The Use of Reaction Calorimetric Methods for Measuring Heats of Formation of Organo-metallic Compounds
The measurement of the heats of formation of organo-metallic compounds presents, usually, a difficult task to the experimental thermochemist. Thus the method of combustion in a conventional bomb-calorimeter, although it has been applied to a number of metallic alkyls in recent years! and yielded valuable results, is nevertheless not entirely satisfactory. The difficulty is that complete oxidati...
متن کاملThe 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...
