- Methylamine is the
organic compound with a formula of CH₃NH₂. This colourless gas is a
derivative of ammonia, but with one H atom replaced by a methyl
group.
- Methylamine is the
simplest primary amine.
- Methylamine is sold
as a solution in methanol, ethanol, THF, and water, or as the anhydrous
gas in pressurized metal
containers.
- Industrially
methylamine is sold in its anhydrous form in pressurized railcars and
tank trailers. It has a strong odor
similar to fish.
- Methylamine is used
as a building block for the synthesis of many other commercially
available compounds. Over 1 million tonnes are produced annually.
- Methylamine occurs
naturally in a variety of foods and beverages.
- Methylamine is
prepared commercially by the reaction of ammonia with methanol in the
presence of a silicoaluminate catalyst. Dimethylamine and trimethylamine
are coproduced; the reaction kinetics and reactant ratios determine the
ratio of the three products.
- In particular, mono
methylamine consumed for pesticides (2.5 percent annually), and
alkylalkanolamines (2.7 percent annually); and dimethylamine used for
water treatment polymers (5.9 percent annually); dimethyl amino
propylamine (13.5 percent annually); and dimethylaminoethanol (7.5
percent annually). Totaled, these segments represented 49 percent of
demand last year.
- Market demand in 2002
was split between the different products as: monomethylamine, 88 million
pounds (21 percent); dimethylamine, 257 million pounds (63 percent);
trimethylamine, 67 million pounds (16 percent).
- More than 90 percent
of methylamines imported into the US originate in Canada.
- Taminco is one of the
world's significant producers of mono-, di- and trimethylamines Taminco
also specializes in methylamine derivatives.
- There are three
species of methylamines being produced namely MMA, DMA and TMA.
- Methylamine has many
applications in various industries. It is an important intermediate in
the manufacture of a variety of products includingpharmaceuticals
(e.g.,ephedrine), pesticides (e.g., 1-naphthyl-N-methyl carbamate, Vapam),
explosives, surfactants, and accelerators.
- Methylamine is commonly used in the tanning and dyeing
industries and as a fuel
additive.
- Methylamine is also used as a polymerization inhibitor, a
component of paint removers, a solvent, in the manufacture of
photographic developers , and as a rocket propellant.
- Methylamine has also
been reported to be a precursor chemical used in the illicit manufacture
of methamphetamine
- Methylamine has also
been detected in milk (7.9 mmol/100 g), cheese pizza (2.9 mmol/100 g),
green beans (4.9 mmol/100 g), commercial samples of wine (0.19 mg/mL in
red wine, 0.14 mg/mL in white wine), uncured and cured pork (1,490 mg/kg
and 730 mg/kg, respectively), and at high levels in squid, octopus, and
other seafoods (up to a mean of 255 ppm).
- Methylamine has been
detected in ambient air and rainwater. A Japanese study detected
methylamine in air samples from a poultry farm (0.52 ppb) and a
fermentation system for poultry wastes (0.97 ppb) and in emission gas
from an incinerator of poultry wastes (12.4 ppb).
