What N,N-Dimethylethanolamine is, and why buyers source it

A working overview of the compound's chemistry, its place as a fully N-methylated tertiary alkanolamine, and the grades Chelora Chemicals keeps in regular supply.

N,N-Dimethylethanolamine carries a tertiary amine (no N–H bonds, both nitrogen positions methylated) alongside a terminal hydroxyl group. With no N–H to compete, the nitrogen is a clean, sterically accessible base and nucleophile, while the hydroxyl remains independently reactive — a combination that makes the molecule useful both as a catalytic base in its own right and as a building block whose hydroxyl can be further functionalised.

At room temperature it is a colourless, viscous liquid with a fishy, ammoniacal odour, fully miscible with water and most polar organic solvents. It is handled with the solvent-class and corrosivity precautions typical of tertiary alkanolamines.

Where it fits in the synthesis chain

Related tertiary alkanolamines in this structural class are used in gas treating to remove hydrogen sulfide from sour gas streams; N,N-dimethylethanolamine itself is widely used as a curing agent and accelerator for polyurethane foams and epoxy resin systems, where its tertiary amine catalyses the relevant cure reactions. It also serves as a precursor to nitrogen mustard-type compounds in specialty chemistry, and its acrylate ester (2-(dimethylamino)ethyl acrylate, DMAEA) is a well-known cationic monomer used to make flocculating polymers for water treatment.

Grades we supply

Chelora Chemicals offers N,N-Dimethylethanolamine in technical grade (≈98% assay) for standard polyurethane and epoxy catalyst use, and high-purity grade (99%+) for specialty monomer and pharmaceutical-adjacent applications sensitive to colour and trace-impurity content. Both grades are supplied with a batch-wise certificate of analysis.

02 / MANUFACTURING ROUTE

How N,N-Dimethylethanolamine is made

An overview of the production route for orientation purposes. Our manufacturing partners' own process parameters and in-process controls are proprietary and are not disclosed beyond what is needed to interpret the certificate of analysis.

N,N-Dimethylethanolamine is manufactured by ethoxylating dimethylamine with ethylene oxide: (CH₃)₂NH + C₂H₄O → (CH₃)₂NCH₂CH₂OH. The reaction is run under controlled temperature and pressure to favour the mono-ethoxylated product, and the crude amine is purified by fractional distillation to the required assay before packing.

Why the ethoxylation route is preferred

Direct ethoxylation of dimethylamine with ethylene oxide is continuous, scalable and gives high conversion with straightforward downstream distillation — the same general process family used across the ethanolamine range in this catalogue.
