Description

United States Patent O 3,002,022 v-TRINITROBUTYRAMIDE Robert H. Saunders, West Chester, Pa., assignor, by mesne assignments, to the United States of America as represented by the Secretary of the Navy No Drawing. Filed Feb. 28, 1952, Ser. No. 274,071 1 Claim. (Cl. 260-561) This invention relates to a new explosive compound, 'y-trinitrobutyramide.
The new compound of the invention is a white crystalline substance which is stable at room temperature. It has properties making its use as an explosive highly feasible, having an oxygen balance within permissible limits and an impact sensitivity in the range of that of tetryl.
The new compound may be prepared by the addition of nitroform across the double bond of acrylamide. The reaction is carried out by adding a slight excess of nitroform to acrylamide and heating at about 55 centigrade for a short time. The product formed is then recovered through crystallization by strong cooling with a Dry Ice bath.
It is an object of the invention to provide a new explosive compound, 'y-trinitrobutyramide.
The invention is illustrated by the following example, but it is not limited thereto:
Example.To 142 milligrams of acrylamide was added a slight excess of nitroform in 2 milliliters of methanol.
Patented Sept. 26, 1961 The mixture formed was heated at 55 C. for about 20 minutes. The resulting mixture was diluted with 3 milliliters of water and the product recovered by crystallization accomplished by strong cooling in a dry ice bath.
The percentage composition calculated for C4H6N3O7 is, 21.6 percent carbon, 2.7 percent hydrogen, 25.2 percent nitrogen and the remainder oxygen. Analysis of the compound gave, 21.7 precent carbon, 2.8 percent hydrogen and 24.4 percent nitrogen. It has an oxygen balance of 29. Its melting point is 92 C. The compound has an impact sensitivity of 56 as determined with the Bureau of Mines impact machine, this figure being the distance in centimeters a 2 kilogram weight was required to fall in order to produce shots. Its igni- No references cited.
