Methylamine Applications

How you can use them

Methylamines are utilized in a wide range of applications and processes. The following includes some of the many applications of our customer base.

Mono-methylamine: MMA

Di-methylamine: DMA

Tri-methylamine: TMA

Agricultural Chemicals


Different methylamines are used to make intermediates for many agri chemicals including herbicides, fungicides, insecticides, biocides & miticides.

  • MMA reacted with carbon disulfide & caustic produces metam-sodium: which is used as a soil fumigant & sterilant (replacing methyl bromide- ozone depleter).
  • Phosgenated MMA is used to produce methyl isocyanate: which is used to manufacture insecticides.
  • DMA is used to produce herbicides & fungicides such as:

‒Ferbam: Fungicide for apples & tobacco

‒Ziram: Fungicide for vegetables

‒Thiram: Disinfectant for grains, bulbs, tubers & corn

  • TMA reacted with SO2 produces a volatile insecticide

Animal Nutrients


TMA is used to produce choline chloride, a B vitamin supplement in animal feed for chickens, turkeys & swine.



Methylamines are used directly as catalysts or as raw materials to produce other compounds with catalytic activity.

  • MDEA made from MMA is used as a urethane catalyst.
  • DMAE made from DMA is also used as a urethane catalyst to promote foam rise & gel strength for insulation applications (appliances).
  • Hydrochlorides of MMA & DMA in the presence of cupric chloride are used for the polymerization of acetylene to vinyl & devinyl acetylene.
  • MMA & DMA are used as catalysts for the dealdolization of diacetone alcohol.
  • TMA is a catalyst for ethyl alcohol to ethylene oxide and for Diels-Alder diene association reactions.
  • DMA & calcium sulfate are used to prepare dinitroalkanes & nitro-olefins.
  • MMA & DMA can be used for the condensation of phenol & formaldehyde.
  • DMA is a catalyst to condense acetone with formaldehyde to produce synthetic resins used in paper bonding & coating.



  • DMA is used to make benzyldimethylamine which is used as an accelerator for epoxy resins in laminates for electrical equipment.
  • TMA is used to make tetramethylammonium hydroxide which is a stripper for resists in printed circuit boards.

Fuel Additives


Fuel additives are used to improve engine performance in a variety of ways.

  • DMCHA & DMAPA made from DMA are used for gasoline & motor oil additives.
  • MMA & chlorobenzene are reacted with copper as a catalyst to make n-methylaniline for aviation fuel.
  • DMA hydrochloride is also used as an aviation fuel additive as an antiknock compound.
  • MMA nitrate is a freezing point depressant in jet engines using ammonium nitrate-urea fuels.
  • Mixtures of MMA, DMA & TMA in water have been tested as coolants in some high-speed engines.


Gas & Oil Treatment


  • MMA reacted with ethylene oxide produces methyldiethanolamine (MDEA) & monomethylethanolamine (NMEA): MDEA is used to remove acidic components in natural gas such as H2S, mercaptans, carbonyl sulfide & CO.
  • DMA reacted with CO2 produces dimethylammonium: used to remove sulfur compounds, olefins & aromatic hydrocarbons from raw oil.

Paper Chemicals


  • Both DMA, TMA are used to produce cationizing starches

Personal Care


  • DMA is used to produce n,n-dimethylaminopropylamine & DMDAC which are used to make cosmetics, liquid soaps, hand lotions, shaving cream & shampoos.



  • MMA reacted with ethylene oxide creates methyldiethanolamine (MDEA) and monomethylethanolamine (NMEA) which are used to make analgesics with sedative and antispasmodic effects.
  • MMA reacted with phosgene yields n,n-dimethylurea used to make xanthine derivatives.
  • MMA reacted with phenylsuccincic acid yields phensuximide which is an anticonvulsant.
  • MMA is used to make intermediates for the production of tranquilizers, antidepressants muscle relaxants & x-ray contract mediums.
  • MMA is used to produce sympathomimetic drugs.
  • DMA is used to produce intermediates to manufacture antihistamines.
  • DMA is used in the synthesis of local anesthetics.
  • DMA is used to manufacture propoxyphen analgesic & doxepin antidepressants.
  • Salicylates of MMA & DMA are used as ointments for skin disorders.
  • DMA is used to make intermediates for tranquilizing agents.


Resin Manufacturing


  • DMA is used to manufacture anionic resins.
  • TMA is used to manufacture cationic exchange resins.

Rubber Chemicals


  • DMA is used to make dimethyldithiocarbamate salts used for vulcanization accelerators.
  • DMA oleate is an emulsifier for use in synthetic rubber production.
  • DMA is used directly as a modifier in the vapor phase polymerization of butadience & as a stabilizer for natural rubber latex.



  • DMA reacted with CO produces dimethylformamide (DMF): which is used in urethane coatings, spinning solvents (primarily for acrylics), reaction solvents, extraction solvents & processing solvents.
  • MMA reacted with acetic acid produces dimethylacetamide (DMAC): which is used as spinning solvent & reaction solvent and for the manufacture of dyes, pharmaceuticals & vinyl polymers.
  • MMA reacted with gammabutyrolactone produces n-methylpyrrolidone (NMP): which is used as reaction solvent (engineering resins), extraction solvent (lube oil refining), spinning solvent, paint stripper, electronics (for strippers and cleaners) and enamel coatings (magnet wire with polyamide/imide resins).



  • DMA is used to produce some specialty surfactants which are used in the manufacture of soaps, shampoos, detergents & other specialty wetting applications.

Water Treatment


  • DMA is used as a raw material to product agents that remove suspended solids for water clarification in industrial & municipal water/wastewater treatment plants. They are used to improve sold/liquid separation in sedimentation, filtration and flotation operations.
