Dimecrorl / TitradeS DimesCyl Amines (DMA1214)

Kaddarorin

♦ Tsarin sunadarai

Dodecyl/Tetradecyl Dimethyl Amines;

Dodecyl dimethyl amine: C12H25N(CH3)2 (12-carbon alkyl chain).

T etradecyl dimethyl amine: C14H29N(CH3)2 (14-carbon alkyl chain).

Classification: Tertiary amines with two methyl groups and a long alkyl chain, acting as cationic surfactants when protonated.

♦ Halin duniya

C12-14-alkyldimethyl amines is colorless to light yellow liquids, possibly with a slight odor depending on purity

♦ Socighility

Dodecyl/Tetradecyl Dimethyl Amines(DMA1214) Sparingly soluble in water, highly soluble in organic

solvents (e.g., barasa, ELES, Hydrocarbons).

♦ Hakikanci

C12-14-alkyldimethyl amines weakly basic (pKa ~9–10), forming salts with acids.

♦ Melting & Boiling Points:

C12-14-alkyldimethyl amines vary with alkyl chain length. Dodecyl dimethyl amine (C12) has a melting point

of ~15–20°Cand boiling point of ~240–250°C; tetradecyl dimethyl amine (C14) melts at ~25–30°C and boils at ~280–300°C.

♦ Surface Activity:

Dodecyl/Tetradecyl Dimethyl Amines(DMA1214) Amphiphilic structure reduces liquid surface tension.

♦ Weak Alkalinity

Dodecyl/Tetradecyl Dimethyl Amines(DMA1214) Reacts with acids to form quaternary ammonium salts,enhancing water solubility.

♦ Hutun

C12-14-alkyldimethyl amines can be further derivatized into cationic surfactants (e.g., quaternary compounds)

or betaine-type amphoteric surfactants.

♦ Surfactant Raw Materials

— Cationic Surfactants: Used in detergents, masana'anta masu suttura, and hair conditioners (e.g., quaternary ammonium salts).

— Biocides: Quaternary derivatives are common in disinfectants (e.g., benzalkonium chloride)

♦ Industrial Auxiliaries

–Petroleum Industry: As corrosion inhibitors, demulsifiers, or drilling fluid additives.

–Textile Industry: Antistatic agents and softeners.

–Metalworking: Lubricants and rust preventives.

♦ Cosmetics & Personal Care

Emulsifiers, thickeners, and conditioning agents for hair and skin.

♦ Other Uses

Intermediates for synthesizing amides, imidazolines, and other amine-based compounds.

 

Tsarin Samfura

♦ Raw kayan aiki

–Fatty Alcohols: Derived from coconut or palm oil hydrogenation to produce C12 (dodecanol) and C14 (tetradecanol).

–Dimethylamine (DMA): Serves as the amination reagent.

♦ Yanayin dauki

–Catalyst: Nickel- or copper-based catalysts (e.g., Cu-Ni alloy).

–Temperature & Pressure: Reaction occurs at ~180–220°C under 3–5 MPa.

–Reaction Equation:R-OH+(CH3​)2​NhCatalyst​R-N(CH3​)2​+H2​O (R = C12 or C14 alkyl chain).

♦ Rabuwa da tsarkakewa

–Unreacted DMA and water are removed via distillation.

–Fractional distillation yields high-purity dodecyl and tetradecyl dimethyl amines.

♦ Environmental Considerations

Modern processes emphasize green chemistry, using bio-based feedstocks or optimized catalysts to improve selectivity

♦ Bushewa da marufi

Once the DMA1214 product is obtained and purified, galibi ana bushewa don cire duk wani danshi na danshi.

The dried C12-14-alkyldimethyl amines is then packaged in suitable containers, Tabbatar da hatimi mai kyau don kula da ingancinsa.

Adequate labeling and storage conditions are maintained to ensure safe handling and storage of the product.
