Abstract
The thermal decomposition reaction of acetone by addition of a small amoumt of carbon disulfide and the order of reaction for thermal decomposition reaction of ketene thus formed have been investigated in detail. Also, the thermal decomposition reaction of acetone was carried out in the current of nitrogen in order to increase the yield of ketene. The result indicated that the rate of formation of ethylene, ethane, as well as ketene was increased than in the case of addition of no nitrogen and this indicated that the decomposition reaction of ketene was effected by the dilution with nitrogen. Further thermodynamical investigations on the thermal decomposition reaction of acetone and ketene have been made and it was confirmed that the thermal decomposition reaction of acetone was the first order reaction and the experimental results can be explained well by supposing the thermal decomposition reaction of ketene is 1.5th order.
