DiEthanolAmine-modified Sodium Lignosulfonate (DEA-SL) admixture for cement slurries, enhancing early strength and fluidity.

SKU: RXSOL-67-1119-210 Category:

Description

Diethanolamine-modified sodium lignosulfonate (DEA-SL) admixture for cement slurries, enhancing early strength and fluidity. DEA-SL reduces thickening time by 68%, increases fluidity by 10.5%, and Decreases Shrinkage by 26% via synergistic effects of electrostatic repulsion (SO3−), steric hindrance, and accelerated hydration (Ca²⁺ chelation). The renewable lignin-based design offers scalable, sustainable solutions for rapid construction and low-carbon cementitious materials.

DEA – DI ETHANOL AMINE supplier and exporter. Diethanolamine is widely used in the preparation of diethanolamides and diethanolamine salts of long-chain fatty acids that are formulated into soaps and surfactants used in liquid laundry and dishwashing detergents, cosmetics, shampoos and hair conditioners.






Product Details

Application

 

Diethanolamine-Modified Sodium Lignosulfonate Admixture for Early Strength and Water Reduction in Cement Slurry

 

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.

Dosage & Procedure

Diethanolamine is a white, crystalline (sand-like) solid or a colorless to yellow, syrupy liquid with a mild Ammonia-like odor. It is used in specialty textiles, weed killers, detergents, shampoos, paints and metal-working fluids.

Notes & Precautions

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.
