The Thermochemistry of Some Organo- Phosphorus Compounds
After the combustions, the phosphoric acid was, in fact, in aqueous solution, so that a correction for the heat of solution was necessary. These combustions were made in a static bomb, and as a result the concentration of phosphoric acid probably varied considerably in different parts of the bomb, leading to the comparatively large error of ±O·l per cent, associated with the heats of combustion...

متن کاملOrgano-nitrogen Compounds from Molecular Nitrogen
INTRODUCTION Industrial nitrogen fixation plays an important role in sustaining approximately 40% of the Earth’s population through generation of synthetic fertilizers. Annually, ca. 500 million tons of anhydrous ammonia, ammonium nitrate, and urea are produced through the Haber-Bosch process, which requires harsh conditions (200 atm, 450-500C) and affords low yields 10-20%. It has been estimat...
متن کاملStudies on the delayed neurotoxicity of organophosphorus compounds- (I).
Delayed neurotoxicity experiments of an organophosphorus compound, TOCP, on hens and quails were carried out. The animals were orally exposed with TOCP in dose of 400 mg/kg, and maintained for 25 and 50 days under observation, respectively. They were sacrificed and dissected at different periods after the exposure, and the histopathological examinations were made on those animals. During the pe...
متن کاملStudies on heterocyclic compounds. I - Synthesis of some new 1,2,4-triazole derivatives.
In the present study, starting compound 4 was prepared by deamination of compound 2 in the presence of hypophosphorous acid and sodium nitrite. Treatment of compound 4 with ethyl bromoacetate produced ethyl[3-(4-chlorophenyl)-5-(4-methoxybenzyl)-4H-1,2,4-triazol-4-yl]acetate (5), which was converted to the hydrazide derivative (6) by treatment with hydrazine hydrate. The reaction of compound 6 ...
