The crystal structure of ammonium tris[4,4,4-trifluoro-1-(2-furyl)1,3-butanedione]cadmium(II), NH 4 [Cd(C 8 H 4 O 3 F 3 ) 3 ], has been determined using 655 visually estimated reflection intensities. Full matrix least squares refinement led to R = 0.

The rate of reaction of Ni(II) ion and acetylacetone to form monoacetylacetonate nickel(II) ion was studied conductometrically by a stop-flow method. The solvents consisted of several mixtures of water in 2-propanol ranging from 9·85 to 14·45 per c

It is often assumed that the n-heptane chromatographic fraction represents the total saturated hydrocarbon content of asphaltic matter. This assumption, however, is based on an approximation rather than on an analytically rigorous finding. C14-labell
