Methyl Diethanolamine (MDEA Amine) Supplier in Malaysia
- Also known as
- MDEA
- N-Methyldiethanolamine
- Methyldiethanolamine
- NMDEA
Methyl diethanolamine supplier for oil and gas, polyurethane, construction and industrial buyers in Malaysia. Also called MDEA amine, N-methyldiethanolamine, methyldiethanolamine or NMDEA, this tertiary alkanolamine is a clear hygroscopic liquid chosen for selective acid-gas treating and related process duty.
Commercial material is offered as technical or high-purity anhydrous liquid and as formulated aqueous gas-treating solutions. Neat product supports make-up and industrial use, while aqueous solutions serve amine units that specify a ready solvent strength. Assay, colour and solution strength are confirmed against the required grade.
Gas processors use methyl diethanolamine for gas sweetening and selective hydrogen sulphide removal, often citing lower regeneration energy than primary or secondary ethanolamines. Other buyers specify MDEA in polyurethane catalysis, cement grinding aids, textile additives, metalworking packages and selected intermediates.

Safety and handling
Store sealed in a cool, dry place and protect from moisture. Methyl diethanolamine is hygroscopic; handle with gloves and eye protection, avoid prolonged skin or vapour contact, and follow the safety information for the quoted grade.
Common questions about methyl diethanolamine
Is methyl diethanolamine the same as DEA, MEA or TEA?
No. Methyl diethanolamine (MDEA, N-methyldiethanolamine) is a tertiary alkanolamine and is a different chemical from diethanolamine (DEA), monoethanolamine (MEA) and triethanolamine (TEA). Each has its own CAS number and typical process role. Order the amine named on your specification; do not substitute one for another without process review.
What is MDEA amine used for in gas sweetening?
MDEA is widely used as a gas-treating amine for acid-gas removal, including selective hydrogen sulphide absorption from natural gas, refinery gas and related streams. Buyers often choose it where lower regeneration energy or H2S selectivity relative to primary or secondary ethanolamines is important. Suitability still depends on the unit design and the required solvent grade.
Which methyl diethanolamine grade should a buyer request?
Technical anhydrous liquid covers many industrial and make-up duties. High-purity cuts are requested when colour or impurity control is tighter. Aqueous gas-treating solutions are ordered when the amine plant specifies a formulated strength rather than neat product. State the form, assay or strength and process so the quotation can match the requirement.
What specifications should be included in an MDEA enquiry?
Provide the required form (anhydrous liquid or aqueous solution), assay or strength if known, appearance or colour preference, application, quantity and delivery location. If you already run a production grade, include the current specification or COA limits so the offered material can be matched more closely.
Can documentation and packing be requested with the quotation?
Yes. List the product documents and preferred pack format in the enquiry. Available documentation, packing and commercial details are confirmed for the quoted methyl diethanolamine grade.
What details are needed for a methyl diethanolamine price enquiry?
Provide the grade or solution strength, application, target specification, quantity and delivery location. Mention any preferred packing and documentation needs so the quotation can address the full requirement.
