    Methylamine (CH5N) contains 5 hydrogen atoms per one carbon atom what makes it one of the cleanest fuels.What is approximate energy density (MJ/kg) of this substance?
    What could be the price to synthetize it in huge quantities in comparison to synthetic gasoline?What additives could be added to methylamine in small quantities to make it less poisonous?

    The cheapest way to produce methylamine would be by reacting ammonia with existing hydrocarbons. You'd end up with the same amount of carbon dioxide as if you'd burnt the fossil fuels directly, since you're still burning the same amount of carbon atoms - except that you've lost a portion of the energy by reacting it with ammonia to produce methylamine (I'm not sure if these reactions are endothermic, but you have to consider the energy needed to produce the ammonia). It makes far more sense to burn the fossil fuels directly.

    Also, I wouldn't say methylamine burns "cleanly", since you're talking about producing equal volumes of carbon dioxide and nitrogen oxides (think acid rain).

    I asked rather about comparison of producing methylamine to synthetic gasoline from coal prices.As I know synthetic gasoline is produced usually through methanol.
    Methylamine could be produced by reacting methanol with ammonia.Not to different cycle though.

    I found some ractions of methylamine reacting thermally with oxygen and it seems that formation of oxygen nitrides is not typical.

    2CH3:NH2+O2=2CH2O+2NH3............................ ..................4NH3+2O=6H2O+2N2.

    Also nitrogen oxygen nitrides could be eliminated or drastically reduced with help of catalysts while carbon dioxide can`t.I don`t know but currently some fuels such as hydrogen are pushed just because of they are ``clean``.

    Ah, ok. In which case, I have to say that I don't know enough about the subject to answer. Experimental data would be the way forwards; determining the net enthalpy change for both processes, and comparing this to the cost of each.

    stanley, this site may provide all the information you need to evaluate your hypothesis: http://encyclopedia.airliquide.com/E...a.asp?GasID=43
    physics: accurate, objective, boring
    chemistry: accurate if physics is accurate, slightly subjective, you can blow stuff up
    biology: accurate if chemistry is accurate, somewhat subjective, fascinating
    religion: accurate if people are always right, highly subjective, bewildering

    highly corosive liq and gas,boils at -6C, high inhalation hazzard LD50 -2400mg/M3
    not too practicle for the general public

    Also - I am not sure how DEA and other respective authorities would feel about its availability to the public.

    Feel free to correct any false information, which unknown to me, may be included in my posts. (also - let this be a disclaimer)

    Per your attached paper, the decomposition in oxygen of CH3:NH2 is NOT most likely NOx (as listed in its MSDS), but unfortunately, more problematic.

    To list the products in order of concentration: NH3, CO2, CO, HCN, CH2O and N2.

    In addition, the Methylamine appears to be somewhat toxic via inhalation.

    Not an ideal fuel substitute.

    What idiot then uses methanol as fuel?Is it not highly toxic?

    racing engines use meth alc fuel routinely , toxic only if you inhale or drink it. meth-amine is ridilious as a fuel - forget it
