The completely substituted product is a white, granular, solid with mw 246 30 and mp 240—45° Its method of prepn was described by Hess Muller (Ref 1). The triethylcellu lose is insol in w and practically insol in methanol, etbanol acetone, but sol in dilf, pyridine, ethylene dichloride, ethyl acetate, carbon tetrachloride and many other organic solvents. This product has, however, no military or commercial application because it lacks strengths flexibility, is not thermoplastic and shows only very limited compatibility...

The importance of selecting gravimetry instead of volumetry to measure liquid amounts in the pharmaceutical industry of liquid dosage forms is well illustrated by the volume contraction of water-ethanol and volume expansion of ethyl acetate-carbon disulfide liquid mixtures as well as a CS2-ethyl acetate system. The National Formulary (NF) diluted alcohol is a typical example of the volume nonadditivity of liquid mixtures [29], This solution is prepared by mixing equal volumes of alcohol [U.S. Pharmacopeia (USP)] USP and purified water (USP). The final volume of this solution is about 3% less than the sum of the individual volumes because of the contraction due to the mixing phenomenon [1], In addition, molecular interactions of surfactants in mixed monolayers at the air-aqueous solution interface and in mixed micelles in aqueous media also cause some contraction of volume upon mixing [30],...

Pentaethoxyuranium is a dark-brown, mobile liquid with a density of 1.71 g/cm3 at 25°.2 The liquid boils at 123° at 0.001 torr and is thermally stable below 170°. The compound is readily hydrolyzed and is oxidized by dry oxygen (in the presence of excess NaOC2Hs) to hexaethoxyuranium.2 Pentaethoxyuranium has a dimeric structure at room temperature as determined by freezing-point depression measurements in benzene.2 It is miscible with ethanol, diethyl ether, benzene, petroleum ether, ethyl acetate, carbon tetrachloride, chloroform, carbon disulfide, pyridine, dioxane, and nitrobenzene. The proton magnetic...

The various teams [19, 125, 128, 135, 191, 245, 256, 290, 319] have used mostly aqueous-alcoholic mobile phases hke, for example, chloro-form-methanol-water (65 + 35 -f 10) for separation of mixtures of neutral triterpene glycosides. The ethyl acetate-carbon tetrachloride mixtures which Linde [150] has employed for separation of Cimicifuga glycosides, are less polar (cf. also [35, 36]).
