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 NH+ H(here RXis NH3) Then, the three condensation reactions: 

 

NHEO  NH2CH2CH2OH (mono-ethanol amine MEA) 
NH
2CH2CH2OH + EO  NH(CH2CH2OH)(di-ethanol amine DEA) 
NH-(CH
2CH2OH)EO  N(CH2CH2OH)(tri-ethanol amine TEA) 

With an alkyl amine, first the alkyl ammoniumion is formed and it is deprotonated: 

RNH3 RNH+ H(here RXis RNH2)
RNH
EO  RNH-CH2CH2OH (mono-ethanol alkyl amine) 
RNH-CH
2CH2OH + EO  RN(CH2CH2OH)(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.

DEA - DI ETHANOL AMINE is most commonly used as a surfactant in cleaning industries and as a corrosion inhibitor in oil field industries. DI ETHANOL AMINE chemically reacts and remove hydrogen sulfide and carbon dioxide from natural gas due this property DEA used in oil refineries as a deodourizer to remove hydrogen sulfide from sour gas.
