The metabolism of 2:4-,2:5-and 3:4-dichloronitrobenzene in the rabbit.
an appreciable proportion of a dose of most of these compounds was converted into mercapturic acid in the rabbit. These mercapturic acids had been formed by a process resulting in the substitution of either a nitro or a chloro group by the acetylcysteyl group (acetylcysteyldenitration or acetylcysteyldechlorination) instead of replacement of a nuclear hydrogen as had been observed in all previo...
متن کاملCompilation of thermal properties of hydrogen in its various isotopic and ortho-para modifications.
New developments in science and industry are aided by accurate knowledge of the behavior of important substances. The great abundance of chemical processes and comX pounds in which hydrogen is involved make it of particular interest. The experimental and derived data presented here for hydrogen extend over a large range of temperature. Low temperatures are required for the liquid and solid, and...
متن کاملSeparating para and ortho water.
Water exists as two nuclear-spin isomers, para and ortho, determined by the overall spin of its two hydrogen nuclei. For isolated water molecules, the conversion between these isomers is forbidden and they act as different molecular species. Yet, these species are not readily separated, and no pure para sample has been produced. Accordingly, little is known about their specific physical and che...

An efficient synthesis of 3-substituted or 2,3-disubstituted 4(3H)-quinazolinones from benzoxazin-4-ones and primary amines under microwave irradiation in unsealed vessels is described.
متن کاملEquilibrium Constants of the Complexation of Molybdate Ion with para-Sulfonatocalix [4] arene in aqueous media
The complexation of sodium molybdate with para-sulfonatocalix [4] arene was studied in thetemperature range from 20 to 40 °C and pH = 5.8 by spectroscopic method in water solution. Thestability constants of complexes were calculated by the multiwavelength analysis of spectral datausing SQUAD program. The equilibrium constant, spectroscopic data, molar absorptivities andconcentrations of all spe...
