摘要:

AbstractThe variation of vapor pressure and density with temperature up to the normal boiling point has been obtained for 32 homopolar liquids. From these measurements, the latent heats at the boiling point and the normal and true lyoparachors have been calculated. In keeping withBowden and Jones'sfindings, the lyoparachors were found to be additive properties determined by the composition and molecular constitution of the compound. New bond and atom constants for the lyoparachors have been obtained.

摘要:

AbstractWhereas benzoylation of toluene orm‐xylene is known to lead to a mixture of 2‐ and 4‐methylbenzophenone and to 2,4‐dimethylbenzophenone respectively, the presence of a blocking t.butyl group in the 4‐ and the 5‐positions respectively leads to products which on debutylation yield benzophenones with substituents in theorthopo

摘要:

AbstractThe preparation and the biological properties of a number of compounds with fungicidal, insecticidal and acaricidal activities are described. The compounds were prepared by substitution of a phosphorus containing group for a hydrogen atom of the 1,2,4‐triazole nucleus in 3‐amino‐1,2,4‐triazole or a 5‐ substituted derivative thereof.Biological activity was highest when the phosphorus containing group was a bis(dimethylamido)phospho

摘要:

AbstractThe effect of chelating substances on the orientation of hydroxymethyl groups in the reaction of phenol with formaldehyde is described.It is found that when using hydroxides of the transition metals, Cu, Cr, Mn, Ni and Co, in aequous solution at pH = 4‐5, hydroxymethylation occurs mainly at theortho‐position.Similar results were obtained with boric acid in benzene solution.Chelate formation in the transition state forortho‐substitution is supposed to be the basic reason for the selective cata
