Definitions
- the acid mixture employed usually consists of about five parts of sulphuric acid and three parts of nitric acid by weight.
- a quantity of the mixed acids, eight" times the weight of tetrol to be nitrated, is placed in a suitable reaction vessel which is immersed in ice. The tetrol is slowly added in portions to the acid mixture while agitating.
- tetrols employed in preparing the compounds of the present invention are prepared in accordance with the procedure described in our tanediol tetranitrate.

Description
Patented Aug. 7, 1945 UNITED STATES PATENT OFFICE ALIPHATIC DINITRO TETRANITRATES Henry B. Hass, West La Fayette, Ind., and Wilbur R. McElroy, Beacon, N. Y., assignors to Purdue Research Foundation, La Fayette, Ind., a corporation of Indiana No Drawing. Application July 29, 1944, Serial No. 547,285
4 Claims.
copending application, U. S. Serial No. 547,284, filed July 29, 1944. By the procedure there described, the desired dinitroalkane is reacted with formaldehyde in a ratio of four moles of the latter to one of dinitroalkane. The reaction is effected N02 No. 5 1n the presence of an alkallne catalyst such as 4 (CH2)n-CCH2ONO2 calcium hydroxide and a suitable solvent such as CHzONO, CEONO, ethanol. The temperature of the reaction mixture should preferably be held at about 20 C. 1n which n represents an integer less than 5. 10 In the table app g below some of the vari- As examples of compounds contemplated by the ous physical properties of certain aliphatic dinitro present invention, there may be mentioned 2,4- tetranitrates covered by the present invention are bis-(hydroxymethyl) -2,4-dinitro-1.5-pentanedio1 listed.

Generally the acid mixture employed usually consists of about five parts of sulphuric acid and three parts of nitric acid by weight. A quantity of the mixed acids, eight" times the weight of tetrol to be nitrated, is placed in a suitable reaction vessel which is immersed in ice. The tetrol is slowly added in portions to the acid mixture while agitating. After the entire amount of tetrol has been added in this manner, agitation is continued for a short time and there after the contents of the reaction vessel are poured into a large volume of ice water. The tetranitrate then separates as an insoluble product. Further purification of the material thus obtained may be effected by recrystallization from methanol or other suitable solvents.
The tetrols employed in preparing the compounds of the present invention are prepared in accordance with the procedure described in our tanediol tetranitrate.
While the above data may be of value'in the of these compounds will be apparent to those skilled in the art.
Our invention now having been described, what We claim is: 1 1. Aliphatic dinitro tetranitrates of the formu- 1T0: lTTOg O NOH2CC-(CHz)n-CCH2ONOz CHaONOz CHzONOz in which n represents an integer less than 5.
