Nitrations with dinitrogen pentoxide

Nitrations with dinitrogen pentoxide are conducted with two types of reagent  [Pg.350]

NITRATION WITH DINITROGEN PENTOXIDE 4.3.1 The State of dinitrogen pentoxide in various solvents... [Pg.51]

Nitration with dinitrogen pentoxide (N205) has increased in its importance as an environmentally cleaner alternative to conventional procedures. It might become the nitration method of the future. Dinitrogen pentoxide can be produced either by ozone oxidation of dinitrogen tetraoxide (N204) or electrolysis of N204 dissolved in nitric acid.19... [Pg.5]

The polymers 1, 3 and 4 were 0-nitrated with nitric acid to give products containing nitrogen contents of 11.6 %, 19.9 % and 9.55 % respectively. Polymer 2, on the other hand, was nitrated with dinitrogen pentoxide in liquid carbon dioxide. Evaluations of these energetic polymers indicate that polymer 1 is a possible candidate for use in insensitive munitions. [Pg.117]

The reaction of dinitrogen pentoxide with primary aliphatic nitramines and amines leads to deamination and the formation of a nitrate ester as the major product. Consequently, dinitrogen pentoxide cannot be used for the synthesis of primary nitramines. In contrast, both primary and secondary arylamines undergo efficient A-nitration with dinitrogen pentoxide in chlorinated solvents. ... [Pg.204]

The complex formed between dinitrogen pentoxide and boron Uifluoride is a powerful nitrating agent and has been used in organic solvents like carbon tetrachloride, nitromethane and sulfolane for the nitration of deactivated aromatic substrates, including the conversion of benzoic acid to 1,3-dinitrobenzoic acid in 70% yield. Olah and co-workers" studied aromatic nitrations with dinitrogen pentoxide in the presence of other Lewis acids. [Pg.355]

Nitrations with dinitrogen pentoxide in the presence of phosphorous pentoxide enable the complete utilization of available nitrogen. ... [Pg.355]

Nitration of diphenyl-2-carboxylic acid with concentrated nitric acid at room temperature gives a 79 2T mixture of 2 -nitrodiphenyl-2-carboxylic acid (2) and 4 -nitrodiphenyl-2-carboxylic acid (3). However, nitration with dinitrogen pentoxide in carbon tetrachloride at 0°(30 niin.) gave (2) in good yieid as the sole product. ... [Pg.895]
