The direct densitometric determination of mono-, di-, and trisaccharides, methyl ethers and methyl-glycosides of sugars, sugar alcohols, and acids on paper and thin-layer chromatograms was studied. [ABSTRACT FROM AUTHOR]

A description is given of the qualitative determination of glyoxylic acid by paper chromatography in a mixture with some monosaccharides and organic acids. [ABSTRACT FROM AUTHOR]

The direct bromination of adenosine glucosyl diphosphate with bromine in dioxane was accomplished to give 8-bromoadenosine 5′-( α-D-glucopyranosyl diphosphate) in 63% yield. [ABSTRACT FROM AUTHOR]

The structure of clematoside C-an oleanolic acid decaoside isolated from the roots of Clematis manshurica-was established. [ABSTRACT FROM AUTHOR]

The decomposition of aspen lignin with sodium in liquid ammonia gave a mixture of phenols, of which dihydroeugenol, 1-(4-hydroxy-3-methoxyphenyl)-1- and -3-propanols, and 1-(4-hydroxy-3,5-dimethoxyphenyl)propane were identified by paper chromatography. [ABSTRACT FROM AUTHOR]

The synthesis of α-cellobiosyl phosphate was accomplished for the first time, and an improved method was developed for the synthesis of α-maltosyl phosphate by the fusion of the β-acetates of the corresponding disaccharides with HPO. [ABSTRACT FROM AUTHOR]

The condensation of cellulose dialdehyde with nitromethane proceeds in two directions; in harmony with this, two kinds of amino polyacetals can be obtained when the condensation products are reduced. [ABSTRACT FROM AUTHOR]

The partial structure of clematoside C - a glycoside of oleanolic acid containing ten monosaccharide residues - was established. [ABSTRACT FROM AUTHOR]

In a magnetic study of the coprecipitated NiO-AlO catalysts containing up to 59 mole % NiO, which had been subjected to a thermal treatment at 400‡, 600‡ and 750‡, the values of χ, Μ and δ were determined, and it was shown that: We established a good correlation of the magnetochemical data with the results of measurement of the activity [1] and of the roentgenographic determination of the structure [2]. It was shown that the extremal region in the graphs of magnetic properties - composition is the optimal one for the dehydrating activity of the catalysts. [ABSTRACT FROM AUTHOR]

When this paper was already prepared for publication, an article [8] appeared in which the preparation of some dialkyl diaryl orthotitanates by the partial transesterification of tetrabutyl orthotitanate is described. The products described, however, were not purified in any way. and the analytical results given for titanium are in good agreement also with an equimolecular mixture of the corresponding symmetrical alkyl orthotitanates. In the same paper the author refers to his preparation of 2-chloroethyl orthotitanate and benzyl orthotitanate, substances already described by its in 1951 [4]. [ABSTRACT FROM AUTHOR]
