Interesting phenomena are observed in the reduction of nitroform (trinitromethane) at the dropping mercury electrode [29]. On polarograms in unbuffered aqueous solutions the first wave corresponds to one-step reduction of the undissociated (N02>3CH molecule, and the second and subsequent waves correspond to multistep reduction of its anion (N02)3C". Accordingly the polarograms for an unbuffered solution of the potassium salt of nitroform (nitroform is a strong acid with pK =0.15) only contain the multistep wave for the reduction of the anion (Curve 1, Fig. 3), and this remains practically...

Grakauskas, V. et al., J. Org. Chem., 1978, 43, 3485-3488 Trinitromethane ( nitroform ), dinitroacetonitrile, their salts and polynitroalkanes are all potentially dangerous, and must be carefully handled as explosive compounds [1], Many congeners and derivatives of dinitromethane are explosive and require careful and appropriate handling [2], Individually indexed compounds are ... 

The reaction of alkynes with nitric acid or mixed acid is generally not synthetically useful. An exception is the reaction of acetylene with mixed acid or fuming nitric acid which leads to the formation of tetranitromethane. A modification to this reaction uses a mixture of anhydrous nitric acid and mercuric nitrate to form trinitromethane (nitroform) from acetylene. Nitroform is produced industrially via this method in a continuous process in 74 % yield. " The reaction of ethylene with 95-100 % nitric acid is also reported to yield nitroform (and 2-nitroethanol). The nitration of ketene with fuming nitric acid is reported to yield tetranitromethane. Tetranitromethane is conveniently synthesized in the laboratory by leaving a mixture of fuming nitric acid and acetic anhydride to stand at room temperature for several days. ... 

Delft University of Technology and the University of Delaware) is hydrazinium nitroformate [N2H5.C (N02)3 Structure (4.2)] a salt of hydrazine (N2H4) and nitro-form or trinitromethane [HC(N02)3], reported to have been discovered in 1951. Of course, this is made without the use of N205. It is prepared as a precipitate [74] by acid-base reaction between nitroform and hydrazine, Equation 4.18. 

Phenyldiazonium mtroformate. Nitroform derivative (XIII) is of particular interest among derivative diazonium salts. It was prepared by Ponzio [21] who reacted the potassium salt of trinitromethane (nitroform) with an aqueous solution of phenyldiazonium acetate ...

Hanizsch and Kinkenberger (171] established that TNM can quantitativel> be hydrolysed to trinitromethane by potassium hydroxide or potassium eih oxide. However, aqueous concentrated KOli can produce a deeper hydrolysis with the formation of KNO3, KNOi and K2CO3 (172]. The reaction of tlu formation of trinitromethane ( nitroform ) from TNM became a standar. method of making nitrotonn used for thesis of polynit ro aliphatic com pounds.
