Water gel explosives have been used in the mining industry due to their ease and safety in handling. The prime ingredient is monomethylamine nitrate made from MMA, formaldehyde, and ammonium nitrate. Perchlorates of mono-, di-, and trimethylamine have also been used in the mining industry.
There have been some military uses for 2, 4, 6- trinitrophenylmethyl nitramine made from the nitration of dinitromethylaniline with nitric acid. Dinitromethylaniline is the product of MMA plus dinitrochlorobenzene in the presence of caustic. Fuses have been made from trimethylamine with nitric acid and nitrous perchlorate-paraffin mixtures.
