Mono Ethanol Amine MEA
Monoethanolamine - RXSOL brand MEA iron and chloride free grade.
Monoethanolamine Mea supplier and stockist. MEA is A clear, water-white, hygroscopic liquid with a mild ammoniacal odor.
RXSOL brand MEA iron and chloride free grade and Purity wise doen't contains <= 1 ppm chloride, <= 0.5% pm iron. Absolutely free from impurities makes PURE MEA to absorbe more CO2. On the other hand Purity of MEA optimizing CO2 absorption properties.

MEA is usfull products fo Gas-scrubbing agent for the absorption and removal of H2S and CO2 ( Acidic Odor ), And MEA have large field of application as detergent, Fabric Softner, Wood Treating agent etc..
BIODEGRADABILITY AND ENVIRONMENTAL SAFETY Monoethanolamine undergoes moderate biodegradation and is not expected to be persistent in the environment.
A chemical intermediate in the manufacture of cosmetics, surface-active agents, emulsifiers, pharmaceuticals, and plasticizing agents; a gas-scrubbing agent for the absorption and removal of H2S and CO2 from refinery and natural gas streams; carbon dioxide and ammonia manufacturing. It has various use also applications include use as “down hole” in oil well chemicals and in metalworking to prevent corrosion, and as catalysts that promote stability during the reaction process in the manufacture of flexible and rigid urethane foams.
MEA play important role in Detergents imparts a reserve alkalinity to the laundry bath, which is essential to efficient cleaning. MEA is an effective oil and anti-redeposition agent.
Fatty acids neutralized with MEA are used as emulsifiers for oil-in water emulsions such as gel-type industrial hand cleaners, aerosol shave creams, and hand and body lotions.
Textile Finishing
MEA is used as reaction intermediates for the preparation of durable press fabric finishes and softeners. • When reacted to form amine soaps, useful as scouring agents for wool and silk because of its low alkalinity. • Because it is hygroscopic, MEA is used in the preparation of vat printing pastes.
Wood Treating
MEA is used in both alkaline copper quaternary (ACQ) and copper azole formulations for treating wood to improve its resistance to pests and decay. Both are arsenic-free alternatives to the phased-out CCA formulations.
If RXH is not acid enough to release a proton at alkaline pH, as it is the case with amines, then the reaction has to be carried out in two steps. During the first step the first EO mole is added at acid pH, so that the amine is transformed in ammonium. The reaction produce the mono-, di- and tri-ethanol amines.
Proton release from ammonium NH4+ → NH3 + H+ (here RX- is NH3) Then, the three condensation reactions:
NH3 + EO → NH2CH2CH2OH (mono-ethanol amine MEA)
NH2CH2CH2OH + EO → NH(CH2CH2OH)2 (di-ethanol amine DEA)
NH-(CH2CH2OH)2 + EO → N(CH2CH2OH)3 (tri-ethanol amine TEA)
With an alkyl amine, first the alkyl ammoniumion is formed and it is deprotonated:
RNH3+ → RNH2 + H+ (here RX- is RNH2)
RNH2 + EO → RNH-CH2CH2OH (mono-ethanol alkyl amine)
RNH-CH2CH2OH + EO → RN(CH2CH2OH)2 (di-ethanol alkyl amine)
Once the ethanol amine is attained, the EO polycondensation is carried out at alkaline pH as previously. In many instance the first ethoxylation is stopped when the monoethanol alkyl amine is formed in order to avoid the polycondensation in more than one chain.

TOXICITY AND SAFETY :
For information on the toxicity and safe handling of this product, please read the Material Safety Data Sheet prior to use of the product.
HANDLING AND STORAGE :
Monoethanolamine may be satisfactorily stored in carbon steel, stainless steel, or aluminum tanks using steel pipes and pumps. Caution must be exercised, however, to keep the material in the anhydrous state to prevent severe corrosion to the carbon steel or aluminum tank and related equipment. A drier on the breathing nozzle is recommended to help maintain anhydrous conditions in the storage tank. For longer term color stability, it is recommended that the product be stored under an inert atmosphere. Solid sediment may form upon standing. There should be circulation in the storage vessel to keep solids suspended. Low pressure steam coils in storage tanks and heat tracing of transfer lines should be provided in cases where low environmental temperatures may make pumping of the product difficult.
