Formic acid Nickel-aluminum

NITROCARBOL (75-52-5) Forms explosive mixture with air (flash point 95°F/35°C). Thermally unstable. Shock, friction, pressure, or elevated temperature above 599°F/315°C can cause explosive decomposition, especially if confined. Violent reaction with strong oxidizers, alkyl metal halides, diethylaluminum bromide, formic acid, methylzinc iodide. Contact with acids, bases, acetone, aluminum powder, amines, bis(2-aminoethyl)amine, haolforms make this material more sensitive to explosion. Reacts, possibly violently, with ammonium hydroxide, calcium hydroxide, calcium hypochlorite, 1,2-diaminomethane, formaldehyde, hexamethylbenzene, hydrocarbons, hydroxides, lithium perchlorite, m-methyl aniline, nickel peroxide, nitric acid, metal oxides, potassium hydride, potassium hydroxide, sodium hydride. Mixtures with ammonia, aniline, diethylenetriamine, metal oxides, methyl amine, morpholine, phosphoric acid, silver nitrate form shock-sensitive compounds. Forms high-explosive compound with urea perchlorate. Mixtures with hydrocarbons and other combustible materials can cause fire and explosions. Attacks some plastics, rubber, and coatings.

Reductions with nickel-aluminum/formic acid CN... 

Reduction of the acid stage to the aldehyde 2S8 or 290 is possible by catalytic hydrogenation of the corresponding a-ketophosphonic esters [615] and subsequent termal [617] or alkaline [618] decomposition of the a-hydroxyphosphonic esters. Another possibility is the selective reduction of the ester with deactivated aluminum-hydrides [619] or catalytic reduction of the acid chloride [620]. On a bench scale, reduction of the bromofluoro benzonitrile with Raney nickel in formic acid [621] is particularly advisable. 

Let us consider in greater detail what takes place at the anode when corrosion occurs. For instance, reconsider Eq. (3.6). This reaction involves the reduction of hydrogen ions to hydrogen gas, according to Eq. (3.5). This hydrogen evolution reaction occurs with a wide variety of metals and acids, including hydrochloric, sulfuric, perchloric, hydrofluoric, formic, and other strong acids. The individual anodic reactions for iron, nickel, and aluminum are listed as follows ...
