Application

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.

Using Procedure

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.

Note

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: 


<div class="page" title="Page 17">
<div class="layoutArea">
<div class="column">

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.
