The densities and refractive indices (Nc) of binary and ternary mixtures of benzene, ethyl alcohol, and carbon tetrachloride have been determined at 25 °C. From these data, a method for the analysis of ternary liquid mixtures of these components has been developed. The limit of accuracy in the analysis of ternary mixtures of the pure components is 0.3%. The method can be applied to the analysis of commercial materials with an accuracy of 2.0%.


In two recent papers from these laboratories it was shown that when methane- and ethane-oxygen mixtures containing excess of the hydrocarbon react at high pressure various liquid products can be isolated. For methane-oxygen mixtures methyl alcohol and water are found, and for ethane-oxygen mixtures ethyl alcohol, acetaldehyde, methyl alcohol, acetic acid, formic acid, and water. These products being important for the light they throw on the mechanism of hydrocarbon combustion and because they suggest means for using waste hydrocarbon gases, further experiments have now been made with the object of finding the order of their formation and the optimum condition for their survival.

Treatment of methyl 4,6-O-benzylidene-3-deoxy-3-nitro-β-D-glucopyranoside (1) and its α-anomer (3), as well as of methyl 4,6-O-benzylidene-2,3-dideoxy-3-nitro-β-D-erythro-hex-2-enopyranoside (2) and its α-anomer (4), with basic aluminum oxide in refluxing toluene, leads to loss of the nitro and glycosidic methoxyl groups. As a common product an α,β-unsaturated lactone, 4,6-O-benzylidene-2,3-dideoxy-D-erythro-hex-2-enono-1,5-lactone (5), was isolated in crystalline form. The β-D-manno isomer (6) of 1 incurs epimerization to 1 and partial conversion to 5. Methyl 4,6-O-benzylidene-3-deoxy-3-nitro-β-D-galacto-pyranoside (7) and methyl 4,6-O-benzylidene-2,3-dideoxy-3-nitro-β-D-threo-hex-2-enopyranoside (8) similarly yield a crystalline lactone, 4,6-O-benzylidene-2,3-dideoxy-D-threo-hex-2-enono-1,5-lactone (9). The mechanism of this novel reaction is discussed, and certain differences in reactivity in the gluco and galacto series are pointed out. Base-catalyzed additions of methyl alcohol, ethyl alcohol, and piperidine to 8 afford methyl 4,6-O-benzylidene-3-deoxy-2-O-methyl-3-nitro-β-D-galactopyranoside (10), its 2-O-ethyl analogue (11), and methyl 4,6-O-benzylidene-2,3-dideoxy-3-nitro-2-piperidino-β-D-galacto-pyranoside (12), respectively.
