Frequently asked questions
What is C12-14 alkyldimethyl amine and what is it used for?
Amines, C12-14 Alkyldimethyl (CAS 68439-71-4) is a long-chain tertiary amine that serves as the key intermediate for cationic surfactants. It is used to make quaternary ammonium compounds, amine oxides and betaines, as well as fabric softeners and disinfectants.
Is this product a cationic surfactant or an intermediate?
C12-14 alkyldimethyl amine is a tertiary amine; it is not a surfactant itself but the intermediate for cationic surfactants. Through quaternization or oxidation it is converted into quaternary ammonium compounds, amine oxides and betaines. Its CAS number is 68439-71-4.
How is C12-14 alkyldimethyl amine stored and transported?
This amine is stored in a cool, dry, well-ventilated area, away from acids and oxidizers. Its shelf life is 12 months. It is transported as a corrosive liquid under UN 2735, in drums or IBCs, with bulk available on request.
What do the total amine value and 98% purity mean?
The product is supplied at a minimum purity of 98.0%, with a total amine value of 240–260 mgKOH/g, most of which (238–258 mgKOH/g) is tertiary amine. Primary plus secondary amine is max 0.3%. The full specification and a certificate of analysis are provided by KORKİMYA.
