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. This error could be reduced very considerably by using a rotating bomb technique. A number of organo-phosphorus compounds undergo reactions which can be studied conveniently in a simple reaction calorimeter. An example
