Preparation and properties of carbamates, nitrocarbamates and their derivatives
Since representative alipahtic N-Nitrocarbamates have been found by Dr. J. Philip Mason and Mr. Robert T. Pollock to be suitable additives for Diesel fuels, it was thought desirable to synthesize several members of the series not recorded in the literature. Accordingly plans were made for the …
