General experimental procedure, methods of analysis, and purification of materials have been given sufficiently in detail in order that the sources of difficulty and uncertainty in the results obtained not only in this paper but also in this series of investigations on the non-catalytic synthesis of hydrocarbon liquids directly from calcium carbide may be estimated.
Orientation and exploratory investigations have been made on hydrogen systems, and it has been found that a grain size of 1 to 2 mm, a saturation temperature of 80°C, and a reaction temperature of 340°C proved most suitable for the synthesis of liquid hydrocarbons under our experimental conditions.
The effects on the formations of the products of temperature have been discussed. These effects are intimately associated with the heat of reaction involving the carbide which is large.
The effects of the time of contact and of the grain size have been briefly mentioned in passing.
