technological solution, closed c...

This paper addresses the internal heat integration to the pressure-swing distillation process used in the separation of binary azeotrope mixture. A general procedure is suggested and illustrated through the separation of an binary mixture, which forms pressure-sensitive minimum-boiling azeotropes. Comparisons are made between the conventional and the internally heat integration processes. It is...

Free energies and correlation functions of liquid and solid hard-sphere (HS) mixtures are calculated using the fundamental measure density functional theory. Using the thermodynamic perturbation theory the free energies of solid and liquid Lennard-Jones (LJ) mixtures are obtained from correlation functions of HS systems within a single theoretical approach. The resulting azeotrope- and spindle-...

U ranium tetraethoxy monobenzoate (1.251 g.) was taken in benzene (55 g .). To this tertiary butanol (0.65 g.) was added. The reaction m ixture was refluxed for seven hours. D uring this period benzene ethanol azeotrope was collected slowly. Followed by a few ml of pure benzene at 80 °C. On drying under reduced pressure as above a reddish brown viscous liquid (1.47 g.) sparingly soluble in benz...

2014 We investigate the stability of the planar front during directional solidification of a quasi-azeotrope. We show that the corresponding shape of the phase diagram induces a strong reduction of the scale of the bifurcation curve which makes its complete exploration feasible in standard directional solidification experiments. We show that the finite concentration of azeotropic mixtures resul...

Fermentation flavors of corn distillers' grains (CDG) were removed more completely by extraction with hexane:ethanol (82:18 v/v) azeotrope (HEA) than with hexane (H). Desolventizing included air drying followed by heating to 101°C for 10 min with agitated steam injection. Enriched corn-soy-milk (CSM) blends were formulated with up to 10% REAor H-extracted CDG. Color was slightly darker in CSM w...

Blood anesthetic concentration and clinical indicators related to anesthetic management during surface-induced deep hypothermia were determined in seven adult mongrel dogs. The azeotrope of halothane and diethyl ether was assayed by gas chromatography. Blood concentration of halothane ranged from a pre-cooling control of 0.74 vol % to 0.11 vol % at 20 degrees C rewarming; ether ranged from 0.06...
